Answer:ball, ramp, and angle
Explanation: these are the three things that are controls because you can control them
Answer: Instantaneous speed.
Explanation:
m = mass of the penny
r = distance of the penny from the center of the turntable or axis of rotation
w = angular speed of rotation of turntable
F = centripetal force experienced by the penny
centripetal force "F" experienced by the penny of "m" at distance "r" from axis of rotation is given as
F = m r w²
in the above equation , mass of penny "m" and angular speed "w" of the turntable is same at all places. hence the centripetal force directly depends on the radius .
hence greater the distance from center , greater will be the centripetal force to remain in place.
So at the edge of the turntable , the penny experiences largest centripetal force to remain in place.
No, he should place the He atom and energy on the right, and the H atoms and the heat and energy on the left.
Explanation:
Write in scientific notation.
