In an inverse graph for wavelength versus frequency what are the units of the constant? would they be (cm/s)/hz or what?

centimeters per second (cm/s)

Explanation:

The relation between the frequency and the wavelenght is:

Velocity = wavelenght*frequency.

So in a relation of wavelenght vs frequency, we will have the relationship:

Where wavelenght is Y and frequency is X

wavelenght = velocity/frequency.

So the constant is the velocity, and we know that the units of the wavelenght is cm, the unit of frequency is Hz (or 1/s), so the units of the velocity is cm/s

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.
