Question

If X-Y-Z and l(XZ)= 3√7, l(XY)=√7,then l(YZ)=?

Answer 1

Answer:

Equal areas in equal times" means the rate at which area is swept out on the orbit (dA/dt) is constant. So Kepler's Second Law Revised: The rate at which a planet sweeps out area on its orbit is equal to one-half its angular momentum divided by its mass (the specific angular momentum). Angular momentum is conserved.
