Colors seen on the cover of our physics book result from color is due to Subtraction.
What is physics of color subtraction?
- Some visible spectrum wavelengths are intentionally removed during the subtraction procedure.
- For instance, the yellow filter transmits the green and red colors while blocking the blue.
- Red and blue are transmitted while the green is blocked by the magenta filter.
- Blue and green are transmitted while red is blocked by the cyan filter.
- Subtractive mixing gets its name from the fact that when colors are mixed, wavelengths are removed from what we see because each paint absorbs some of the wavelengths that the other paint reflects, leaving us with less wavelengths afterward.

Answer:
f=1/t is the equation of frqency
C. The object is accelerating as the direction of the object is changing
The second Newton's law of motion states that the rate of change in momentum of a moving body is proportional to the resultant force.
Therefore, to understand this law one must understand the concept of momentum and that a body in motion experiences force.
As far as momentum is concerned it is important to note that as a body moves the momentum changes with change in time and also that a body at rest has 0 momentum because its speed/velocity is zero.
It is this change in momentum with time that is proportional to the resultant force experienced by the body.
