What is the frequency of the second hand of a clock, assuming it is keeping correct time?
Select one:
a. 1 Hz
b. π/3 Hz
c. 0.0167 Hz
d. 60 Hz
Second hand = 1 rpm:
1/60 rps; i.e. 1/60 cycle/s; i.e. 1/60 Hz
The second hand is the minutes hand. 1 revolution is = to one min so 60 seconds. Frequency is equal to 1/T where T is the period, in other word the time it takes to make one full revolution. so f= 1/60 = 0.0167
Well, the frequency of the second hand of a clock would actually be d. 60 Hz, if we're talking about a regular analog clock. Although, you have to admit, it's pretty impressive that a tiny hand can complete a full rotation 60 times in just a minute. That would make for quite the dizzying dance party!
To determine the frequency of the second hand of a clock, we need to understand what frequency means in this context. Frequency refers to the number of cycles or vibrations that occur in a given unit of time. In the case of the second hand of a clock, the cycle is completed every minute, as it takes 60 seconds for the second hand to make a full rotation.
To calculate the frequency, we need to determine how many cycles occur in one second. Since there are 60 seconds in a minute, and the second hand completes one full cycle in a minute, we can divide 1 minute by 60 seconds to find the number of cycles in one second.
So, the frequency of the second hand of a clock is:
1 cycle / 60 seconds = 1/60 cycles/second
Therefore, the correct answer is c. 0.0167 Hz.
