The vector sum of forces acting on a non-accelerating object equals zero.
equation form: ΣF = 0
Since the two taped poles of the magnets labeled A and B attracts one to each other, we know that the two taped poles are oppsosite.
So, you can predict with total certainty that when she brings the taped end of the third magnet (magnet C) near each of the first two magntes, in one case they will attract each other and in the other case they will repele mutually.
You are certain of that because, since the taped poles of the first two magnets are opposite, the pole of the third magnet has to be equal to one of the two first taped poles and opposite to the other of the two firest taped poles.
Answer: 1 inclined plane and box mover trolley
2 screw and drill
3 The axle, or rod and wheels
4 slides, ramps, and hills.
5 yes because they help the ball move quicker
6 i am not sure about this one)
Explanation:i do not know i am guessing
is the acceleration of the box.
<u>Explanation:</u>
Given data:
Mass of the box = 3.74 kg
Flat friction-less ground is pulled forward by a 4.20 N force at a 50.0 degree angle and pulled back by a 2.25 N force at a 122 degree angle.
First, we need to find the net horizontal force acting on the box. With the given data, the equation can be formed as below. Net horizontal force acting on the box (F) is given by
F = 2.699676 – 1.192275 = 1.507 N
Next, find acceleration of the box using Newton's second law of motion. This states that the link between mass (m) of an objects and the force (F) required to accelerate it. The equation can be given as
