Explanation:
The time must be measured with respect to gravity. As it falls, it has free fall that is the force acting on it will be the gravity.With the distance in account, d = 1/2 gt²
t = √(2d/g)
Answer:
Explanation:
The ratio of apparent frequency and real frequency is 1.06 . Let v be their velocities . According to Doppler formula for source of sound and observer
approaching each other , the formula is as follows
n = n₀ ( V+v ) / (V-v )
Here V is velocity of sound which is 340 m /s
n / n₀ = ( V+v ) / (V-v )
1.08 =
360.4 - 1.06 v = 340 +v
v = 9.9 m /s.
