For the transformation of Cu described in question 1, if nucleation were to instead occur on an internal structural inhomogeneity with a wetting angle of 45°, what would be the required undercooling to maintain an identical nucleation rate to solid Cu homogeneously nucleating at an undercooling of 200 o C?

d.) circle motion requires a force to give it a centripetal acceleration.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
