Answer
-The magnitude of acceleration during the fall is greater
Answer:
Percentage change in tension is 3.8%
Explanation:
We have given initially frequency = 440 Hz
Let tension in the string at this frequency is
Now second frequency is
Frequency in string is given by
From the relation we can say that
Percentage change in tension is equal to
%
So percentage change in tension is 3.8%
Answer:
0.75 second
Explanation:
The equation is
Let t be the time when it is at 73 feet. Substitute, h = 73 in the above equation and then find the value of t.
Take positive sign
t = 0.75 second
