Have wavelengths that are longer than normal.
<span>It's close to the sun without much atmosphere, so it's characterized by </span><span>very extreme temperatures.
Happy studying ^_^</span>
We know, Mechanical Energy = K.E. + P.E.
As ball is at ground, P.E. would be zero. But as it is in motion, it must have some K.E. and that is:
K.E. = 1/2 mv²
K.E. = 1/2 * 1 * 2²
K.E. = 4/2
K.E. = 2 J
In short, Your Answer would be Option B
Hope this helps!
