Im thinking D. It is 100 times larger
Answer:B
Explanation:
As you are sitting on the chair, gravity tends to pull you downwards but the normal reaction exerted by the chair is just enough to keep you from falling downwards. It works in the upward direction
The formulas you will need are:
Kinetic energy = (1/2) (mass) (speed)² .
and
Potential energy = (mass) (gravity) (height) .
And of course,
Total energy = constant .
Answer:
Sound energy (that is, mechanical vibrational waves passing through an elastic medium) is a combination of kinetic and potential energies. As the wave compresses the medium (storing elastic potential energy) the medium comes to rest (no motion so no kinetic energy).
Explanation:
Hope this helps :D
