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.

i believe the answer is a hope it and is correct

pretty sure it's false

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
