Juli2301 [7.4K]

\text{Hello there!}\\\\\text{We're trying to find displacement}\\\\\text{We would use the Pythagorean theorem to find the displacement:}\\a^2+b^2=c^2\\\\\text{We know that the car goes 20 km south and 20 km west}\\\\\text{When you draw it out, it should look like a triangle, you would be finding}\\\text{the length of the hypotenuse}\\\\\text{Plug in 20 to} \,\,a^2\,\, \text{and}\,\, b^2}\\\\20^2+20^2=c^2\\\\\text{Solve:}\\\\20^2+20^2=c^2\\\\400+400=c^2\\\\800=c^2\\\\\sqrt800=\sqrt c\\

Which order shows increasing energy of photons?
Alchen [17]

The correct answer is C. microwaves, infrared, visible, gamma rays

Electromagnetic waves arranged in order of  frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.

Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.

According to the Einsteins equation, E=hf, Energy is  directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.

Who discovered laws of gravity and motion? He discovered aspects of light and color, leading to today's spectrum analysis
Vitek1552 [10]

Answer:

Sir Isaac Newton

Explanation:

The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.

In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
