"energy above that needed to ionize the molecule is carried away as kinetic energy of the electron ejected"
A raised weight.
Water that is behind a dam.
Those are all some potential and kinetic
A car that is parked at the top of a hill.
Explanation:
I’d say d

The answer is <span>Energy is released in the reaction.</span>
In order to answer either of these, we need to know the energy content of coal ... like kwh (or joules or BTU) in each kilogram (or pound or ton) of coal.

<u>Option</u><u> </u><u>A</u><u>:</u><u> </u><u>1</u><u>9</u><u>.</u><u>5</u><u> </u><u>W</u></h3>
Power of TV = 65Watt
If Efficiency = 70%, then the percentage of energy wasted is 30%
So, the amount of energy getting wasted:
= 30/100 × 65
= 1950/100
= 195/10
= 19.5 W
