Answer:
The correct option is;
C. 1 mile clear of clouds
Explanation:
Given that the indicated airspace location is at or below 700 feet AGL therefore, it is taken as being in the region of a class G airspace which covers the airspace regions from the base up to and equal to 1,200 feet beneath the class E airspace and the requirement for VFR flight for class G are 1 mile and clear of clouds.
Answer: Magnetic and gravitational force
Explanation: When a magnet and an iron nail are kept at a distance,the magnet attracts the nail without touching using magnetic force. In this example, the magnet and the nail are interacting.
The earth pulls the moon towards it and keeps it in orbit without touching it, using gravitational force. In this example,the moon and the earth are interacting.

Answer:
This distance is measured from the center of the earth r = 3.4 10⁸ m
Explanation:
The equation for gravitational attraction force is
F = G m1 m2 / r²
Where g is the universal gravitation constant, m are the masses of the body and r is the distance between them, remember that this force is always attractive
Let's write the sum of force on the ship and place the condition that is balanced
F1 -F2 = 0
F1 = F2
Let's write this equation for our case
G m Me / r² = G m Mm / (r'.)²
The distance r is measured from the center of the earth and the distance r' is measured from the center of the moon,
r' = 3.85 10⁸ m
Let's simplify and calculate the distance
Me / r² = Mm / / (3.85 108- r)²
Me / Mm (3.85 108- r)² = r²
√ 81.4 (3.85 108 -r) = r
√ 81.4 3.85 108 = r (1 + √ 81.4)
34.74 108 = r (10.02)
r = 34.74 10⁸ / 10.2
r = 3.4 10⁸ m
This distance is measured from the center of the earth

"<span>Give an example of a situation in which you would describe an object's position in (a) one-dimension coordinates (b) two-dimension coordinates (c) three-dimension coordinates"
Solution
(a) One dimension example: a man walking along a metal plank. We just need to specify one coordinate, the distance from the beginning of the plank.
(b) Two-dimension example: a ball moving on a circle. In this case, we need two coordinates: (x,y) to specify the position of the ball at every instant, since it is moving on a 2-D plane.
(c) The position of an airplane in the air: in this case we need 3 coordinates, the height, the latitude and the longitude of the airplane.</span>
To solve this problem we will apply the concept related to the electric field. The magnitude of each electric force with which a pair of determined charges at rest interacts has a relationship directly proportional to the product of the magnitude of both, but inversely proportional to the square of the segment that exists between them. Mathematically can be expressed as,
Here,
k = Coulomb's constant
V = Voltage
r = Distance
Replacing we have
Therefore the magnitude of the electric field is
