A temperature controller, designed to work in a steam environment, involves a bimetallic strip constructed of brass and steel, connected at their ends by rivets (Figure 1). Each of the metals is 3.0 mm thick. At 10 ∘C, the strip is 10.0 cm long and straight. Find the radius of curvature r of the assembly at 100 ∘C.

Question 9: use your experiences from questions 6, 7, and 8 to you state a general rule for identifying the three declination ranges given the observer's latitude.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
