Question

I do not know how to figure out these problems. Please help.

a. Find the period of the second hand of a wall clock. (units in seconds)

b. Find the frequency of the second hand of a wall clock. (units in Hz)

c. Find the angular frequency of the second hand of a wall clock. (units in rad/s)

d. Find the period of the minute hand of a wall clock. (units in seconds)

e. Find the frequency of the minute hand of a wall clock. (units in Hz)

f. Find the angular frequency of the minute hand of a wall clock. (units in rad/s)

if possible please show me steps. Thank you

Explanation / Answer

a)period of second hand(T)=60sec*(1min/60sec)=1min/revolution b)Frequency of second hand=1/T= 1revolution perminute c)angular frequency of the second hand = (2*pi)/60 rad/sec d)period of minute hand = 60min=60min/revolution e)frequency of minute hand= 1/60 RPM=1/3600 hertz f) angular frequency of the minute hand= (2*pi)/360rad/sec
