Why is this considered a theory instead of a hypothesis

or a law?

Different microscopic organisms cause different

diseases. When a dangerous microscopic organism is

transferred from one person to many people, the

disease it carries will spread

O It is a statement of fact about how nature works

instead of an explanation

O It provides an explanation for many observations

and accepted hypotheses.

O It describes how to test a possible explanation of

one specific relationship,

O It has not changed over time even though new

technology has been developed.

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 = ?
