Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 22.0 ∘ C at one end and 130 ∘ C at the other end. Both rods have a circular cross section with a diameter of 2.50 cm. Part A : Determine the length the rods must have if the combined rate of heat flow through them is to be 30.0 J per second.Please express answer in meters. Part B: If the length of the rods is doubled, by what factor does the rate of heat flow change?(Q final/Q initial)

Two square metal plates are placed parallel to each other, separated by a distance d= 2.28 cm. The plates have sides of length L = 0.690 m. One of the plates has charge Q= + 2.34×10-6 C, while the other plate has charge -Q. Calculate the magnitude of the electric field between the plates, not close to the edge, i.e., assume a uniform surface charge distribution.
