Sigh someone stole the points and it marked as an answer so please someone actually answer this. A 65 kg swimmer jumps off a 10 m tower.

Find the swimmer's velocity on hitting the water.

The swimmer comes to a stop 2 m below the surface. Find the net force exerted by the water.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
