By examining the effective potential energy find the radius at which a planet (or cornet) with angular momentum t can orbit the sun in a circular orbit with fixed radius. [look at du_eff/dr.] (b) show that this circular orbit is stable, in the sense that a small radial nudge will cause only small radial oscillations. [look at d^2u_eff/dr^2.] show that the period of these oscillations is equal to the planet's orbital period. u_eff(r) = - g m_1 m_2/r + l^2/2 mu r^2.

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

brainliest

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

its a circle not a square that's simple silly.
