10^6Hz
The transmit power is: P = 20kW = 20 X 10^3 W
The transmit power is: h = 6.63 x 10 ^-34 m^2.kg/s
The number of photon emitted per second = N = P/hf = <u>30.16 x 10^30 </u>photon/s.

Explanation:
Horsepower is related to watt as: 1 horsepower = 746 W = 750 W approximately. 1 horsepower (HP) = 750 watt (approx.) The power is one watt when one joule of work is done in one second.
Answer:
14.7 J
Explanation:
PE=MGH
PE= 1.0 x 9.8 x 1.5 = 14.7 J
For radio broadcasting, in electricity meters, in any generator.
Show me the graphs and i would be glad to help u
