Give reason for the statement that "The rotating wheels of any vehicle throw out mud, if any tangentially".

Give reason of camphor disappears without leaving any residue

A wheel of radius R has an axle of radius R//5 . A force F is applied tangentially to the wheel. To keep the system in a state of "rotational" rest, a force F' is applied tangentially to the axle. The value of F' is

A string of mass M as a circular loop rotates abot its axis on a frictionless horizontal plane at a uniform rate so that the tangential plane at a uniform rate so that the tangential speed of any particle of the string is v . If a small transverse disturbance is produced at a point of the loop, then speed (relative to the string) of disturbance on the string is

A wheel of mass 10 kg and radius 0.2 m is rotating at an angular speed of 100 rpm, when the motion is turned off. Neglecting the friction at the axis. Calculate the force that must be applied tangentially to the wheel to bring it to rest in 10 rev. Assumed wheel to be a disc.

A wheel of radius 0.5 m rotates with a constant angular speed about an axis perpendicular to its center. A point on the wheel that is 0.2 m from the center has a tangential speed of 2 m/s. Determine the tangential speed of a point 0.4 m from the center of the wheel.

Give any four reasons against the social responsibilities of a businessman .

The circumference of the back-sided wheel of a vehicle is 1 m greater than that of front side wheel. To travel 600 m, the front wheel rotates 30 times more than the back wheel. The circumference of the front wheel is (a) 2m (b) 4m (c) 5m (d) None of these
