Answer:
F = 8 N
Explanation:
Given,
The mass of the smaller block, m = 20 Kg
The mass of the larger block, M = 96 Kg
The coefficient of the static friction, μ = 0.4
The static friction force acting on a body is the minimum horizontal force that is required to keep the smaller block from slipping down the larger block. It is given by the formula,
F = μ · η N
Where, η - normal force acting on the body
F = 0.5 x 20
= 8 N
Hence, the minimum horizontal force that is required to keep the smaller block from slipping down the larger block is, F = 8 N.
Answer:
1. increase
Explanation:
Mass is proportional to gravity. The bigger two objects are, the stronger the force of gravity between them will be.

Answer:
Yes it is true saying that 2nd applience use more power than first one
☄ <u>Universal</u><u> </u><u>Gravitational</u><u> </u><u>Constant</u><u>(</u><u>G</u><u>)</u>
Gravitational constant is a constant of proportionality when F(Gravitational force) is proportional to product of masses and inversely proportional to the distance between them.
- It can be defined as:- Universal gravitational constant is the magnitude of the force between a pair of 1 kg masses that are kept 1 metre apart.
- The SI unit of G is N m²/kg² and the CGS unit of G is Dyne cm² / g².

The value of G (universal gravitational constant) was found out by the scientist Henry Cavendish by using the sensitive torsion balance
