A planet moving along an elliptical orbit is closer to the sun at a distance r1 and farthest away at a distance of r2. if v1 and v2 are the linear velocities at these points respectively, then the ratio v1/v2 is

• r2/r1

• (r2/r1)2

• r1 /r2

• (r1/r2)2

A.

r2/r1

From the law of conservation of angular momentum

mr1v1 = mr2v2

r1v1 = r2v2

v1/v2 = r2/r1

From the law of conservation of angular momentum

mr1v1 = mr2v2

r1v1 = r2v2

v1/v2 = r2/r1

Define inertia.

The property by virtue of which the body cannot change its state of rest or uniform motion in a straight line, unless an external force is acting on the body is called as Inertia.

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.

So, the apples fall down.
