Physics

When the switch is ON, in a tube light choke is nothing but the coil/ballast (inductor) which is used to induce the high voltage across it.

The direction of heat flow between two objects depends on their temperatures. Heat always flows from a body at higher temperature to a body at a lower temperature.

During uniform motion of an object along a straight line, its velocity remains constant with time.

Proton carry a positive charge.

Basic conditions to execute simple harmonic motion are: (i) There must be an elastic restoring force acting on the system, (ii) the system must have inertia, and (iii) the acceleration of the system should be directly proportional to its displacement and is always directed to mean position.

Ice packed in sawdust does not melt quickly because it provides insulation.

Kirchhoff’s laws are applicable to both D.C. and A.C. circuits.
