Answer:
- (a). Frequency = 50 Hz
- (b). Time Period = 0.02 s
Step-by-step explanation:
Given:
- An object completes 1500 vibrations in 30s.
To Find:
- (a) Frequency
- (b) Time Period
Solution:
- Number of vibrations in 30s = 1500
- Number of vibrations in 1s = 1500/30
- Number of vibrations in 1s = 150/3
- Number of vibrations in 1s = 50 Hz
After that,
- Time taken for 1500 vibrations = 30s
- Time taken for 1 vibration = 30/1500
- Time taken for 1 vibration = 3/150
- Time taken for 1 vibration = 0.02 s
Alternative method,
- Time period = 1/frequency
- Time period = 1/50
- Time period = 0.02 s
