Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
If they become closer, it is increased, and if the objects become farther away is decreased.
The North Pole would be your answer
The weight is 45 N, because the three chains hold the sign, and each contributes 15 N.
Notice that the mass would be the weight/acceleration of gravity, m = 45/9.8 kg. But they ask the weight (force, so Newtons)
Answer:
Nuclease is the answer I know
I hope this is the answer
