WebVerified answer. physics. Use conservation of energy and earlier Eq. for the total energy to show that the speed v v of an object in an elliptical orbit sat- isfies the relation. v^2=G M\left (\frac {2} {r}-\frac {1} {a}\right) . v2 = GM (r2 − a1). Here r r is the distance of the orbiting body from the central body of mass M M. WebIn this chapter, we are going to take a closer look at the families of compounds that have carbon linked through a single covalent bond to an O, N, or S.
