Answer:
Explanation:
As we know that disc can be treated as sheet of uniform charge density if the electric field is to be calculated at a point near its surface
so we can say that here electric field between two opposite charged disc is given as
so we have
here we know that
now we have
Answer:
People can capture geothermal energy through:Geothermal power plants, which use heat from deep inside the Earth to generate steam to make electricity. Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings.

Answer:
Newton's second law of motion is also known as law of acceleration.
Force, mass and acceleration are the three factors needed two explain the law.
Explanation:
This law states that if there is an unbalanced force acted upon an object (either in rest or in motion ) the force causes an acceleration. The acceleration is directly proportional to the force.
F(net)α a, the proportionality constant is the mass of the object.
Another definition for the law is
F(net)= m.a where m stands for mass and a is acceleration.
The first collision because a greater amount of momentum must be taken and used in order to push the cart back, giving it a greater mass and impulse
