Q. Two balls are released simultaneously from a certain
1 answer:
Answer:Yes
Explanation:
Time taken for the first ball will depend upon the height of roof. As it is dropped so initial vertical velocity will be zero.
so time taken will be
where h=height of roof
g=acceleration due to gravity
Horizontal velocity is given to second ball so it cover more horizontal distance as compared to first but time taken will be same as it has to cover same vertical distance with zero vertical velocity and time taken depends on height of roof and g.

Explanation:
The period of a wave is equal to the reciprocal of the frequency:
where f is the frequency.
In this problem, f = 262 Hz, so the period if this sound wave is
