Kepler's third law i.e. T^2propR^3 , is a consequence of law of conservation of

Consider the following statements. Kepler’s second law is based on the law of conservation of angular momentum. Kepler’s third law is based on Newton’s law of gravitation.

STATEMENT -1 : Kepler's second law is the consequence of law of conservation of angular momentum. STATEMENT -2 : In planetary motion, the momentum, angular momentum and mechanical energy is conserved. STATEMENT -3 : The gravitational field of a circular ring is maximum at a point upon axis at distance (R )/(sqrt(2)) from the centre, where R is the radius of ring.

Statement -1 : Torque is equal to rate of change of angular momentum . Statement -2: Angular momentum depends on moment of inertia and angular velocity.

Assertion: Kepler's second law can be understood by conservation of angular momentum principle. Reason: Kepler's second law is related with areal velocity which can further be proved to be used on coservation of angular momentum as (dA//dt)=(r^(2)omega)//2 .

Statement 1: Electric current (flow of electrons) creates heat in a resistor. Statement 2 : Heat in the resistor is created according to the law of energy conservation. Explain Statement 1 with the help of Statement 2.
