Asample of gas with a thermometer immersed in the gas is held over a hot plate. a student is asked to give a step-by-step account of what makes our observation of the temperature of the gas increase. his response include: (a) the molecules speed up. (b) then the molecules collide with one another more often. (c) internal friction makes the collisions inelastic. (d) heat is produced in the collisions. (e) the molecules of the gas transfer more energy to the thermometer when they strike it, so we observe that the temperature has gone up. (f) the same process can take place without the use of a hot plate if you quickly push in the piston in an insulated cylinder containing the gas

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
