If this person has a normal 8.00% ability to accommodate (increase) the power of his eyes, what is the maximum distance of objects he can see clearly in m with his contact lenses and with totally relaxed eyes? (Assume a lens-to-retina distance of 2.00 cm. If he can see very distant objects clearly, enter 'infinity'.)

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

What are the theoretical properties of a gas at a temperature of 0 kelvin?

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?
