The velocity with which will move the body when released from height of 500m is 100m/s
How to calculate velocity?The vertical acceleration is known to be a constant g.
d^2y/dt^2=−g
After integrating, we'll refer to our constant as v0.
dy/dt=v0−gt
That's our time-dependent vertical velocity. In our situation, the starting velocity v0=0, implying that we began at rest at time t=0.
dy/dt=−gt
Let us integrate once more, with the integration constant. y0.\s
y=y0−1/2gt^2
We have
y0=500 and want t when y=0.
2=1000
t=√1000g
We frequently employ the assumption g=10m/s2, which yields t=10
At t=10t=10, how fast is it moving?
dy/dt=−gt=−(10)(10)=−100

a 1.0 kg chunk of putty moving at 1.0 m/s collides and sticks to a 5.0 kg bowling ball that is initially at rest. What is the magnitude of the momentum of the ball and putty after the collision
The magnitude of the momentum after the collision between the ball and the putty is 0.167 m/s
Following the two balls collided, our task is to determine the velocities of the first and second balls after the impact. In order to complete this, we can apply the law of the conservation of momentum, which states that the total momentum before the collision must be equal to the momentum after the contact. In this case, we are given that:
Mass of the first ball (m1) = 1 kg
Mass of the second ball (m2) = 5 kg
Initial velocity of the first ball (v1) = 1 m/s
Initial velocity of the second ball (v2) = 0 m/s
To calculate the final magnitude of momentum, we can use this following formula:
m1 v1 + m2 v2 = (m1 + m2) v
1 kg x 1 m/s + 5 kg x 0 m/s = (1 kg + 5 kg) v
v = 0.167 m/s
Thus, the final magnitude of the momentum would be 0.167 m/s

how tall (in cm) would such a manometer have to be to measure blood pressures as high as 190 mm hg?
The tall of the manometer when blood pressure is 190 mm Hg is 103.17 cm
To find fluid hydrostatic pressure, we can use the following equation :
P = ρgh
Where :
P is pressure of fluidρ is density of fluidg is gravity accelerationh is depth of fluidFrom the question, there are 2 information and assumption :
1. Height of mercury = 190 mm Hg
2. Since the manometer liquid is not clear, assume that the manometer was filled with water
Both water and mercury have the same hydrostatic pressure. So the equation will be :
ρw . g . hw= ρHg . g . hHg
Since both water and mercury have the same g, we can cancel the g. The equation will become :
ρw . hw=ρHg . hHg
hw = ρHg . hHg / ρw
As known, below is the density for both liquid
Density of mercury = 5.43 g/cm³
Density of water = 1 g/cm3
So we can start to find the tall height of water filled manometer by solving the equation
hw = (190 mm) x (5.43 g/cm3) / (1 g/cm3)
= 1031.7 mm

Find the electric potential difference across lamp 1 if the source has an electric potential difference of 10.9 V, and the electric potential difference across lamp 2 is 4.8 V and lamp 3 is 4.8 V
Answer:
1.5v
Explanation:
To find the electric potential difference across lamp 1, you will need to know the resistances of the lamps and the current flowing through the circuit. The electric potential difference across each lamp is equal to the current flowing through the lamp multiplied by the resistance of the lamp.
You can use Ohm's law to calculate the current flowing through the circuit. Ohm's law states that the current flowing through a conductor is equal to the electric potential difference across the conductor divided by the resistance of the conductor.
Once you have calculated the current, you can use the electric potential difference equation (voltage = current * resistance) to find the electric potential difference across each lamp.
Alternatively, you can use Kirchhoff's voltage law to solve for the electric potential difference across each lamp. Kirchhoff's voltage law states that the sum of the electric potential differences across all of the elements in a circuit is equal to the electric potential difference of the source. So, if the electric potential difference across lamps 2 and 3 is 4.8 V each, and the electric potential difference of the source is 10.9 V, then the electric potential difference across lamp 1 must be 1.5 V.

544) monochromatic infrared waves with a wavelength of 750 nm pass through 2 narrow slits. if the slits are 25 um apart, at what angle will the fourth order bright fringe appear on a viewing screen ?
The angle at which the fourth order bright fringe appear on a viewing screen is 6.89°. If the wavelength is 750nm and distance between the two slits is 25um.
What is bright fringe?When the crest of a light wave coincides with the crest of another light wave then that interference is called as the bright fringe. The same thing happens with the dark fringe of light wave also, when the trough of one wave coincides with the trough of another wave then this results in the formation of dark fringes.
The angle of the bright fringe appear on a viewing screen can be calculated with the help of a formula:
sinθ = mλ/ d
where, θ = angle of bright fringe,
m = number of bright fringe,
λ = wavelength of the light wave,
d = distance between the two slits
sinθ = 4 × 750 × 10⁻⁹/ 25 × 10⁻⁶ = 0.12
θ = 6.89°
Therefore, the angle at which the fourth order bright fringe appear on a viewing screen is 6.89°.

The current in r2 is -1.25 A, found by using Ohm's law.
B. To find the current in r2, we can use Ohm's law, which states that the current flowing through a resistor is equal to the voltage across the resistor divided by the resistance. In this case, we are given that the voltage across r2 is 28 V and the resistance is 8ω.

What is the acceleration of the car?The acceleration of the car is determined by applying Newton's second law of motion as shown below.
Mathematically, the formula for Newton's second law of motion is given as;
F (net) = ma
where;
m is the mass of the cara is the acceleration of the carThe net force acting on the car is calculated as follows;
F (net) = F - Ff
where;
F is the applied forceFf is the force of frictionF (net) = 38,900 N - 34,000 N
F (net) = 4,900 N
The acceleration of the car is calculated as follows;
a = F (net) / m
a = ( 4,900 N ) / ( 745 kg )
a = 6.58 m/s²
The time of motion of the car is calculated as follows;
v = u + at
v = 0 + at
v = at
t = v / a
t = ( 21 m/s ) / ( 6.58 m/s² )
t = 3.2 s

If it were not for the inclination of Earth's axis, there would be no well-defined seasons.
True
False
The statement, "if it were not for the inclination of earth's axis, there would be no well-defined seasons." is true.
How season is connected with Orbit?Many people think that the July heat is brought on by Earth's close proximity to the Sun. They also believe that during the winter, Earth is furthest distant from the Sun. It is untrue. The Earth's orbit is not a complete circle, it is true. It is somewhat disproportionate. The Earth and Sun get closer to one another at different times during the year.
Nevertheless, there are winter and summer seasons in the Northern Hemisphere, with winter being the season when Earth is closest to the Sun. The imaginary pole known as the Earth's axis runs through the planet's center from "top" to "bottom." The planet circles fully around this pole every day. The seasons on Earth are impacted by the planet's tilt.

In an epinephrine-triggered signal transduction pathway, how would cellular response most likely be affected if epinephrine could not bind with the receptor protein?.
G proteins would continue to be inactive, preventing signal amplification.
What causes certain cells to react to the ligand adrenaline while not others do?Epinephrine receptors are not present in all cells. Only cells that have these receptors may react. Signal transduction may lead to modifications in gene expression and cellular operation, which may modify an embryo's phenotype.
By modifying the creation of proteins and enzymes, changes in signal transduction pathways change cellular responsiveness and have an impact on procedures such the binding of messenger molecules to receptors.
Protein kinase A is activated by cAMP's binding to it, allowing PKA to phosphorylate subsequent components and trigger a physiological response.

An object starts from rest and has an acceleration of 2.0 ms−2. What is the speed (v = at) of the object after 7.00 seconds with the correct number of significant digits?
Answer:
14 m/s
Explanation:
Correct number of sig dig will be two since accel has only two SD ( you can only have as many SD as the factor with the LEAST SD)
v = at
= 2 m/s^2 * 7 s = 14 m/s
