Athin stream of water flows smoothly from a faucet and falls straight down. at one point the water is flowing at a speed of v1 = 1.71 m/s. at a lower point, the diameter of the stream has decreased by a factor of 0.805. what is the vertical distance h between these two points?

Which describe reflection? check all that apply. light bounces off a boundary.

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

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.
