Abowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. ignore frictional losses and assume that the mass of the ball is distributed uniformly. the translational speed of the ball is 3.50 m/s at the bottom of the rise. find the translational speed at the top. cutnell, john d.; johnson, kenneth w.; young, david; stadler, shane. physics, 10th edition (page 247). wiley. kindle edition.

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

The energy equivalent of the rest mass of an electron is

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
