Consider a cube of aluminum, 3.3 cm by 3.3 cm by 3.3 cm. Imagine that one face is initially at 25o C and the other face is at 20o C. At what rate will thermal energy be transferred through the cube

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
