Suppose you place a coin on a book; the book’s cover acts as a ramp. You open the cover slowly until static friction is overcome. The coin begins to slide. What happens to the forces on the coin as the angle of the cover changes? Select all correct answers. a. A component of the frictional force begins pushing the coin and book together. b. The frictional force decreases suddenly as the coin starts to slide. c. The gravitational force increases. d. The component of gravitational force along the surface increases. e. The component of gravitational force perpendicular to the surface decreases. f. The normal force decreases slowly, which produces a slow decrease in static friction.

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.)
