R-410a enters the evaporator (the cold heat exchanger) in an air-conditioner unit at 20$^{\circ} \mathrm{C}$, x = 28% and leaves at 20$^{\circ} \mathrm{C}$, x = 1. - tdown < tup Namxcingorem ipsum dolor sit amet, consectetur adipiscing elit. The dashed lines are drawn at the same angle as the surface of the ramp. Correct answer to the question A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. The diagram below represents a flower, the reproductive structure of some plants. If the inclination of the plane is 30 and the coefficient of sliding friction is k = 0.1 , find the total time for the block to return to the point of projection. StartFra Look at michelangelo's creation of adam. it alludes to the time allotted to keep up a home and family.
