I think it is c I'm only in 7th grade but I'm pretty sure that the answer is c
Answer:
115kg
Explanation:
Given parameters:
Weight of the refrigerator = 1127N
Unknown:
Mass of the refrigerator = ?
Solution:
Weight is the force that acts on an object due to gravity;
Weight = mass x acceleration due to gravity
Acceleration due to gravity = 9.8m/s²
Now, input the parameters and solve for mass;
1127 = mass x 9.8
mass = = 115kg
If two charges are moved so that the distance between them is reduced
by half, then the forces between them become 4 times as strong.
