Question

A 10,000-watt radio station transmits at 535 kHz.

Determine the number of joules transmitted per second.

Answer 1

If you are given a 10,000-watt radio station transmits at 535 kHz, then you just divide one by 535,000 Hz which is equal to 1.87 x 10^-6 seconds. Multiply this value by 10,000W and you get 0.019 Joules.

Answer 2

Answer:

Energy is 10,000 Joules.

Explanation:

It is given that, a 10,000 watt radio station transmits at 535 kHz. We have to write the number of joules transmitted per second.

We know that number of joules transmitted per second is called the power. Its SI unit is watts. Mathematically, the power of radio station is given by :

$P=\dfrac{W}{t}$

Where

W is the work done by radio station

t is the time taken.

According to relation :

$1\ watt==\dfrac{1\ Joule}{1\ seconds}$

So, $10,000\ watt==\dfrac{10,000\ Joule}{1\ seconds}$

Hence, energy per second is 10,000 Joules.
