b. How many meters are equivalent to 7,200 yards? Round your answer to the nearest hundredth, if necessary.

7. Write an equation to find the “Number of people who know” for any 5-minute interval in Scenario B.

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

G. Use the concept of chemical potential energy to summarize why chlorophyll absorbs the wavelengths of light it does.

Gamma: this is a ray of electric radiations this is a part of electromagnetic spectrum. In the high energy and low wave frequency part. When ionising gamma rays pass through gamma because they are weak, travel through space and vacuum.

When light from a hot solid, liquid, or dense gas passes through a cooler gas, it will produce a/an _________ spectrum.

The propagation delay = 2d x (20ms/km) = (2x10) x (20ms/km) = 0.4 seconds or 400 ms.

1. In remote sensing, most units are expressed using the metric system. For example, the near infrared region of the spectrum is comprised of electromagnetic radiation of wavelengths extending from about 0.7-1.4m. Express this range in: meters using scientific notation (i.e., #.# x 10n m), and in nanometers. (1)

What are the apparent and absolute magnitudes of the Sun? What does it mean that they are not the same?

The atmosphere is divided vertically into four layers on the basis of temperature. List these layers in order from lowest to highest. In which

2. (5 points) How long does light take to travel to the Earth from the moon?

* f = c / λ (where c is the speed of light: 3 x 108 meters / second)

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

“A satellite orbiting the earth in a circular path stays at a constant altitude of 100 kilometers throughout its orbit. Given that the radius of the earth is 6370 kilometers, find the approximate distance that the satellite travels in completing 70% of one complete orbit.”

Some of the scientific data that follows was taken out of Cattermole's book. The mean distance from the sun is 108.20 Km.
