If it takes the bird 15 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive.

Incomplete question.The complete question is here

A seagull can fly at a velocity of 9.00 m/s in still air.If it takes the bird 15 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive.

Explanation:

Given data

The velocity of bird:

Assume that:

The bird feels the air stream is equal in opposite direction  or:

According to the relative motion concept the velocity of wind VAE is given by:

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.

it doesn't. it was imagined up in the middle ages.
