4. A wind turbine is 30% efficient. This means that only 30% of the kinetic energy from the wind is turned into electricity. What happens to the other 70% of the energy?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

we need to know the time interval during which the force acts. impulse of force = momentum change

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
