Hint: In this question think of the quantity whose SI unit is watt, then since we have to comment upon the unit Watt sec thus use that the SI unit of time is sec. Collaborate both these concepts to get the desired quantity.
Complete Step-by-Step solution:
As we know that the unit of power (p) is watt, and when we multiply the power with time it will convert into energy consumed by any respective equipment in that time.
So if we measured the time in seconds the unit of energy is watt-sec, if we measured the time in hour the unit of energy is watt-hour.
And if we measured power in KW.
So the unit of energy is KWh which is the standard unit of energy.
All are the correct units of energy.
So watt sec represents the unit of energy.
For example 500 W equipment runs for 30 sec so the energy consumed by that equipment in 20 sec is
Watt-sec.
And the unit of force is Newton (N).
So this is the required answer.
Hence this is the required answer.
Note – SI units is known as international systems of units, it is a system of physical units based upon the meter, kilogram, second, ampere, kelvin, candela and mole together with a set of prefixes to indicate the multiplication or division by a power of 10.
