Calculate the acceleration due to gravity on the surface of a satellite having a mass of 7.4×1022kg and a radius of 1.74×106m G=6.7×10-11Nm/kg2. Which satellite do you think it could it could be?
let R1 be an equivalence relation on set A.for x,y is an element of set A ,defined by xR2y biimplies xR1y and yR1x ,then show that R2 isan equivalence relation on set A
