Virtual Lab Introduction: A student in a science lab is investigating heat transfer and thermal energy conservation as she mixes hot and cold water. She first measures out her
desired amount of cold water into a Styrofoam cup. She then measures out hot water from the faucet or from a pot hot water on her stove. After she
measures the temperature of the hot and cold waters, she pours the hot water into the cold water. She monitors the temperature of the mixed waters and
records the final temperature. She uses a standard thermometer to record the temperatures. She does three trials, which are shown below:

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.
