Answer:
t=d
s
120 / 30
6 ossilation per sec
Explanation:
120 oscillation are (d)
and 30 sec is the time and to find
how many ossilation are in 1 sec are 6

Answer:
thetha =2πN = 2*3.14*120 = 753.6
time = 30 sec
angular velocity = thetha/time = 753.6/30 = 25.12
time period = 2π/angular velocity = 0.25 sec
frequency = 1/0.25 = 4 /sec
