The crest of the wave has traveled 415 cm in 11.7s. then the crest should have travelled 415/11.7 cm in one second i.e. 35.47cm. Then the crest should have travelled 26*35.47 cm in 26 seconds i.e. 922.2cm which has 46 vibrations in it.
so for length of each vibration (Wavelength) is 20 cm
Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.
Answer:
v = 66.7 m/s
Explanation:
Given that,
The length of steel cable, L = 600 m
Diameter = 1.2 cm
It is observed that it took 18 s for the pulse to return.
The time taken to cover 600 m will be :
t = T/2
t = 9 s
Let v be the of the pulse. We know that,
So, the speed of the pulse is equal to 66.7 m/s.
