Ye sit does. But since people weren’t there to hear it, doesn’t mean that it didn’t make a sound.
Answer:
The force is 
Explanation:
We can apply the following expression
To find the area of rectangular tent wall:
Now to find the force:
<span>node spacing = half of wavelength = 3 cm
velocity = 10 cm/s = freq * wavelength
hench freq = 10/6 = 5/3 = 1.7 hz</span>
Answer:
W = 354.9 J
Explanation:
Given that,
The mass of a bale of hay, m = 23 kg
The displacement, d = 3.9 m
The horizontal force exerted on the hay, F = 91 N
We need to find the work done. We know that,
We know that,
Work done, W = Fd
So,
W = 91 N × 3.9 m
W = 354.9 J
So, the required work done is 354.9 J.
The answer is very similar to the story and occasionally
