The answer is C
The colour that you see is what is being reflected and the colour that you don't see is what is being absorbed. In this case, you don't see any colour, so all wavelengths are being absorbed.
Kinetic energy is the energy possessed by an object having some mass and moving at some speed due to its motion. Kinetic energy is given as
KE = (0.5) m v²
where KE = kinetic energy
m = mass of the object in motion
v = speed of the object in motion.
it is a scalar quantity and has only magnitude and no direction.

Answer:
Relative Error = 0.0001%
Explanation:
What is Relative Error?
This is the ratio of the absolute error of a measurement to the measurement being taken. Relative Error is expressed as a percentage and has no units.
Given data
Weight of purchased apples= 19kg
RE = 0.0021/19
RE= 0.0001%
Hence the Relative Error is 0.0001%
