Answer:
No, although the thoughts, hopes, dreams and aspirations entirely the results of physiological processes: Love, hate, anger and memories are not only at the synaptic level because some or part of human behavior and reaction are due to nature and nurture rather than totally dependent on the external stimuli or nurture
Explanation:
The physiological process can be described as a part of a system that plays a role on how the brain works and in inventory management, a part of a product are items that can be counted in inventory and can then be sold or used internally while a product is an item only meant to be sold.
Therefore, a product consist of all the integral parts required to complete a given function
A product such as what determines emotions, aspirations, thoughts, hopes and dreams has only one predetermined purpose or a process which it fits into even before if was sold or made, just like a bus bought to carry future employees of a company that is having a new site office.
While a part such as the fan belt can be changes and used on other vehicles without altering the journey of the bus.
A system is more than just its integral part as the system was desirable even before it was made while a part is made because of the system.
For a rigid axisymmetric satellite, the mass moment of inertia about its long axis is 1000 kg$m2 , and the moment of inertia about transverse axes through the center of mass is 5000 kg$m2 . It is spinning about the minor principal body axis in torque-free motion at 6 rad/s with the angular velocity lined up with the angular momentum vector H. Over time, the energy degrades due to internal effects and the satellite is eventually spinning about a major principal body axis with the angular velocity lined up with the angular momentum vector H. Calculate the change in rotational kinetic energy between the two states. {Ans.: 14.4 kJ}
Answer: Delta T = - 14.4 kJ
Explanation:
Firstly the initial momentum of the satellite is;
H0 = L0*W0
L0 is the momentum of inertia of the satellite about its longer axis (1000 kg.m^2) and Wo is the initial angular velocity of the satellite ( 6 rad/s)
now we substitute
H0 = 1000 kg.m^2 * 6 rad/s
H0 = 6000 kg.m^2
Now the initial rotational kinetic energy of the satellite is;
0o = 1/2L0W0^2
we substitute
T0 = 1/2 * (1000 kg.m^2) * (6 rad/s)^2
T0 = 18000
Next is the final angular momentum of the satellite;
H = IW
I is the moment of inertia of the satellite about its transverse axes through center of mass (5000 kgm^2)
we know that the law of conservation angular momentum, the total initial angular momentum of the satellite is equal to the total final angular momentum of the satellite.
simply put H = H0
we know that our H0 = 6000 kgm^2
so we substitute
H0 = IW
6000 kg.m^2 = 5000 kgm^2 * W
W = 1.2 rad/s
The final rotational kinetic energy of the satellite is;
T = 1/2IW^2
T = 1/2 * 5000 kgm^2 * 1.2^2
T = 3600 J
so the change in rotational kinetic energy of the satellite is;
Delta T = T - T0
Delta T = 3600 - 18000
DeltaT = - 14400 J
Delta T = - 14.4 kJ

Which of the following statements about Gaussʹs law are correct? (There may be more than one correct choice.) Question 3 options: Gaussʹs law is valid only for symmetric charge distributions, such as spheres and cylinders. If there is no charge inside of a Gaussian surface, the electric field must be zero at points of that surface. Only charge enclosed within a Gaussian surface can produce an electric field at points on that surface. If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface.
Answer:
If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface.
Explanation:
Option A is incorrect because, given this case, it is easier to calculate the field.
Option B is incorrect because, in a situation where the surface is placed inside a uniform field, option B is violated
Option C is also incorrect because it is possible to be a field from outside charges, but there will be an absence of net flux through the surface from these.
Hence, option D is the correct answer. "If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface."
g Describe how an electron can possess the properties of both a particle and a wave. How do the wave properties of electrons relate to the Heisenberg uncertainty principle? Electrons possess the properties of particles in that they ---Select--- . However, Louis de Broglie theorized that matter can also show wave properties, specifically characteristic wavelengths based on its mass and velocity. The wave properties of electrons were observed by their ability to ---Select--- when passed through a crystal, similar to the diffraction of electromagnetic waves. The Heisenberg uncertainty principle states that wave properties of electrons ---Select--- the exact location of an electron in space.
Answer:
See explanation
Explanation:
According to Louis de Broglie, matter has an associated wavelength. Hence, there exist no clear cut difference between matter and wave. Matter may be regarded as a wave and vice versa depending on the behavior of each under the given circumstances.
According to Heisenberg uncertainty principle, the position and momentum of matter can not be simultaneously determined with precision. This further reinforces the wave-particle concept of the electron.
When electrons are passed through crystals, they are diffracted just like electromagnetic waves. This further reinforces the wave-particle paradox.
According to The Heisenberg uncertainty principle, the wave property of electrons determine their exact location in space
It should be noted that an electron can possess the properties of both a particle and a wave as the electron propagates through space.
What is an electron?It should be noted that electron simply means a particle whose electric charge is a negative one.
In this case, an electron can possess the properties of both a particle and a wave as the electron propagates through space.
Therefore, it interacts at a point like a particle. This is important for the electron to travel through the nucleus of the atom.

1. A mountain climbing expedition establishes a base camp and two intermediate camps, A
and B. Camp A is 11,200 m east of and 3,200 m above base camp. Camp B is 8,400 m
east of and 1,700 m higher than Camp A. Determine the displacement between base camp
and Camp B.
Answer:
Explanation:
The diagram showing the illustration of the question is shown on the first uploaded image
Here G represents the base
So the displacement in the x -axis is mathematically represented as
[tex]X = 11200 + 8400 = 19600 \ m[/tex]
The displacement in the y -axis is mathematically represented as
[tex]Y 3200 + 1700 = 4900 \ m[/tex]
Generally the resultant displacement is
[tex]R = \sqrt{ X^2 + Y^2}[/tex]
[tex]R = \sqrt{ 19600^2 + 4900^2}[/tex]
[tex]R = 20200\ m [/tex]
Generally the direction of this resultant displacement is mathematically represented as
[tex]\theta = tan ^{-1} [\frac{Y}{X} ][/tex]
=> [tex]\theta = tan ^{-1} [\frac{4900}{19600} ][/tex]
=> [tex]\theta = 14.03 ^o [/tex]
Hence the direction is [tex]14.03 ^o[\tex] from the horizontal axis

A horizontal spring is attached to a wall at one end and a mass at the other. The mass rests on a frictionless surface. You pull the mass, stretching the spring beyond the equilibrium position a distance A, and release it from rest. The mass then begins to oscillate in simple harmonic motion with amplitude A. During one period, the mass spends part of the time in regions where the magnitude of its displacement from equilibrium is greater than (0.30)A— that is, when its position is between −A and (−0.30)A, and when its position is between (0.30)A and A. What total percentage of the period does the mass lie in these regions?
Answer:
Δt'/ T% = 90.3%
Explanation:
Simple harmonic movement is described by the expression
x = A cos (wt)
we find the time for the two points of motion
x = - 0.3 A
-0.3 A = A cos (w t₁)
w t₁ = cos -1 (-0.3)
remember that angles are in radians
w t₁ = 1.875 rad
x = 0.3 A
0.3 A = A cos w t₂
w t₂ = cos -1 (0.3)
w t₂ = 1,266 rad
Now let's calculate the time of a complete period
x= -A
w t₃ = cos⁻¹ (-1)
w t₃ = π rad
this angle for the forward movement and the same time for the return movement in the oscillation to the same point, which is the definition of period
T = 2 t₃
T = 2π / w s
now we can calculate the fraction of time in the given time interval
Δt / T = (t₁ -t₂) / T
Δt / T = (1,875 - 1,266) / 2pi
Δt / T = 0.0969
This is the fraction for when the mass is from 0 to 0.3, for regions of oscillation of greater amplitude the fraction is
Δt'/ T = 1 - 0.0969
Δt '/ T = 0.903
Δt'/ T% = 90.3%

PLEASE HURRY! The highest speed ever achieved on a bicycle was reached by John Howard of the United
States. The bicycle, which was accelerated by being towed by a vehicle, reached a velocity
of 6.81 m/s. Suppose Howard wants to slow down, and applies the brakes on his now freely
moving bicycle. If the average acceleration of the bicycle during braking is -3.0 m/s2
, how
long will it take for the bicycle’s velocity to decrease to 5.44 m/s?
Well, to begin with, your first number gang somewhat aglay. The land speed record that John Howard set on his bicycle in 1985 was 152.2 miles per hour, which works out to 68.04 m/s. So I can see where you got the 6 and the 8 from, but your little decimal point snuck over one place when you weren't looking.
I'll use your number to answer the question. If my solution turns out to be wrong, then it's because you copied the number wrong, and you'll have to work it out again with an initial speed of 68.1m/s.
Initial speed = 6.81 m/s
Final speed = 5.44 m/s
Amount of slowing down = 1.37 m/s
Rate at which the brakes slow you down = 3 m/s each second
Time needed to slow down 1.37 m/s = (1.37 m/s) / (3 m/s^2)
That's 0.457 second. (obviously absurd)
If initial speed = 68.1 m/s
Then amount of slowing down = 62.66 m/s
Time needed at -3 m/s^2 = (62.66/3)
That's 20.9 seconds. Much more reasonable.
By the way, John Howard's record was broken 10 yrs later, in 1995 .
Time it will take for the bicycle’s speed to decrease to 5.44 m/s is 20.9 seconds.
What is speed?The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Given
Initial speed = 6.81 m/s
Final speed = 5.44 m/s
Amount of slowing down = 1.37 m/s
Rate at which the brakes slow you down = 3 m/s each second
Time needed to slow down 1.37 m/s = (1.37 m/s) / (3 m/s^2)
That's 0.457 second. (obviously absurd)
If initial speed = 68.1 m/s
Then amount of slowing down = 62.66 m/s
Time needed at -3 m/s^2 = (62.66/3)
Time it will take for the bicycle’s velocity to decrease to 5.44 m/s is 20.9 seconds.

A group of students are doing an electrostatic experiment. One touches an electroscope with her finger, and a second student then brings a charged plexiglass rod near the electroscope but does not touch it. The first student removes her finger from the electroscope before the second student removes the plexiglass. Meanwhile a third student touches a different electroscope with a charged PVC pipe. Are both electroscopes charged? If so, are they the same charge or different charges? Explain your reasoning. Feel free to include any drawings or diagrams.
Answer:
a) If both are charged
b) the first team has a load and the second half of it
c) The first team has a charge contrary to the rod, it is charged by induction and the second team has a charge equal to the rod, it is charged by contact
Explanation:
For this exercise let's analyze the charge on each electroscope separately
electroscope 1
Suppose the student with her finger on the device is grounded,
When bringing the rod closer to the electroscope a charge is indexed, on the side of the rod on the opposite side there is the same charge but with the opposite sign, as the student is grounded, this charge passes to the ground, this side remains neutral.
When removing the finger, loads can no longer pass, and when removing the rod the load from this side distributes throughout the equipment, therefore it has a load of the same magnitude as the rod
Electroscope 2
In this case, the equipment is touched, so the load redistributes in the two, when separating it remains with half the load of the cheek.
After analyzing each device separately we can answer the questions.
a) If both are charged
b) the first team has a load and the second half of it
c) The first team has a charge contrary to the rod, it is charged by induction and the second team has a charge equal to the rod, it is charged by contact

A 75-kg piano is hoisted on a crane and delivered throughout the window of a 6th story apartment (20 meters above ground). What is the potential energy of the piano?
Answer:
P = 14700 J
Explanation:
Given that,
Mass of a piano, m = 75 kg
It is delivered throughout the window of a 6th story apartment which is 20 m above the ground.
We need to find the potential energy of the piano. It is given by :
P = mgh
Putting all the values,
P = 75 kg × 9.8 m/s² × 20 m
P = 14700 J
So, the potential energy of the piano is 14700 J.
A car speeds up and accelerates for 5.1 seconds at a rate of 2.2 m/s2. if the car's initial velocity was 9.3 m/s, what was the car's final velocity
after accelerating?
-9.7m/s
-11.2m/s
1.9m/s
20.5m/s
Recall the definition of average acceleration:
a = (v - u)/∆t
where u and v are the initial and final velocities, respectively.
So we have
2.2 m/s² = (v - 9.3 m/s) / (5.1 s)
v - 9.3 m/s = (2.2 m/s²) * (5.1 s)
v = 9.3 m/s + (2.2 m/s²) * (5.1 s)
v = 20.52 m/s ≈ 21 m/s

What is the average speed in miles per hour of the car that traveled 200 miles in 5.5 hours
Answer:
36.4 mph
Explanation:
Average speed is [tex]\frac{distance}{time}[/tex].
After substitution, this is [tex]\frac{200}{5.5}[/tex].
The average speed, therefore, reduces to 36 [tex]\frac{4}{11}[/tex] mph, or about 36.4 mph.

3A car travelling at initial velocity 30m/s overtake a bus which was 120m
ahead. The bus then moves with initial velocity 10m/s and accelerate at
5ms-2.
when will the bus also now overtake the car,
what is the time interval
between the arrival of the two cars if the car is to travel a total distance of
450m .
The bus is 120 m ahead of the car, so the car covers this distance in
120 m = (30 m/s) t
t = (120 m) / (30 m/s)
t = 4 s
Now take the car's position at the moment the car overtakes the bus to be the origin.
Car's position at time t :
x = (30 m/s) t
Bus's position at time t :
x = (10 m/s) t + 1/2 (5 m/s²) t²
The bus overtakes the car when their positions are equal:
(30 m/s) t = (10 m/s) t + 1/2 (5 m/s²) t²
t / (2 s) ((5 m/s) t - 40 m) = 0
t = 0 or t = (40 m) / (5 m/s) = 8 s
If the car travels a total distance of 450 m, then it does so after
450 m = (30 m/s) t
t = (450 m) / (30 m/s)
t = 15 s
The bus overtakes the car in the first 12 s of this journey, so both vehicles reach the same destination with 3 s between them.
