Answer:
frequency = 1
time period = 1
Explanation
total number of complete oscillation = 90
total number of seconds = 90
To take out frequency formula
Frequency = No of vibration / seconds
therefore, frequency = 90 / 90
which is equal to 1
hence, frequency = 1
to take out time period formula
time period = 1 / frequency
therefore , time period = 1 / 1
which is equals to 1
hence, time period = 1
