Question

A person measures the depth of a well by measuring the time interval between dropping a stone and
receiving the sound of impact with the bottom of the well. The error in his measurement of time is
δT = 0.01 seconds and he measures the depth of the well to be L = 20 meters. Take the acceleration due to
gravity g = 10 ms⁻² and the velocity of sound is 300 ms⁻¹ . Then the fractional error in the measurement,
δL/L, is closest to
[A] 0.2 % [B] 1 %
[C] 3 % [D] 5 %

Answer 1

Answer:

In this way we can solve the problem my friend
