Explanation

Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors.

Pure elemental silver is one of the best electrical conductors.

Explanation

A body rolling freely on the surface of earth eventually comes to rest because It suffers fraction 

Explanation

Explanation

Mechanics is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects.

Forces applied to objects result in displacements or changes of an object's position relative to its environment.

Explanation

The value of g at a particular point outside the earth is 10 m/s2.

Explanation

A ball falls vertically and bounces on the ground . The following statements are about the focus acting while the balls is in contact with the ground. The force that the ball exerts on the ground is always equal in magnitude and opposite in the direction to the force the ground exerts on the ball

Explanation

Newton's third law concerns the forces of interaction between two bodies.

Which of following statements relating to third law is not correct The two forces are equal and opposite so the bodies are in equilibrium 

Explanation

The process by which free electrons are emitted from the metal surface by the application of light is called photoelectric emission.

Explanation

An object whose mass is 100 grams starts from rest and moves with consent acceleration of 20 centimeters per second square. At the end of 8 seconds its momentum is in g cm/s 16000
