Predict the changes in atomic motion within a sample as the material sublimes. a) the atomic motion within the sample increases as the material sublimes. eliminate b) atomic motion within the sample will decrease as the material sublimes. c) changing phases through sublimation has no effect on the atomic motion. d) sublimation divides the atomic motion of the sample by the phase change.

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

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.

What is an electric motor? explain its operation. 2-3 sentence
