90 grams of liquid water are in a cylinder with a piston maintaining 1 atm (101325 pa) of pressure. it is exactly at the boiling point of water, 373.15 k. we then add heat to boil the water, converting it all to vapor. the molecular weight of water is 18 g/mol and the latent heat of vaporization is 2260 j/g.

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared
