Answer:
10.116 Pounds/45 newtons = 10.1164024 pounds/force
Explanation:
Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg
Answer:
This question is incomplete, a possible question would be to calculate the work done by the ball.
Work done = 8J
Explanation:
Work done by an object is calculated my multiplying the force by the distance.
The weight of this ball is 2.0N, which also represents the force exerted by the ball. The ball travels through a distance of 4m
Hence, work done = F × d
Work done = 2N × 4m
Work done = 8Nm or 8J
From Snell's Law;
n₁sinθ₁ =n₂sinθ₂
Therefore; since the ray is travelling from ethanol to air, then n1 = 1.36 and
θ1 = 34, while n2= 1.00
(1.36) sin 34 = (1.00) sin θ₂
sin θ₂ = 0.7605
θ₂ = 49.50
≈ 49 °
The angle of refraction is therefore 49 degrees
