A boat is floating in a small pond. the boat then sinks so that it is completely submerged. what happens to the level of the pond?
It increases!
This is an example of conservation of angular momentum.
The ice skater will rotate more slowly because her arms would be considered the outside torque that is impacting her constant angular momentum.
So, an ice-skater who throws her arms out will rotate more slowly.
efficiency= [useful energy transferred ÷ total energy supply]×100%
So, [5500÷10000]×100%=0.55×100
=55%
Answer:
Kinematics is the study of motion.
