If two same forces acting on a body in opposite direction, they will cancel each other. In box 2, 2 N is acting from both top and bottom and it will cancel. Similarly, 5 N is acting from both left and right and result in cancellation in magnitude. Therefore, box 2 cannot be displaced and it is equilibrium.
What is force?Force is an external agent acting on a body to change it from the state of motion or rest. Force is dependent on the mass of the body. Force is a vector quantity and thus, having a magnitude and direction.
If two same forces acting on a body from same directions, then the resultant force will be the sum of the two forces. If these forces are acting in opposite directions, then they will cancel each other in magnitude.
Here, in box 2 equal forces are acting from opposite directions. 2 N from top and bottom will cancel each other and similar for 5 N from left and right. Hence, the net force acting upon the box-2 is zero. Thus, box 2 is said to be in equilibrium.

A girl rides her scooter to school, a total distance of 4.5km. She has to slow down twice to cross busy streets, but overall the journey takes her 0.65h. What is her average speed during the trip?
Answers
Answer:
6.93 km/h
Explanation:
To calculate her average speed, we need the "speed" formula, which is:
average speed = distance / time
You plug in your numbers and it will give you the answer.
Speed = 4.5km/0.65hr
= 6.923 km/h
based on Newton's first law of motion describe what happens if you try and push a student. What happens if the student pushes back?
Answers
Answer:
If you push someone, then you are exerting force which will push them into motion. Same goes for when they push you.
Before Galileo and Newton, many people thought objects slowed down because they had a natural built in tendency to do so. But those people weren't taking into account the many forces—e.g., friction, gravity, and air resistance—here on Earth that cause objects to change their velocity. If we could observe the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object's motion free from any external influences. In deep interstellar space, we would observe that if an object had a velocity, it would continue moving with that velocity until there was some force to cause a change in the motion. Similarly, if an object were at rest in interstellar space, it would remain at rest until there was a force to cause it to change its motion.
In the video below, we can see that objects in the international space station either remain at rest or continue with constant velocity relative to the space station until acted upon by a force.

Using simple language, explain how your demonstration shows the effect of distance on electric forces. Use the terms electric charge, electric field, and electric force.
Answers
Explanation:
For a charge concentrated nearly at a point, the electric field is directly proportional to the amount of charge; it is inversely proportional to the square of the distance radially away from the centre of the source charge and depends also upon the nature of the medium.
The electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.
Coulomb's law describes the electric force between charged objects. It should be noted that gravitational force and electric forces reduce with the square of the distance between the objects.
Every constituent of matter possesses an electric charge that can either be positive, negative or zero. In electrostatics, the electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.
When the separation distance is increased, it'll lead to a reduction in the force of attraction between the objects.

Explain constant and changing velocity.
Answers
Answer:
To summarize, an object moving in a uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
Answer:
In order for the velocity to be constant, the magnitude of the velocity (or speed) and the direction of the velocity must not change. Therefore, an object that travels with constant velocity covers the same distance during each time interval and moves in the same direction during the same time interval.
