Jenna made an electric circuit as seen in the picture. She placed a thermometer near her light bulb. The light bulb was turned on for an hour. Select the most likely observation.
A) The bulb glowed brighter over time.
B) The temperature in the thermometer went up.
C) The temperature in the thermometer went down.
D) Both the light and temperature remained the same over time.

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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:

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
