The volume of a sphere is increasing at a rate of 25\pi25π25, pi cubic meters per hour. at a certain instant, the volume is \dfrac{32\pi}{3} 3 32π start fraction, 32, pi, divided by, 3, end fraction cubic meters.

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f
