Binding Energy of a satellite: The minimum amount of energy required for a satellite to escape from earth's gravitational influence is called as Binding Energy of a satellite.
Binding Energy = GMm/2r
Where, G is Gravitational Constant
M is mass of earth
m is mass of satellite
r is radius of orbit i.e. Radius of earth + height at which staellite is orbiting the earth.
Escape Energy: The minimum amount of energy with which a body should be projected from the surface of the earth, so that it escapes from the earth's gravitational field, is called the Escape Energy of the body.
The velocity with which the body travels is known as Escape Velocity. It is given by
V = √2gR)
Where, g is acceleration due to gravity
R is radius of Earth.

Balraj Singh 7 years, 2 months ago

Terminal velocity is the maximum constant velocity which aquire the body falling through a viscous mediam

Yogita Ingle 7 years, 2 months ago

Terminal velocity is the maximum velocity of a body moving through a viscous fluid.
It is attained when force of resistance of the medium is equal and opposite to the force of gravity.
As the velocity is increasing the retarding force will also increase and a stage will come when the force of gravity becomes equal to resistance force.
After that point velocity won’t increase and this velocity is known as terminal velocity.

What is meant by thermal conductivity? What are the SI unit and CGS unit of cofficient of thermal conductivity???

Posted by Diksha Kohar 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 2 months ago

Thermal conductivity is defined as the property of any material to conduct heat. Heat transfer takes place at a lower rate in all the materials of low thermal conductivity. Materials having thermal conductivity are greatly used in heat sink applications and materials having low thermal conductivity are used as thermal insulation. A thermal conductivity of a material depends on the temperature, and its reciprocal is known as thermal resistivity.
The SI unit of thermal conductivity is watts per meter-Kelvin and its variables are Mass, Length, Time, and temperature. In the Imperial unit, thermal conductivity is measured in BTU.

Define law of conservation of energey for 11th standard??

Posted by Siva Nagappan 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 2 months ago

he law of conservation of energy states that energy can neither be created nor be destroyed. It may be transferred from one of its forms to the other. If you take all forms of energy into account, the total energy of an isolated system always remains constant.
So in an isolated system such as the universe, if there is a loss of energy in some part of it, there must be a gain of an equal amount of energy in some other part of the universe. Although this principle cannot be proved, there is no known example of a violation of the law of conservation of energy.

Mass	Weight
Mass can never be zero.	Weight can be zero. As in space if no gravity acts upon an object, its weight becomes zero.
Mass is a scalar quantity. It has magnitude.	Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.
Mass is commonly measured in kilograms and grams.	Weight is commonly measured in Newtons.
Mass doesn’t change according to location.	Weight varies according to location.
The mass may be measured using an ordinary balance.	Weight is measured using a spring balance.

Weight is a quantity in which gravity included while in mass there is no includation of gravity where weight is equal to mass multiply with acceleration due to gravity

Turbulent flow:- When the velocity of liquid becomes greater than the critical velocity, the particles follow zig-zag path, such a disordered is called turbulent flow. Laminar flow:- The flow in which liquid moves in the form of layers. Streamline flow:- It is an orderly flow of fluid in which all the molecules of the fluid passing through a certain point have same velocity.
