Suppose the ends of a 27-m-long steel beam are rigidly clamped at 0°c to prevent expansion. the rail has a cross-sectional area of 35 cm^2. what force does the beam exert when it is heated to 39°c? (αsteel = 1.1 × 10^−5/c°, ysteel = 2.0 × 10^11 n/m^2).

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Which is not an example of how an object gains elastic potential energy by stretching? a. jumping on a pogo stick b. pulling on a rubber band c. jumping on a trampoline

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!
