The steps taken in scientific studies often follow similar patterns. which answer correctly describes the order in which the steps should be performed?
a. state a hypothesis, then design an experiment to test it.
b. perform an experiment, then state a hypothesis that fits the results.
c. draw a conclusion, then design an experiment to support it.
d. state a theory, then find examples to support it so that it becomes a law.

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 = ?
