Calculate the maximum speed with which a vehicle can travel on a level circular road without skidding.

Calculate the speed with which a vehicle can safely move on a banked circular road. How can wear and tear of tyres be reduced on such a road? (taking into consideration the friction between tyres and road).

A bend in a level road has a radius of 100 m.Find the maximum speed with which a car turning thi bend may have without skidding,if the co-efficient of friction between the tyres and the road is 0.2.

A bend in a level road has radius of 100 m.Find the maximum speed with which a car turning this bend may have without skidding ,if the coefficient of friction between the tyres and road is 0.8.

Write an expression for maximum velocity of a vehicle on an unbanked circular road.

A stone of mass 0.25 kg tied to the end of a string is whirled round in a circle of radius 1.5 m with a speed of 40 rev.//min in a horizontal plane. What is the tension in the string ? What is the maximum speed with which the stone can be whirled around if the string can withstand a maximum tension of 200 N ?

The speed at which current travels in conductor is nearly:

What is the maximum frequency which can be transmitted by ground waves ?

Light of wavelength 600 nm is incident on an aperture of size 2 mm.Calculate the distance upto which the ray of light can travel,such that its spread is less than the size of the aperture.
