Answer:

A.Faster than

Explanation:

Due to the Doppler effect which states that there is a change in frequency because of the relative speeds of two bodies time dilation takes place. For light the relative difference in velocity between the observer and the source needs to be considered.

Time dilation is the phenomenon where time flows differently for two bodies having different to each other. Time dilation has been verified by the readings of the satellite navigation systems.

\Delta t'=\frac{\Delta t}{\sqrt{1-\frac{v^2}{c^2}}}

Where

Δt' = Time elapsed of a moving body

Δt = Time elapsed when the body is stationary

v = Velocity of the moving body

c = Speed of light

As, v is always less than c, Δt' will always be greater than Δt. This means that more time has elapsed for the body in motion.

Hence, the clock in motion will be faster than an identical clock at rest.

Using the formula F = M* A. What is the acceleration of a .5 kg
Katyanochek1 [597]

Answer:32 m/s/s

Explanation: since F=M*A, F=16N, M=0.5kg, A= F/M

A=16/0.5

A=32 m/s/s

A small metal bar whose initial temperature was 20 degrees Celsius is dropped into a large container of boiling water. How long
Vesnalui [34]
Below is the answer. I hope it help.
T ( t ) = C e k t + T m where Tm is the temperature of the surroundings 
T ( t ) = C e k t + T m
T ( 0 ) = 20
T ( 1 ) = T ( 0 ) + 2 = 22
C + T m = 20 C+Tm=20 
C e k + T m = 22

A grey hound can run about 40/mph is it velocity,acceleration, or speed
loris [4]

Answer: Speed

Explanation:

Speed is the time it takes something to travel a certain distance. Accelaration is the rate at which an object's speed changes. Velocity is a vector of the object's speed and direction.

Newton's _____law states that when one object exerts a force on a second object, the second object always exerts a force back on
Nina [5.8K]
<h2>Answer:Third</h2>

Explanation:

Newton's third law states that every action force has a equal and opposite reaction force.

Example 1:

Consider yourself hitting a wall with your hand,you are exerting a force on the wall but still you feel hurt because the wall exerts same force on your hand in opposite reaction.

Example 2:

Consider yourself standing on ground.You are exerting force on ground.But how are you able to stand on ground even if your mass is forcing you to go down?The answer is normal reaction force.The ground exerts a force on your feet which makes you to stand still.
