Asmooth circular hoop with a radius of 0.800 m is placed flat on the floor. a 0.300-kg particle slides around the inside edge of the hoop. the particle is given an initial speed of 10.00 m/s. after one revolution, its speed has dropped to 5.00 m/s because of friction with the floor.
(a) find the energy transformed from mechanical to internal in the particle—hoop—floor system as a result of friction in one revolution.
(b) what is the total number of revolutions the particle makes before stopping? assume the friction force remains constant during the entire motion.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
