Question 17 options: a 71.8 kg man goes from an area where the acceleration due to gravity is 9.79 m/s2 to an area where the acceleration due to gravity is 9.82 m/s2.what is the change (in kilograms), to the mass of the man? respond to three significant digits expressed as a. bc and remember to record your responses for a, b, and c in that order.
(i was thinking the answer would be 0 but im not sure)

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
