Which statement about gravity is written as a law? *
1 point
a the reason gravity works is because masses bend time and space.
b the effect of gravity on plants might be reduced if certain minerals are added to the soil.
c the force of gravity between two objects depends upon their masses and the distance between them.
d the experiments being done on gravity today are better than what were done in the past and a full understanding is only a few years away.

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.)
