The hammer of an electric bell strikes 1440 times in a minute and does a work of 0.2 J per strike. what is the power of hammer i
n S.I.system?
2 answers:
First we need to convert the frequency to the correct SI units (seconds)
Frequency of bell = 1440/60 = 24 Hertz (Strikes per second)
Power is the rate of work being done or the work done per second.
P = E/t = (24 * 0.2)/1 = 4.8 Watt
