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.

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.

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

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

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

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.
