Answer:
False.
Explanation:
Power may be defined as the rate of doing work with time. The S.I. unit of power is J/s or watt. The power is a scalar quantity as it has only magnitude and no direction.
The power can be calculated by the formula:
Power = work done/ time taken.
From the formula, it is clear that power is inversely proportional to the time taken by the body. Hence, if the work remains constant, power will decrease with time.
Thus, the answer is false.
Answer:
The correct answer is B)Deep petrosal nerve
Explanation:
Postganglionic sympathetic fibers in the nerve of the pterygoid canal originate from the deep petrosal nerve. This corresponds to an internal carotid plexus and is formed by postganglionic fibers of the upper cervical ganglion; transports sympathetic postganglionic fibers directed to the blood vessels.
Answer:
The answer is the Pulmonary Artery.
Explanation:
