A certain object is subject to two forces: a 10-N force straight up and a 10-N force straight down. A student states that since both forces are in the vertical direction, the object cannot be moving horizontally. Why is this an incorrect conclusion?
A.
The vertical forces are balanced.
B.
Vertical net forces can cause horizontal motion.
C.
A horizontal force is not required for horizontal movement.
D.
Two vertical forces can combine to form a horizontal resultant force.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

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:
