How does the motion of the atoms in the spoon change when the spoon is placed in the hot coffee?
А
The atoms vibrate faster due to the conduction of heat through atoms in the spoon.
B
The atoms vibrate slower due to the conduction of heat through atoms in the spoon
С
The atoms move closer toward each other due to the radiation of heat through atoms in the spoon.
D
The atoms move away from each other due to the convection of heat through atoms in the spoon.

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:
