Suppose that the metal cylinder were placed into a graduated cylinder filled with water, with markings of 1 ml, in order to find its volume by the amount of water it displaced, read to the nearest ±1 ml (note that i ml-1 cm) would this be less precise, more precise, or have approximately the same precision as calculating the volume from the given diameter and height measurements? 1 explain your reasoning.

If football was tossed in air without gravity or friction the ball would go into space

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

The correct choice is c

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
