Some cookware has a stainless steel interior (α=17.3×10−6k−1) and a copper bottom (α=17.0×10−6k−1) for better heat distribution. suppose an 8.0-in. pot of this construction is heated to 620 ∘c on the stove. part a if the initial temperature of the pot is 22 ∘c, what is the difference in diameter change for the copper and the steel?

Will you chech and finish these for me, because i am stumped with them.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

How can you increase the strength of an electromagnet?
