1) A. 2

The electrostatic force between two objects is given by:

where

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is the separation between the two objects

In this problem, the charge of one object is doubled, so

Therefore the new force is

So, the force will double.

2) D. 1/4

Using the same formula, the electrostatic force between the two objects is:

In this problem, the distance between the two objects is doubled, so

Therefore the new force is

So, the force will decrease to 1/4 of its original value.

3) 4/9

Using the same formula, the electrostatic force between the two objects is:

In this problem, the amount of charge on both objects doubles, so

Also, the distance is tripled

Therefore the new force is

So, the force will decrease to 4/9 of its original value.

i wanna say it’s between b and d, leaning more towards b.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
