When hiking, the human body can produce on the order of 500 W of body heat. For a hiker that is wearing insulating cotton clothing 5-mm thick, what wind speed is necessary for the hiker to feel perfectly comfortable (i. e. the heat-out matches the heat-generated) when standing still with an ambient temperature of 40oF

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
