a)2.5 s
b)3 s
c)45 s
d)15 s​

Answer 1

Answer:

3s

Explanation:

time period = time taken/no of cycles

= 45/15 = 3s

please please mark as brainliest

Answer 2

Answer:

b) 3s

Explanation:

the time period is the amount of time taken by oscillation

so to find that out we have to divide the time taken by the oscillation

so

time taken/no.of oscillation =45

seconds/15oscilation

= 3 seconds
