The vector position of a 3.70 g particle moving in the xy plane varies in time according to r1 = (3î + 3ĵ)t + 2ĵt^2 where t is in seconds and r with arrow is in centimeters. at the same time, the vector position of a 5.65 g particle varies as r2 = 3î − 2ît2 − 6ĵt.
(a) determine the vector position of the center of mass at t = 2.60.
(b) determine the linear momentum of the system at t = 2.60.
(c) determine the velocity of the center of mass at t = 2.60.
(d) determine the acceleration of the center of mass at t = 2.60.
(e) determine the net force exerted on the two-particle system at t = 2.60.

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
