Answer:
Derived in explanation
Explanation:
The law of universal gravitation was discovered by Newton in 1686. According to this law:
“Every object in this universe attracts other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.”
Consider two bodies ‘A’ and ‘B’ having masses ‘m1’ and ‘m2’, respectively. They are placed with their centers at distance ‘r’ from each other.
According to this law, force is directly proportional to the product of their masses, that is:
Also, the force is inversely proportional to the square of the distance between them, that is:
On combining both equations we get:
Where ‘G’ is called ‘Gravitational Constant’ and its value is 6.67 x 10⁻¹¹ Nm²/kg².
A capacitor is connected to an ac supply. increasing the frequency of the supply increases the current through the capacitor
A capacitor is a device for storing electrical energy that consists of two insulated conductors in close proximity. The parallel-plate capacitor is a simple example of such a storage device.
A capacitor (also known as a condenser) is a two-terminal passive electrical component that stores energy electrostatically in an electric field. Practical capacitors come in a variety of shapes and sizes, but they all have at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).
Capacitors exist in various shapes and sizes, and their value is measured in farads (F). Capacitors are utilized in both alternating current and direct current systems.

Answer:
1. Walking
2. Pushing the basketball with hand
3. Ball bouncing off the ground
Explanation:
As per Newton's third law of motion every action has an equal and opposite reaction. Looking at the given scenario following are the pairs of action-reaction forces:
1. Walking: When you walk, you apply action and push the ground and the ground pushes you back with the same force.
2. Pushing the basketball with hand: when you push the ball that is action, the ball also applies force on your hand which is the reaction.
3. Ball bouncing off the ground: When ball hits the ground, it applies force i.e. action and the ground pushes it back with the same force which is the reaction.
