If the radius of the Earth's orbit around the Sun is 150 million km, what is the speed of the Earth?

Answer 1

The gravitation force grant the centripetal force.

#F_g = F_c# #F_g=(G M_(sun) M_(earth))/(R^2)# Newton gravitation law where #G=6.67*10^(-11) m^3/(kg*s)#, #R=1.5 *10^11 m, M_(sun)=2*10^30# #(G M_(sun) M_(earth))/(R^2)=M_(earth)v^2/R# #v^2=G M_(sun)/R# #v=29.8 (km)/s# #v_(mean)=29,783 (km)/s# sorce: https://tutor.hix.ai

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
