Answer:
It is
Explanation:
1 Answer. The volume is 37.0 cm3Au .
Answer:
8m/s
Explanation:
Average Speed = distance / time = 400/50 = 8m/s
Answer: Constructive interference
Explanation: Just took the test
Let the observer be 'd' distance away from the thunderstorm and let light take 't' time to reach the observer
Since the speed of sound and light remains constant in a particular medium, we can use
Speed = Distance/Time
For light,
3 x 10^8 = d/t
t = d/(3 x 10^8) -1
For sound,
339 = d/(t + 30) -2
Putting value from 1 in 2.
d = 10^4 m(approx)
