Arslaanji I think it is banking of road if it is the question : the answer is:the ends of curved roads are raised because the raider while travelling on curved road feels to lean inward to avoid that feeling banking of road is done

it depends on nature of substance .. the m.p. of those substances which expand on melting (eg. paraffin wax ,water) increase with inc. in pressure and m.p. of those substance which contract on melting (eg. iron ) decrease with inc. in pressure

How will you distinguish between a hard boiled egg and a raw egg by spinning each on table top?

Posted by Siddhartha Singh 4 years, 6 months ago

Sia ? 4 years, 6 months ago

To distinguish between a hard boiled egg and a raw egg we spin each on a table top. The egg which spins at a slower rate shall be raw. This is because in a raw egg liquid matter inside tries to get away from its axis of rotation. Therefore its moment of inertia increases. As t = I α = constant therefore α decreases i.e. raw egg will spin with smaller angular acceleration. The reverse is true for a hard boiled egg which will rotate more or less like a rigid body.

Navpreet Kaur 7 years, 11 months ago

Banking of roads means to construct a road in such a way so that its outter side lift in little bit upward direction. This is done to prevent accidents because on a levelled road if the speed increase from [urg]1/2 then the friction is unsufficent to provide centripital force and the car will skid off Thanks?

4Thank You

Arnav Singh 7 years, 11 months ago

On a levelled road basically depends upon the coefficient of static friction but friction is not reliable as it changed as the change in the condition of tyre and road and other climatic condition so to add safety a curve is constricted with its outer edges are little raised above the inner edge and is called banking of curve

Difference between stationary wave and progessive wave

Posted by Miss Taya 7 years, 11 months ago

CBSE > Class 11 > Physics

1 answers

Jai Attri 7 years, 11 months ago

A wave that travels from one point of the medium to another is called a progressive wave. A progressive wave may be transverse or longitudinal. A stationary wave is formed when two identical waves travelling on the opposite directions along a straight line interfere. The superposition of two waves will give rise to a stationary wave. Formation of stationary wave is possible only in bounded medium.
