The planet quirk is flat. gps satellites hover over quirk at an altitude of 20, 000 km (unlike earth where the satellites circle twice a day). see how accurately you can estimate the distance l from the point directly below the satellite to a point on the planet surface knowing the distance h from the satellite to the point on the surface in two cases. (the letter h is for hypotenuse.) a) use a calculator to compute δl/δh for h = h0±δh = 25, 000±δh, and δh = 1, 10−1, 10−2. write an estimate for l in the form |l − l0| = |δl| ≤ c|δh| choosing the simplest round number c that works for all three cases

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
