Albert is on earth and measures the speed of light from the sun as 3 e8 m/s. he then gets in a spaceship and speed toward the sun at 1 x e8 m/s. he will then measure the speed of light as 2 e8 m/s 3 e8 m/s 4 e8 m/s none of the above

The speed of light remains the same.

Explanation:

It is given that, Albert is on Earth and measures the speed of light from the sun as 3 × 10⁸ m/s. He then gets in a spaceship and speed toward the sun with a speed of 1 × 10⁸ m/s.

In this case, the speed of light remains the same i.e. 3 × 10⁸ m/s. It is a universal constant. Albert Einstein was the first scientist who has written his first research paper on relativity. According to him, the speed of light remains the same. It does not depend on how fast the observer moves.

Hence, the correct option is (b).

the higher the current the higher the mag field around it the higher the influence on the compass

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
