Gravity is force between objects that are moving closer to one another.
a. a constant
b. a repulsive
c. an attractive

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?

Photons with the highest energy have the longest period

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.
