The specific heat of copper is 0.385 j/g•°c. which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°c to 29°c? q = 0.75 g x 0.897 j/g•°c x 29°c q = 0.75 g x 0.385 j/g•°c x 22°c q = 0.75 g x 0.385 j/g•°c x 29°c q = 0.75 g x 0.897 j/g•°c x 22°c

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
