What is the threshold frequency ν0 of cesium?

A student, starting from rest, slides down a water slide. on the way down, a kinetic frictional force (a nonconservative force) acts on her. the student has a mass of 76 kg, and the height of the water slide is 12.8 m.

A high diver leaves the end of a 5.0 m high diving board and strikes the water 1.5 s later, 2.4 m beyond the end of the board. considering the diver as a particle, determine the initial velocity

To convert from meters per second to kilometers per second you need only to divide by 1000

According to the kinetic-molecular theory, gases condense into liquids because of
