Two students with masses of 40kg and 32 kg are sitting 22 m apart. What is the gravitational force of attraction between them?
HACTEHA [7]

I get 1.76 x 10^-10 Newton.

That's 0.000 000 000 176 Newton

Which is about 0.000 000 000 635 ounce of force pulling them together.

That's why we never notice it.

valkas [14]

Answer:

In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.

Explanation:

There are two ways to connect electrical circuits, in series and in parallel.

Series circuits have the problem that when one element is damaged, the entire circuit is interrupted and runs out of power.

In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.

In Breaker it is connected in series so that when some maintenance is needed, all the energy can be interrupted simultaneously and if some equipment tries to consume a lot of energy, the circuit prevents this action by interrupting the energy of the entire circuit
