The load L is lowered by the two pulleys which are fastened together and rotate as a single unit. For the instant represented, drum A has a counterclockwise angular velocity of 3.9 rad/sec, which is decreasing by 6.6 rad/sec each second. Simultaneously, drum B has a clockwise angular velocity of 6.2 rad/sec, which is increasing by 3.3 rad/sec each second. Calculate the accelerations of points C and D and the load L.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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
