There’s no picture and what’s the length?
Answer is E
time can be negative.
A is not true because <span>a=<span><span><span>d2</span>x</span><span>d<span>t2</span></span></span>=12 m/<span>s2</span></span>
C: question already said that particle move along x-axis, which is not parabola path.
D: velocity is <span><span><span>dx</span><span>dt</span></span>=12t</span>, therefore velocity changes by 12 m/s and not 9.8 m/s
So we are left with E.

A). No. A mirror doesn't separate light into its different wavelengths.
B). No. Light doesn't separate into its different wavelengths when it
goes, say, from glass into water.
C). No. When light goes through your glasses, it doesn't separate
into its different wavelengths.
D). Yes ! When sunlight shines into droplets of water in the atmosphere,
it comes out separated into its different wavelengths. When we see that
happening in the air in front of us, we call it a "rainbow".
Answer:
Both forces act along the line joining the objects like masses or charges. And both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law.
