What is a difference between fission and nuclear decay?
A. Fission involves a change in the nucleus of an atom, while nuclear decay does not.
B. Fission releases particles, while nuclear decay absorbs particles.
C. Fission results in products of relatively similar masses, while nuclear decay results in products of very different masses.
D. Fission is a slow, natural process that occurs spontaneously, while nuclear decay is a fast and generally human-induced process.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 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. 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.
