Answer:
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.
136g of iron oxide will be produced
Answer:
The correct answer is - 4.9 kg x m/s^2.
Explanation:
The weight of any object is the mass of the object in specific gravity applied to the object. It can be represented by the F=ma where F is the force applied on the earth by the gravity (a) and mass of the object (m).
Solution:
F = ma
F = 0.5*9.8 kg x m/s^2.
= 4.9 kg x m/s^2.
