A can of tuna, starting from rest, is dropped off a building. If it is only being pulled down by gravity (-
9.8 m/s2) and it hits the ground 3.2s later, how far (Ax) did it drop?
Answer: (displacement/delta x) = -50. m, and distance dropped = 50. m (50. m below the starting location)
Explanation:
We know that the initial velocity of the tuna can is 0 m/s, as it is at rest. Also, we have the acceleration caused by gravity (-9.8 m/s^2). The time for the trip is 3.2 s. We need to find the displacement, or delta x.
To do this, we need to use a freefall equation. The one we can use with initial velocity, time, and acceleration would be the following:
d = (initial velocity)(time) + (1/2)(acceleration caused by gravity)(time)^2
d = (vi)(t) + 1/2(g)(t)^2
d = (0 m/s)(3.2 s) + 1/2(-9.8 m/s^2)(3.2 s)^2
d = 1/2(-9.8 m/s^2)(3.2 s)^2
d = -4.9(3.2)^2
d = -4.9(10.24)
d = -50.176 = -50. m

What is Balanced and Unbalance forces ?Motion of the object is because of Force exerted on it. Balanced forces are those forces which are opposite in direction and equal in magnitude. When resultant force acting on a body is zero then it is called as balanced force. motion of the body is not because of Balanced force. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force.
When resultant of all the forces is not equal to zero then we call it as Unbalanced forces. unbalanced force are responsible for the motion of the body.
Given,
Normal Force in upward direction = 17N
weight mg in downward direction = 17N
in this case both forces are in opposite direction. one is on positive y direction and other one is in negative y direction. Therefore net force acting on the computer desk is given by,
[tex]F^{2} _{net} = F^{2} _{1} + F^{2} _{2} + 2F _{1}F _{2}cos\alpha[/tex].....1
where [tex]\alpha[/tex] = angle between two forces.
[tex]\alpha[/tex] = 180 [tex]cos\alpha[/tex] = -1
[tex]F_{1} = F_{2}[/tex] , 17N =17N
With this equation 1 becomes
[tex]F^{2} _{net}[/tex] = 2F₁²-2F₁² = 0N
Hence net force is 0 N. This is a balanced force.

A method of classifying stars by their age.
A method of classifying stars by their age and distance from the Earth.
Answer: A method of classifying stars by their temperatures and compositions.
Explanation:
The Morgan-Keenan Spectral Classification system is a method of classifying stars by their temperatures and compositions.
What is Morgan-Keenan Spectral classification of star?The primary factor used to categories stars is their temperature.
The Morgan-Keenan luminosity class (MK or MKK) was developed as a result of the Harvard spectral classification classification scheme does not completely describe the star as it cannot distinguish between stars with the same temperature but different luminosities.
Since then, class I stars have been separated into Ia-O, Ia, and Ib, and classes VI (sub-dwarf), and D (white dwarf) have been added, replacing the original roman numerals between I (supergiant star) and V (main sequence).
The original Harvard classification of the star is supplemented by the MK luminosity class in order to fully define it. For instance, the entire classification of the Sun, which is a main sequence G2 star, is G2V.
The MK luminosity class is added to the Harvard classification of the star in order to fully define it.

7. Two bikes travelling in the same direction move at a speed of 30 km/hr. The bikes are separated by a distance of 5 km. What would the speed of the car travelling in the opposite direction be if it meets these bikes at an interval of 4 minutes?
Answer:
Explanation:
Call the bike on the right A
Call the bike on the left B
The car begins it's time when it passes A
4 minutes later, it passes B.
But B has moved in 4 minutes and that is the key to the problem.
How far has B moved.
t = 4 minutes = 4/60 hours = 1/15 of an hour.
d = ?
rate = 30 km / hr
d = r * t
d = 30 km/hr * 1/15 hours = 2 km
The distance between the bikes is 5 km.
So the car has traveled 5 - 2 = 3 km
d = 3 km
r = ?
t = 4 minutes = 1/15 hour
r = d/t = 3/(1/15)= 3 / 0.066666666 = 45 km/hr.
How long will it take to fall 50 m?

A dog chasing a cat has 0.55 times the kinetic energy of the cat, which has 0.45 times the weight of the dog. The dog speeds up by 0.91 m/s and then has the same kinetic energy as the cat. What was the original difference in speed of the dog and cat? In other words, what is v_sub_cat - v_sub_dog initially (before the dog speeds up)?
Answer:
The difference in speed of the dog and cat is 2.65 m/s
Explanation:
Given that,
Mass of cat = 0.45 times the mass of dog
K.E of dog = 0.55 times K.E of cat
We need to calculate the velocity of dog
Using given data
[tex]\dfrac{1}{2}m_{d}v_{d}^2=0.55\times\dfrac{1}{2}m_{c}v_{c}^2[/tex]
[tex]m_{d}v_{d}^2=0.55\times0.45\times m_{d}\times v_{c}^2[/tex]
[tex]v_{d}^2=0.2475\times v_{c}^2[/tex]
[tex]v_{d}=0.497v_{c}[/tex]....(I)
The dog speeds up by 0.91 m/s and then has the same kinetic energy as the cat.
We need to calculate the velocity of dog
Using conservation of kinetic energy,
[tex]\dfrac{1}{2}m_{d}v_{d}^2=\dfrac{1}{2}m_{c}v_{c}^2[/tex]
[tex]\dfrac{1}{2}m_{d}(v_{d}+0.91)^2=\dfrac{1}{2}m_{c}v_{c}^2[/tex]
[tex]m_{d}(v_{d}+0.91)^2=0.45m_{d}v_{c}^2[/tex]
[tex]v_{d}+0.91=0.67v_{c}[/tex]
[tex]v_{d}=0.67v_{c}-0.91[/tex]...(II)
From equation (I) and (II)
[tex]0.497v_{c}=0.67v_{c}-0.91[/tex]
[tex]v_{c}=\dfrac{-0.91}{(0.497-0.67)}[/tex]
[tex]v_{c}=5.26\ m/s[/tex]
Put the value in equation (I)
[tex]v_{d}=0.497\times5.26[/tex]
[tex]v_{d}=2.61\ m/s[/tex]
We need to calculate the difference in speed of the dog and cat
Using speed of dog and cat
[tex]v_{c}-v_{d}=5.26-2.61[/tex]
[tex]v_{c}-v_{d}=2.65\ m/s[/tex]
Hence, The difference in speed of the dog and cat is 2.65 m/s
In a standard gas grill propane tank, there is approximately 4,579 mL of propane (C3H8). At a temperature of 55˚C, the tank has a pressure of 1,798 kPa. The tank is cooled to 25˚C and the pressure reduced to 1,025 kPa. What will the new volume be?
Answer:
7300 mL
Explanation:
The question is a bit misleading, since tanks generally have a constant volume. But anyway, using ideal gas law:
PV = nRT
If amount of gas (n) is constant, then:
PV / T = constant
P₁V₁ / T₁ = P₂V₂ / T₂
(1798 kPa) (4579 mL) / (55 + 273) K = (1025 kPa) V / (25 + 273) K
V = 7298 mL
Rounded to two significant figures, the volume is 7300 mL.

What does it mean to say that mass is conserved during a physical change?
Answer:
Alright, so mass is a property of a physical body. During physical changes, such as acceleration, force, etc, the mass stays the same since we are not affecting its physical shape, just where it is physics wise. So yeah mass is conserved during a physical change.
Explanation:
Hopefully this helped, if not HMU and I will get u a better answer
-have a great day! :)
In a physical change the mass remains the same before and after the process, then it is said as the mass is conserved and mass is only conserved in the isolated system.
What is the law of Conservation of Mass?A system that is isolated from its environment is one that does not communicate with it. As a result, no matter what changes or chemical reactions take place in that isolated system, the mass will remain constant; even if the final state may differ from the initial state, there can be no more or less mass than there was before the change or reaction.
The understanding that substances do not actually vanish as a result of a reaction, despite what might appear to be the case, but rather change into another material of equal mass, was made possible by the law of conservation of mass, which was essential to the development of chemistry.

Answer:
Nobody can hear them play.
Explanation:
There is no sound in space.
What’s wrong with this picture is in space it is not possible to hear any sound.
Why is space completely silent?When these waves reach your ears, they are the particles that vibrate in your eardrum for you to hear. So if space is a big vacuum, there are no particles to create sound waves. Therefore, sound cannot propagate if we are floating through the cosmos.
In this way, the irony of the image is given by the musical concert between astronauts that nobody can hear them playing.
