The period of a wave is found to be 50 seconds. What is the frequency of the wave?

Answers

Frequency is the inverse of the time period. The frequency of the wave will be 0.02.

What is the frequency?

Frequency is defined as the number of cycles per second. The time to make one complete cycle is frequency.

Frequency = 1 / period

F=  1 / T

F=1/50 sec

F=0.02 Hz.

Hence, the frequency of the wave will be 0.02.          

To learn more about frequency refer to:

If you remember this one rule, then you can always convert
in either direction between frequency and period.

           (Frequency) times (Period)  =  1 .

So Frequency = 1 / period

                         =  1 / (50 seconds)

                         =  (1/50) per second

                         =   0.02 per second

                         =  0.02 Hertz

True of false efficiency compared the output work to the output force

Answers

The statement about "efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.

A current of 4A flows in a wire of resistance 60 ohm. calculate electrical energy consumed in 2 min.

Answers

Power dissipated = energy/second= (current)² x (resistance)

Power dissipated = energy / second = (4)² x (60) = 960 joules per second= 960 watts

Energy = (power) x (time) = (960 watts) x (2 minutes) x (60 sec/minute)

                 = 115,200 joules
