Match each projection to its description.
a. cylindrical projection
b. planar projection
1. often, the center of the map is either the north or south pole.
2. the map is distorted near the poles.

A-2

B-1

Explanation:

Cylindrical projection is a type of map projection that projects the earth's surface on a cylindrical tangent. It is useful in projecting the equatorial region and the near-polar region but it gets distorted at the poles. This distortion occurs in terms of both the scale and the shape.

Planar projection is a type of map projection in which the three-dimensional earth's surface is projected on a flat surface. It is more efficient in mapping the polar regions. The North pole or the South Pole in this type of map are located at the center of the map.

Thus, the correct answers are being matched.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
