Hello There!
-Energy Is The Ability To Do Work-
Energy comes into different forms but they can all be placed in two different categories. These categories are "potential" which means stored energy and energy of position and "kinetic" which is the energy of motion.
POTENTIAL ENERGY <em>Stored energy and the energy of position</em>
CHEMICAL ENERGY <em>Energy in the bonds of atoms and molecules</em>
MECHANICAL ENERGY <em>Energy stored in objects by tension</em>
NUCLEAR ENERGY <em>Energy stored in the nucleus of an atom</em>
GRAVITATIONAL <em>Energy that is stored in an object's height</em>
ELECTRICAL ENERGY <em>Delivered by tiny charged particles called electrons</em>
KINETIC ENERY <em>The energy of motion</em>
THERMAL ENERGY <em>The vibration and movement of atoms and molecules in substances.</em>
RADIANT ENERGY<em> </em><em>Electromagnetic energy that travels in waves</em>

Explanation:
The power of an object is given by :
Here,
E is the energy required
t is time
The SI unit of power is Watts and the SI unit of energy is Joule. the commercial unit of energy is kilowatt per hour.
Option (1) : A kilojoule (kJ) is a unit of power is incorrect.
Option (2) : A gigawatt (GW) is a unit of energy is incorrect.
Option (3) : A watt (W) is a unit of energy is incorrect.
Option (4) : A kilowatt x hour per year (kWh/yr) is a unit of energy is incorrect.
Option (4) : A kilowatt (kW) is a unit of power is correct.
Hence, the correct option is (d).
Explanation:
Solution,
Volume (v)=287 cm^3
Mass(m)=816 g
Density(d)=m/v
=816/287
=2.84
So, the density of the block of marbles is 2.84 g/cm^3.
