Answer:
A) heat
Explanation:
As kinetic energy increases, so does the heat energy produced. The faster the molecules move, the more heat that is generated.
Buoyancy from water. Buoyancy is an upward force on an object immersed in a fluid (i.e., a liquid or a gas), enabling it to float or at least to appear lighter.
I use the impulse momentum formula.
the 4.0 kilogram ball requires more force to stop
Answer:
D
Explanation:
The gravity is pushing the water downward so Wayne could go down but the water is pushing Wayne to go up which would make him float.
