Answer:
C
Explanation:
Radiant= list onto solar panels, Electric= solar into power, Radiant= Electric into light
Answer:

Explanation:
Moment of inertia of given shell
where
M represent sphere mass
R -sphere radius
we know linear speed is given as 
translational 
rotational 
total kinetic energy will be


fraction of rotaional to total K.E

The same amount of work being done over a long period of time!
The mechanical efficiency = actual work / ideal work
So ζ = 1540 / 1600 * 100% = 96.25%
