Answer:
So airplane will be 1324.9453 m apart after 2.9 hour
Explanation:
So if we draw the vectors of a 2d graph we see that the difference in angles is = 83 - 44.3 = 
Distance traveled by first plane = 730×2.9 = 2117 m
And distance traveled by second plane = 590×2.9 = 1711 m
We represent these distances as two sides of the triangle, and the distance between the planes as the side opposing the angle 38.7.
Using the law of cosine, 
representing the distance between the planes, we see that:
d = 1324.9453 m
Bohr’s model showed that electron orbits had distinct radii.

All of the factors that need to be considered when determining an object's terminal velocity are the object's weight and area it presents, as well as air density.
<em>option </em><em>C </em><em>is the correct answer</em>
<h3>What is terminal velocity?</h3>
Terminal velocity is obtained when the speed of a moving object is no longer increasing or decreasing. That is the object's acceleration (or deceleration) is zero.
Mathematically, the formula for terminal velocity is given as;
V = √(2mg)/(ρAC)
where;
- m is the mass of the falling object
- g is the acceleration due to gravity
- ρ is the density of the fluid through which the object is falling
- A is the projected area of the object
- C is the drag coefficient
Thus, the variables to consider in determining terminal velocity of an object incudes the area, density of air, mass, etc.
