why is this considered a theory instead of a hypothesis or a law?

a. it is a statement of fact about how nature works instead of an explanation.
b. it provides an explanation for many observations and accepted hypotheses.
c. it describes how to test a possible explanation of one specific relationship.
d. it has not changed over time even though new technology has been developed.

An object dropped from cliff falls with a constant acceleration of 10 metre per second square find its speed of two seconds after it was dropped

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
