N escalator in the subway station has a vertical rise of 195 ft 9.5 in., and rises at an angle of 10.4°. How long is the escalator? Round to the nearest foot.

Explanation:

Since the answer is supposed to be feet convert the inches to feet

The angle of rise is at the lower floor,so the vertical rise represents the opposite side of a right triangle.The length of the escalator is then hypotenuse of triangle

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.
