Write true or false for the following questions 1.Light is refracted when it enters or leaves a transparent material.
2.Dispersion is made up of all the colors of the spectrum, from red to violet
3.A light ray bends towards the normal when it passes from air into a transparent material.
4.White light happens because some colors of light are refracted more than others.
5.A light ray bends away from the normal when it passes from a transparent material into air.

i think they are all correct

explanation:

they seem good

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.
