Rotations And Revolution:- Their Implications

(1)If-Then Implication

Taking the rotation and revolution of the earth into account, does a tree move faster during day or during night?

The kinetic energy of a body rotating at 300 revolutions per minute is 62.8 J. Its angular momentum (in kg m^(2)s^(-2) ) is approximately

The radius of cirlcue, the period of revolution, initial position and sense of revolution are indicated in the figure. y-projection of the radius vector of rotating particle P is :

If p to q is an implication, then the implication ~q to ~p is called its: (A) Converse (B) Contrapositive (C) Inverse (D) Alternative

A fly wheel of moment of inertia I is rotating at n revolutions per sec. The work needed to double the frequency would be -

depict two circulat mothions. The radius of the circle, the period of revolution, the initial position and sense of revolution are indicated in the figures. Obtain the simple harmonic motinosof the x-projection of the radius vector of the rotating particle P in each case.
