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.
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.

Mandeep climbs up a 10 meter ladder with a force of 4 Newtons in 20 seconds. What is his power output?
40 Nm/sec
2 Nm
2 Nm/sec
40 Nm
Explanation:
Work Done = Force * Displacement
= (4N)(10m) = 40J.
Power = Work Done / Time
= (40J)/(20s) = 2J/s = 2 Nm/sec.
Answer:
40 m

When a bus is moving (especially with a high speed) on the road suddenly stops or suddenly changes its direction, the luggage on the top due to inertia of motion and direction continues to remain in the motion or in the same direction of motion. As a result, the luggage may get thrown out from the bus roof ---is an example of which law of motion?
Answer:
First law of motion
Explanation:
I say this because this example shows how an object is staying persistent unless it's compled to change

What is the net force acting on the object above?
Answer:
5N to the right
Explanation:
You have a force of 2N acting on the object to the right, 1N to the left, and another 4N to the right. if we add all of these forces together, taking to the right as positive, and to the left as negative, we get 2 + 4 - 1, which is 6 - 1, which is equal to 5, and since it's positive, it's a net force to the right.
1. A sled is being pulled to the left by 5 dogs, each dog pulling with 6 Newtons of force. Find the net force (ignore friction).
2. If a person pulls on a cart to the right with a force of 10N and a second person pulls to the left with a force of 3N, what is the net force on the cart ignoring all other forces?
3. A 2N and 6N force pulls on an object to the right and a 4N force pulls to the left a 0.5kg object. What is the net force on the object if you ignore all other forces?
4. A 20kg bike accelerates at 10m/s^2. With what force was the person pedaling if friction exerted a force of 100N

Will the net force be greater or lesser for objects with greater mass?
Answer:
The answer is
→ If an object has a greater mass, then the net force will be lesser.
Explanation:
The net force will be lesser because the greater mass the object is, the slower the net force will be.
If we were to talk about lesser mass in an object, then the net force will be faster, but this isn't the case right now.

Explain constant and changing velocity.
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.

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?
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
