Answer:
Medium 1 is air and Medium 2 is water because the light slows down.
Explanation:
Light is known to slow down in water since water is denser than air.
You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.
Answer:
50.0543248872 ft
Explanation:
F = Load = 20 ton =
d = Diameter = 1.25 in
= Initial length = 50 ft
= Final length
A = Area =
Y = Young's modulus =
Young's modulus is given by
The length during the lift is 50.0543248872 ft
