Answer:
2N
Explanation:
Given that a student pulls down with a force of 40 N on a rope that winds around a pulley of radius 5 cm. find the torque?
Solution
Using the formula
Torque = Force × radius
I.e
Torque = F r
Where
F = 40N
r = 5 cm = 5/100 = 0.05m
Substitute all the parameters into the formula
Torque = 40 × 0.05
Torque = 2 N
Therefore, the torque on this scenario is 2 N

Answer:
Inverse
Explanation:
The force of gravity between two objects follows an <u>inverse</u> square law with regard to the distance between them.
<em>The inverse square law refers to any law that stipulates that a particular quantity varies inversely to the square of the distance to its source and according to the law of universal gravitation, the gravitational force of attraction between two objects is </em><em>inversely proportional to the square of the distance separating the two objects. </em>
Hence, the law of universal gravitation obeys the inverse square law.
Answer:
there is an infinite number of images because it is reflected off of the mirrors. the images in the mirror will "move" if either mirror is shifted because the angle of reflection. the images are the same because its just a repeated reflection. i see the object on both sides, repeated as far as i can see in both mirrors.
Explanation:
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that both charge particles will exert equal and opposite force on each other
so here the force on both the charges will be equal in magnitude
so we will have
here we have
now we have
Part b)
Now for the force between two charges we can say
now we have
now we have
