Explain why for thousands of years people believed that
stars moved across Earth’s sky. Explain why we now have a different explanation of why
stars move across the night sky. Be sure to mention reference points.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

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

it is b. absorbs thermal energy
