How actually current flows through earth wire if leakage happens?

Answer»

The current flows from one point of the circuit, through ground, then back into the circuit. With only one connection to ground there is no circuit for the current to flow through. It can't flow to ground, because there is nowhere for it to flow. Earthing is used to protect you from an electric shock. It does this by providing a PATH for a fault current to flow to earth. It also causes the protective device by using circuit-breaker in high VOLTAGE LEVEL and fuse in low voltage level to switch off the electric current to the circuit that has the fault or unbalance current.

Give one example from your day to day life based on newton's law of motion

Answer»

s first law says that an object remains at rest or motion unless and until it is compelled by a force. EXAMPLE:when we put a luggage over a car when we are travelling, and apply a brake to the motion of the car, the car suddenly STOPS but the luggage has the TENDENCY to REMAIN in motion, so it falls off the car. therefore, luggages are tied over cars with a rope.

What is Cohesion and adhesion​

Answer»

Mark it as brainliest Explanation:Adhesion is the mutual attraction between unlike MOLECULES that causes them to CLING to one another. The WORD can be used in a more general sense to refer to any clinging property (for example, glues and tapes can be called adhesives). The defining feature is that adhesion occurs between two different substances. For example, the adhesion of water molecules to the plastic beaker causes them to cling at a higher level around the edges.Cohesion is the mutual attraction between LIKE molecules that causes them to stick together. The word can ALSO be used in a more general sense to indicate that something, such as a story or a lecture, remains the same throughout. The defining feature of cohesion is that it occurs between two like substances.

What are the examples for archedemics principle​

Answer» MPLE, a ship that is launched sinks into the ocean until the weight of the water it DISPLACES is just equal to its own weight. As the ship is loaded, it sinks deeper, displacing more water, and so the magnitude of the buoyant FORCE continuously MATCHES the weight of the ship and its CARGO.

Difference between circular and curvilinear motion in tabular form

Answer»

CIRCULAR MOTIONCircular motion is the motion of an                  object around a path(circle),from a fixed distance(RADIUS). Example- motion of a goat tethe-red to a POLE. Motion of a giant wheel.etc CURVILINEAR MOTIONCurvilinear motion is the motion of an object along the curves and also on STRAIGHT paths. This kind of motion is not a perfect circle and hence cannot be called curvilinear, but all the parabolic, ellipsic path forms a part of this kind of motion.hope it helps and PLS mark as brainliest:)

Define lenzes law and how it supports law of conservation.Of energy

Answer» LENZ's Law states that, when you induce a current in a WIRE via a changing magnetic field, the current flows through the wire in such a direction so that its magnetic field OPPOSES the change that produced the current. So, what happens when you induce a current by, say, moving a wire through a magnetic field, is that you're converting mechanical energy (the energy of the wire's motion) into electrical energy (the energy carried by the induced current). Lenz's Law ensures that the mechanical energy of the wire is reduced by the same AMOUNT of energy gained by the current. It does this by exerting a force on the wire opposing the wire's motion. This CAUSES the wire to lose mechanical energy (its motion is impeded); it must do work against the induced magnetic field to generate current.
