The final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration
Answer:
Explanation:
Potential energy, which is the energy a body assumes at a position, can be calculated using the formula:
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (m)
Answer:
If a body is electrically neutral it means it has no net charge.
Explanation:
Because it has the same number if protons as it does electron , which are opposite charges that offset eachother.
Answer:
Loudness of the second sound is more than the first one.
Explanation:
There are two sounds, the second sound is identical to first but the loudness of second is more than the first one.
As the frequency is same so the itch is same for both the sounds.
As the loudness depends on the amplitude of the sound so the loudness of the second sound is more than the first sound.
