Answer & Explanation:
A girl is driving a bicycle at a velocity of 30m/s at 40 degree North west.
Considering the above sentence, the magnitude of the bicycle velocity is 30 meters per second and the direction of the motion of the bicycle is 40 degree North west. So, the bicycle is having both magnitude and direction, so the velocity is a vector quantity.
The most significant change in the comet's energy as it moves from point D to point A KE increases, GPE decreases.Option C is correct.
<h3>What are comets?</h3>
Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice.
They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a plane.
As the comet transitions from point D to point A, the biggest energy shift is seen. GPE declines as KE rises. The right answer is C.
Hence option C is correct.

Explanation:
If the micrometer is still in the working condition, it will be hard for the observer to find its accuracy or precision, which could be matched with the meter stick. Its accuracy can be compromised in comparison with the undamaged micrometer, but it would be more chances of highly precise.
The error which is find in the damaged micrometer would be less than as compared to the width of the hash marks on the stick.
Answer:
as the mass of an object is increased, the acceleration of the object is decreased & vice-versa.
