Answer:
Electrical Resistance is a measure of the opposition to current flow in an electrical circuit
Types: variable resistance and set resistance
Explanation:
The force of attraction between two objects can be illustrated using Newton's Law of Universal Gravitation.
The relation between the different parameters is shown in the attached image.
Now, from the relation, we can deduce that the force between the two objects is directly proportional to the masses of the two objects.
This means that, if the mass of one object is doubled, then the force between the two objects will also be doubled.
As we know,

so, let's solve for charge (q) :
time = 5 minutes = 5 × 60 seconds = 300 seconds.
hence, the charge = 60 coulombs (C)
Answer:
Due to total internal reflection lose of imformation is almost none in optic fibre. Less time is required to transmit the imformation.
Explanation:
They would just have to box in a higher weight class
