A thick wire is suspended from a rigid support, but no load is attached to its free end. Is this wire under stress?

The phase diffrence between both side of a nodes.

Why does a hot liquid move faster than cold liquid?

Why should a thermometer bulb have a small heat capacity?

What are ideal gases?

Does the radius of gyration depend upon the speed of rotation of the body?

The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative: Work done by an applied force on a body moving on a rough horizontal plane with uniform velocity.

A LASER is a source of very intense, monochromatic, and unidirectional beam of light. These properties of a laser light can be exploited to measure long distances. The distance of the Moon from the Earth has been already determined very precisely using a laser as a source of light. A laser light beamed at the Moon takes 2.56s to return after reflection at the Moon’s surface. How much is the radius of the lunar orbit around the Earth?

At which points of trajectory speed will be minimum and maximum?

What is the value of pressure coefficient of gases?
