An aquarium 6 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

A plastic tube allows a flow of 15.9 cm3 / s of water through it. how long will it take to fill a 237 cm3 bottle with water? answer in units of s.

How does surface tension relate to the molecular structure of water

A ray of light is incident on an unknown transparent substance from of incidence is 40°, and the angle of refraction is 22° (a) Explain why these measurements indicate that a change in speed must be happening as the light changes medium.

Identify the correct order of increasing intermolecular force of attraction for the three most common states of matter. A) liquid - solid - gas B) Solid - liquid - gas C) gas - liquid - solid D) gas - solid - liquid

A 20.5 kg box initially at rest is pushed 5.93 m along a rough, horizontal floor with a constant applied horizontal force of 95.3501 N. If the coefficient of friction between box and floor is 0.389, find the work done by the applied force.

Some people refer to nuclear power as "clean energy." Why do they make this argument? Do you agree or disagree? Explain your answer.

What does thermal energy mean?

Oil having a density of 924 kg/m 3 floats on water. A rectangular block of wood 3.79 cm high and with a density of 970 kg/m3 floats partly in the oil and partly in the water. The oil completely covers the block.

Where does the energy that is used to ride a bicycle up a hill come from and how is it classified?

Explain how the energy of a rubber ball is transformed as it rolls down a ramp.
