Avector has an x-component of length 3.5 and a y-component of length 3. what is the angle of the vector? (hint: use the inverse tangent.) a. 59.0° b. 40.6° c. 31.0° d. 67.2°

ANSWER

EXPLANATION

A sketch of the vector is shown in the diagram in the attachment.

The side adjacent to the angle we want to find is 3.5 units and the opposite side is 3 units.

Let the angle between the vector and the x-axis be

then,

This implies that,

The correct answer is B

Therefore the angle 40.6° to the nearest tenth.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
