Answer:
Option B
10.36 m/s
Explanation:
Using the first given equation, then velocity=distance/time
Since distance is provided as 200 m and time, t is 19.3 seconds then substituting these figures yields
v=200/19.3=10.3626943
Rounding off to 2 decimal places, then
v=10.36 m/s
Answer:
A time period is denoted by 'T' . It is the time to complete one cycle of vibration. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds
