Answer: C (impulse acting on the object)
The momentum is defined as it is the impulse acting on the force . Change in momentum is known as Impulse. Impulse is used to increase or decrease the momentum of object.
From Newtons II law
F = m. a
= m. v/t <em>since a = rate of change of velocity.</em>
<em> </em>F . t = m . v
F . t is known as impulse momentum
Hi, the main difference between polarized light and unpolarized light is that polarized light has electric fields oscillating towards one direction when unpolarized light has electric fields oscillating in all directions. Hope this helps!

Answer:
ossicles (comprising of hammer, anvil, and stirrup)
Explanation:
The hammer, anvil and stirrup are also known as the malleus, incus, and stapes, respectively which are the part of the middle ear.
They transmit the sound vibrations from eardrum to cochlea by a level mechanism. The generate mechanical advantage by multiplying the force over a shorter distance from the input of a smaller force at a larger distance.
The one that does not involve chemical energy would be : C. Coasting downhill on a bike
This one requires physical energy, To be categorized as chemical energy, the bond of chemical compounds has to be released
Hope this helps
