(a)Consider one object which has a temperature of 70°C in another object which has a temperature of 10°C. The two objects are placed next to each other in the particles in each object begin colliding. Will any of the collisions result in the transfer of energy from object to the object one? Explain. (b)Suppose that object one in object to have reached a thermal equilibrium. Do the particles of the two objects steel collide with each other? If so do any of the collisions result in the transfer of energy between the two objects? Explain.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
