<span>The only thing that can change the motion of an object is a net (unbalanced)</span>force acting on it. This is given by Newton's First Law of Motion, sometimes <span>also called the Law of Inertia.

Get a new one and use the new one because the tape might break.
Answer:
The magnitude of the frictional force is
Explanation:
From the question we are told that
The force exerted on the box is
Generally for the box to remain at rest then it means that the frictional force is greater than or equal to the force applied to move it i.e
=>
Answer:
m = 500 grams
Explanation:
Assuming that the fulcrum is at the midpoint of a uniform meter stick, the moments about the fulcrum must be equal and opposite.
the 200 g mass makes a moment
200(g)[20] = 4000g gm•cm
the other mass must also create a moment of the same value
m(g)[8] = 4000g
m[8] = 4000
m = 500 grams
