The continental crust is than the oceanic crust and seems to "float" on the mantle.
a) thinner
b) younger
c) less dense
d) mostly basalt

c

Explanation:

The continental crust is much older than oceanic crust. It is also less dense than the oceanic crust and seems to float on Earth's mantle.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
