Mass is the physical quantity
Answer:
The tension on each rope is 28.28 lb
Explanation:
Given that,
Weight = 40 lb
Angle = 45°
We need to calculate the tension on each rope
Considering the symmetry of the system, the tension of each rope must be same
So,
Put the value into the formula
Hence, The tension on each rope is 28.28 lb.
Answer:
It increases by four times the initial amplitude.
Explanation:
The amplitude of a sounde is inversely proportional to the square of the distance between the listener and the sound source:
In this problem, the distance is decreased to hald the initial distance, so we can write
therefore, the new amplitude will be
So, the amplitude increases by a factor 4.
