Along steel i-beam used in bridge construction has a length of 15.0 m. the beam may be exposed to temperatures as low as −23°c in the winter and as high as 32°c in the summer. what is the difference in length of the beam between these two temperature extremes? (give the absolute value of the difference. enter your answer in mm.)

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
