Answer:
The distance traveled!
Explanation:
This is a velocity time graph of an object moving in a straight line due North.
This might help and it might not:
Gravitation is the acting force between two bodies. On the other hand, gravity is the force occurring between an object and the very big object earth. Every object with some mass exerts the gravitational force on every other object having some mass. This force and its strength depend on the masses of the objects under consideration. Gravity helps to keep the planets to move in their orbit around the sun.
Gravitation is the force of attraction between any two bodies in the universe. In our universe, each object attracts each other with a certain amount of force. The large distance of separation is the main reason for its weak nature.
Gravity is the weakest type of fundamental force in nature. Still, it holds together the entire solar systems and galaxies.
Gravity has the existence with unlimited range.
Answer:
New force, ![F'=48\times 10^3\ N](https://tex.z-dn.net/?f=F%27%3D48%5Ctimes%2010%5E3%5C%20N)
Explanation:
It is given that,
Force acting between two charged particles, ![F=7.5\times 10^2\ N](https://tex.z-dn.net/?f=F%3D7.5%5Ctimes%2010%5E2%5C%20N)
We need to find the force if they are moved so they are only one-eighth as far apart.
The force between two charged particles separated at a distance of r is given by :
............(1)
If the charges are one-eighth as far apart then, r' =(1/8)r and new force is given by :
..........(2)
Dividing equation (1) and (2) :
![\dfrac{F}{F'}=\dfrac{1}{64}](https://tex.z-dn.net/?f=%5Cdfrac%7BF%7D%7BF%27%7D%3D%5Cdfrac%7B1%7D%7B64%7D)
![F'=7.5\times 10^2\ N\times 64](https://tex.z-dn.net/?f=F%27%3D7.5%5Ctimes%2010%5E2%5C%20N%5Ctimes%2064)
F' = 48000 N
or
![F'=48\times 10^3\ N](https://tex.z-dn.net/?f=F%27%3D48%5Ctimes%2010%5E3%5C%20N)
Hence, this is the required solution.
The correct option is C.
From the information given above, one can easily conclude that electromagnetic Y is the strongest because, it produces the higher amount of current compare to the other electromagnets. Electromagnet W is the weakest because it produces the lowest amount of current.
