Answer:
W = 600 J
Explanation:
We have,
According to attached figure,
Height of the inclined plane is 60 m
Force acting on the block is 10 N
It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :
W = mgh
or

So, the work done against the gravity is 600 J.
Answer:
longitudinal wave
Explanation:
it is perpendicular to the direction of the wave
F=ma
F = 148×(85-35)÷20
F = 148×(50÷20)
F = 148×2.5
F = 370N
The answer I found was parabola?
