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.

What is the net force acting on the object above?
Answers
There’s a force of 6 N pulling to the right (the positive direction) and 1 N pulling left (the negative direction).
Net force= 6 N - 1 N = 5 N to the right
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.
Mandeep climbs up a 10 meter ladder with a force of 4 Newtons in 20 seconds. What is his power output?

Explanation:
Work Done = Force * Displacement
= (4N)(10m) = 40J.
Power = Work Done / Time

Will the net force be greater or lesser for objects with greater mass?
Answers
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.

Charlotte completed an experiment in which she investigated and discovered that an electrically charged object can attract an uncharged object without any contact. She used a PVC pipe and small pieces of paper for her experiment. Each time, she rubbed the PVC pipe with a cloth to give it a charge and then held it over paper. What would be Charlotte's control group in this experiment?
A. Using the cloth and rubbing it against the PVC pipe
B. Taking the pieces of paper and rubbing it against the cloth
C. Not rubbing the cloth against the PVC pipe or the paper
D. Rubbing the cloth against both the paper and the PVC pipe

Answer:
Your Best Answer would be C
Hope this helps :)
Charlotte's control group in this experiment would be: not rubbing the cloth against the PVC pipe or the paper. Option (c) is correct.
What is control group in the experiment?In a scientific experiment, a control group is a subset of participants who are not included in the main experiment and whose outcomes are unaffected by the independent variable under study. By isolating the effects of the independent variable on the experiment, this can help rule out other possible explanations for the findings of the experiment.
Positive and negative control groups are the other two categories into which they might be divided.
Not all scientific studies call for the use of control groups. The use of controls is crucial when an experimental conditions are complex and difficult to isolate.

reflect off these materials. When light reflects, it is bouncing off something. Windows transmit most of the light that strikes them, but they also reflect light. If you have a lamp turned on near a window at night, you can see the reflection of the lamp in the window.
Transparent and translucent materials also absorb some of the light that strikes them. When something absorbs light, it is soaking up the light. When light is absorbed by an object, the light energy changes to heat energy and the object heats up. If you touch a window that has been in the sunlight, you will notice that it is warm.
Opaque materials do not transmit any light. All of the light that strikes an opaque material is reflected or absorbe

Answers
Answer:
6.93 km/h
Explanation:
To calculate her average speed, we need the "speed" formula, which is:

You plug in your numbers and it will give you the answer.
Speed = 4.5km/0.65hr
