Work is done on an object only if the force and displacement are in the same direction.
Science can be used to address societal issues and to inform policies. Hope I Helped :)
If the drop is small enough, it is a perfect sphere.
<span> A sphere is the geometrical shape that has the smallest surface area for its volume. The drop takes this shape because water molecules tend to stick to each other. So, when not confined by a container, and with nothing around it to distort its shape, a very tiny water drop is perfectly round like a ball because the water molecules are pulling inward toward each other. </span>
<span>If the drop is larger like a raindrop in free-fall, it has a domed top and a semi-flattened bottom because as it falls it must push the air out of its way. That "upward" push of the air being displaced causes the falling drop to have a rather flattened bottom. </span>
<span>Contrary to popular misconception, a free-falling raindrop is not shaped like a teardrop -- round on the bottom and pointy on top.

Answer:
The correct answer is - option A. exaggerating them.
Explanation:
The extrapyramidal tracts forms or forms in the brainstem that brings the motor fibers that carry motor signals to the spinal cord. The extrapyramidal that are responsible for the regulation of the autonomic and involuntary control.
lesions in these system cause the exaggerating in the spinal reflexes that regulates the control of muscle tone, posture, and other actions, involuntary.
Thus, the correct answer is - option A.
