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.

Hello!
Recall the period of an orbit is how long it takes the satellite to make a complete orbit around the earth. Essentially, this is the same as 'time' in the distance = speed * time equation. For an orbit, we can define these quantities: 
 ← The circumference of the orbit
 ← The circumference of the orbit 
speed = orbital speed, we will solve for this later
time = period 
Therefore: 

Where 'r' is the orbital radius of the satellite. 
First, let's solve for 'v' assuming a uniform orbit using the equation:

G = Gravitational Constant (6.67 × 10⁻¹¹ Nm²/kg²) 
m = mass of the earth (5.98 × 10²⁴ kg) 
r = radius of orbit (1.276 × 10⁷ m) 
Plug in the givens:

Now, we can solve for the period:

Answer:
Convergent plate boundary
Explanation:
The convergent plate boundary refers to the type of boundary where two plates move towards each other. Due to this type of motion, there forms a subduction zone, where the denser plate subducts below the lighter plate. This zone of subduction is commonly identified by the presence of a deep and narrow V-shaped depression which is commonly known as the oceanic trench.
When the subducting plate enters into the region of the asthenosphere, the rocks melt and mix with the magma. This magma is then pushed upward due to the force exerted by the convection current that forms in the mantle, and further reaches the over-riding plate and eventually give rise to the formation of volcanoes and volcanic/island arcs.
Thus, this type of plate boundary is responsible for the formation of above-ground volcanic activities.
 
        
             
        
        
        
Do you have any options? My guess would be distance but I could be wrong.
