Consider the orbit of a typical comet around the sun, which is marked at five different positions, s, z, u, x , and p. sun a b x z p s u using kepler's second law of planetary motion, rank those positions in order of their relative speeds, with the position for the fastest speed first.

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?
