Positive. The 1st object loses electrons and will thus have an imbalance of charge with loss of electrons.
The correct option is C.
When the temperature of an object that is giving off light is increased, the particles in the object will move at a faster rate and there will be increased vibration of these molecules. This will makes the object to emit more light and to shine more brightly. Thus, the higher the temperature, the brighter the light that will be emitted.
Power = (voltage) x (current)
Power = (120) x (8) = 960 watts = <em>0.960 kilowatt</em>
By definition, average acceleration will be:
a=(v(f)-v(i))/t
a=(2-14)/6=-2 (m/s^2)
________
-2(m/s^2)
