Since energy can neither be created nor destroyed and it just changes from one form to another...so...
A.
Energy is neither lost nor gained as electrical energy is transformed into the energy of sound.
Answer:
A
Explanation:
I only think its A because of the gravity part...sorry im not good at explaining
Answer:
It will cause kinetic energy to increase.
Explanation:
Given that Speed and Motion you went from the starting line to the finish line at different rates.
If you repeated the activity while carrying weights but keeping your times the same, the weight carried will add up to the mass of the body.
And since Kinetic energy K.E = 1/2mv^2
Increase in the mass of the body will definitely make the kinetic energy of the body to increase.
Since the time is the same, that means the speed V is the same.
Weight W = mg
m = W/g
The new kinetic energy will be:
K.E = 1/2(M + m)v^2
This means that there will be increase in kinetic energy.
When water evaporates of your body it cools you down, hence why after a shower when the water droplets begin to evaporate you feel cold
