The diffusion coefficients for copper diffusing in gold are given at two temperatures (hint: logarithm):(a) Determine the values of D0and the activation energy Qd?(b) What is the magnitude of D at 1100°C?

Explanation:

Below is an attachment containing the solution.

d

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
