As she picks up her riders, a bus driver traverses four successive displacements represented by the expression
(-6 b)î - (3.70 b cos 40°)î - (3.70 b sin 40°)ĵ + (2.50 b cos 50°)î - (2.50 b sin 50°)ĵ - (4.90 b)ĵ
here b represents one city block, a convenient unit of distance of uniform size; î is east; and ĵ is north. the displacements at 40° and 50° represent travel on roadways in the city that are at these angles to the main east—west and north—south streets.†
(a) draw a map of the successive displacements.
(c) compute the magnitude and direction of her total displacement (counterclockwise from east).

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
