Question

A 11,000-watt radio station transmits at 880 kHz. Determine the number of joules transmitted per second.

11,000
11
880,000
880

Answer 1

1 watt = 1 joules per second

The number would be the same:

11,000 watts = 11,000 joules per second

Answer 2

The number of J/s is 11000.

A is correct option.

Explanation:

Given that,

Power P = 11000 watt

We know that,

Joule :

Joule is the unit of SI system. Joule is the unit of energy.

Energy is the product of power and time.

1 J = 1 N-m

One watt is equal to the one joule per second.

So, the number would be same

11000 watt = 11000 J/s

Hence, The number of J/s is 11000.
