Newton's Third Law of Motion states that for every action there must exist an equal but opposite reaction.

This ultimately implies that, Newton's Third Law of Motion is a law based on action-reaction force pairs.

In this exercise, you're required to identify the action-reaction forces in the attached picture.

Under condition A, a boy is leaning against a wall;

  • The force being exerted by the boy on the wall is a force of action.
  • The force being exerted by the wall on the boy is a force of reaction.

Under condition B, a boy is jumping off a diving board.

  • The force being exerted by the feet of the boy on the diving board is a force of action.
  • The force being exerted by the diving board on the feet of the boy is a force of reaction.

Under condition C, a nail is being hammered into the wall.

  • The force being exerted by the hammer on the nail is a force of action.
  • The force being exerted by the nail on the hammer is a force of reaction.

Under condition D, a man is walking on a ground (floor).

  • The force being exerted by the foot of the man on the ground (floor) is a force of action.
  • The force being exerted by the ground (floor) on the foot of the man is a force of reaction.

Under condition E, a boy is holding a ball;

  • The force being exerted by the hand of the boy on the ball is a force of action.
  • The force being exerted by the ball on the hand of the boy is a force of reaction.

2 Magnetism comes from the word
AysviL [449]

Answer:

A Magnesia

Explanation:

The word magnetism comes from the word Magnesia, which is the name for a region in Asia Minor, where fragments of Fe3O4 ore (magnetite) were found, which attracts other metal objects.

Magnetism is a physical phenomenon by which we describe the attractive or repulsive force between materials.

This phenomenon has been known for thousands of years.

Complete the steps for converting 3.6 gallons per minute to milliliters per second. (1 gallon = 3.79 liters and 1 liter = 1,000
AlekseyPX

Given that,

Capacity = 3.6 gallons per minutes

Convert it into milliliters per seconds

Since, 1 gallon = 3.79 liters

1 liters = 1000 milliliters

Capacity= (3.6*3.79*1000)/(60)

Capacity = 227.4 milliliters per second.

Terry dropped a pebble from the top of his apartment building. The pebble impacted the ground after falling for 2.2 seconds. Cal
Contact [7]

The final velocity of the pebble as it hits the ground is 21.5 m/s.

We have to use the equation;

v = u + gt

Where;

v = final velocity

u = initial velocity

g = acceleration due to gravity

t = time

Since the pebble was dropped from a height, u =0 m/s, hence,

v = gt

v = 9.8 ms-2 × 2.2 s

v = 21.5 m/s

Someone please help with these 2
Ann [662]

Answer:

Explanation:

The formula that you are working with is F = m*a

Since mass is one part of the formula if you increase the mass, you are going to increase the force.

The second one is much more difficult to answer because it is basically incomplete. This is one way to interpret it. If you start at a certain speed and increase during a known time period then effectively you are defining acceleration which is "a" in the formula.

Without those modifications, there is no answer.
