For an object to appear red, what must the object do to red light waves? a. it must bend them b. it must absorb them c. it must reflect them d. it must shift them

The answer is C. It must reflect them

Any light that is absorbed by an object will not be visible, only light that is reflected by the object is visible.

Explanation:

Light consists of colors Violet, Indigo, Blue, Green, Yellow, Orange and Red. If we are seeing a color, it is decided by which color are absorbed and reflected by the object. The color of the object is reflected by the object other colors are absorbed by the object.

Here object appears in red color so red color is reflected by the object and other colors are absorbed.

Option C is the correct answer.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
