Answer:

Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

A ball has a mass of 4.65 kg and approximates a ping pong ball of mass 0.060 kg that is at rest by striking it in an elastic col

castortr0y [4]

Answer:

the final velocity of the ball is 4.87 m/s

the final velocity of the ping ball is 9.87 m/s

Explanation:

Given;

mass of the ball, m₁ = 4.65 kg

mass of the ping ball, m₂ = 0.06 kg

initial velocity of the ping ball, u₂ = 0

initial velocity of the ball, u₁ = 5 m/s

let the final velocity of the ball = v₁

let the final velocity of the ping ball, = v₂

Apply the principle of conservation of linear momentum for elastic collision;

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

4.65(5) + 0.06(0) = 4.65v₁ + 0.06v₂

23.25 + 0 = 4.65v₁ + 0.06v₂

23.25 = 4.65v₁ + 0.06v₂ ------ (1)

Apply one-directional velocity equation;

u₁ + v₁ = u₂ + v₂

5 + v₁ = 0 + v₂

5 + v₁ = v₂

v₁ = v₂ - 5 -------- (2)

substitute equation (2) into (1)

23.25 = 4.65(v₂ - 5) + 0.06v₂

23.25 = 4.65v₂ - 23.25 + 0.06v₂

46.5 = 4.71 v₂

v₂ = 46.5/4.71

v₂ = 9.87 m/s

v₁ = v₂ - 5

v₁ = 9.87 - 5

v₁ = 4.87 m/s

Think of air pressure as a column of air. At what altitude do you think air pressure is the highest? _________________

AnnZ [28]

Answer:

lowest: 30km (and above)

highest: sea level

Explanation:

1/ As we are talking about the air, so the lowest altitude is the sea level (Zero mile) - the air pressure P = 1 atm

2/ Since more than half of the atmosphere's molecules are located below an altitude of 5.5km, atmospheric pressure decreases roughly 50% (to around 500mb) within the lowest 5.5km. Above 5.5km, the pressure continues to decrease but at an increasingly slower rate.

And as you can see in the picture attached below, the lowest value of air pressure is reached at the altitude about 30km (about 20miles).
