what is principle of superposition?

Posted by Divya Tripathy 7 years, 3 months ago

1 answers

Ayushi Ayushi 7 years, 3 months ago

The principle of superposition may be applied to waves whenever two (or more) waves travelling through the same medium at the same time. The waves pass through each other without being disturbed. The net displacement of the medium at any point in space or time, is simply the sum of the individual wave displacements.

Carnot Engine is a reversible engine.
Carnot's theorem consists of two parts

(i) no engine working between two given temperatures can be more efficent than a reversible Carnot engine working between same source and sink.
(ii) all reversible engines working between same source and sink (same limits or temperature) have the same efficiency irrespective the working substance.

State and explain theorem of parallel axis?

Posted by Aakarshit Guleria 7 years, 3 months ago

CBSE > Class 11 > Physics

2 answers

Nancy Rajput 7 years, 3 months ago

The moment of inertia of a body about any axis is equal to the sum of the moments of inertia of the body about a parallel axis passing through its centre of mass and the product of its mass and the square of distance between the two parallel axes. formulae is I=Ig+Md^2

1Thank You

???. Pragati 7 years, 3 months ago

The Parallel Axis Theorem states that a bodies moment of inertia about any given axis is the moment of inertia about the centroid plus the mass of the body times the distance between the point and the centroid squared.

In limiting friction body does not gain displacementso work done zero

0Thank You

Yogita Ingle 7 years, 3 months ago

Static friction is a non-conservative force, and therefore has no associated potential energy. When static friction is internal, however, it is a non-dissipative force, performing zero net work on the chosen system. The reason is that static friction guarantees that the two interacting objects will undergo the same displacement. Thus, the work done on the two objects will cancel by Newton's Third Law.

Relation between linear velocity and angular velocity.

Posted by Rohitman Jorwal 7 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 3 months ago

Linear velocity is defined as the rate of change of displacement. The unit of linear velocity is m/s.
Angular velocity of a body is the rate of change of angular displacement over a period of time. The unit of angular velocity is rad/s.

Magnitude is the product of numerical value and unit

2Thank You

Yogita Ingle 7 years, 3 months ago

Magnitude represents the size of the physical quantity.

Magnitude is like how much that physicalo quantitiy is.

Example
If we say 4 second

Here 4 represents the magnitude of the time.

???. Pragati 7 years, 3 months ago

The difference between the specific heat of a gas at constant pressure( cp ) and its specific heat at constant( cv ) volume is equal to the universal gas constant(R) divided by the molecular weight(M) of the gas. i.e. cp−cv=RM .This relation is known. as Mayer's formula.
