Abear, searching for food wanders 35.0 meters east then 20.0 meters north. calculate the angle of the bear's displacement (w/respect to his starting position).

north of east

Explanation:

Using a reference system in which east corresponds to the x-coordinate and north corresponds to the y-coordinate, the angle of the bear's displacement can be calculated by using the formula:

where

is the displacement along the y-direction

is the displacement along the x-direction

Substituting, we find

where the angle is measured with respect to the x-direction (east).

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
