To Choose: The correct option.
Answer to Problem 5STP
The correct option is (B).
Explanation of Solution
Introduction:
Frequency is nothing but the number of repeating events in an interval of time. This time interval in one cycle is known as period which is the reciprocal to the frequency.
The expression of frequency can be written as,
Here,
Unit of force is Newton.
Unit of time is nanosecond.
Unit of speed is meter/second.
Therefore, options A),C) and D) are wrong.
But frequency is the number of cycle per second. It can be expressed either per second or hertz.
Thus, the correct option is (B).
Conclusion:
Hence, unit of frequency is (B).
