A change in the position of a body with respect to time relative to a reference point is motion.
Because there is no absolute point of reference, there is no true discernible absolute motion, and therefore, everything is said to be moving constantly.
Hope that helped =)
Answer:
Explanation:
We are given that
We have to find the rate at which R is changing.
In parallel
Using the formula
Substitute the values
An arrow in flight cannot accelerate, since there's no force on it.
I would say B , not sure if its correct
solution:
When an uncharged conducting object brought near to a charged insulating object there is a force on the conducting object to move the electrons within it to opposite sides of the conductor. That means there is a separation of charges in the conducting object in the presence of the charged insulating object near to it but the charge on the conducting object is neutral.
Thus, the conducting object is uncharged.
There is a force of attraction between the uncharged conducting object and the insulating object when it brought near to the insulating object.
Thus, there is a force on the conducting object.
The conductor remains uncharged and a force is exerted on it.
