Nolan is making a capacitor using plates that have an area
of 3.2 x 10-4 m2 separated by a distance of 0.20 mm. He
has the two dielectrics listed in the table.
At a voltage of 1.5 V, how much more charge can No
store in the capacitor using dielectric 1 than he could
using dielectric 2?
7.5 10-11 C
9.6 x 10-11 c
1.1 10-10 C
1.4 x 10-10 c

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.)
