Physics Questions

Kelvin temperature scale is the temperature scale that is based upon absolute zero.

Synchronous motor is a motor which runs at a constant speed irrespective of load attached to it. So the speed regulation of synchronous motor is ZERO.

The strength of an electromagnet can be increased by increasing the cross-sectional area, increasing the number of turns, increasing current supply, increasing the length of the coiled wire.

Electrical discharge machining (EDM), also known as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges.

We know that most of the metals are goof conductors of electricity and heat. Metals are very strong but they are malleable i.e, they can be bent into a shape. These are shiny when they are cut or polished. 

Hence, metals are malleable, conductors and luster. All the above are properties of the metals.

These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers. Types of intrusive igneous rocks are granite and basalt .

A batholith is the largest of the intrusive bodies.
