Question

The team monitoring a space probe exploring the outer solar system finds that radio transmissions from the probe take 2.58 hours to reach earth. How distant (in meters) is the probe? m In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. The distance to Alpha Centauri, the closest star other than our own sun that can be seen by the naked eye, is about 4.1 light-years. Express this distance in meters. m A truck driver is broadcasting at a frequency of 27.405 MHz with a CB (citizen's band) radio. Determine the wavelength of the electromagnetic wave being used. The speed of light is $c = 2.9979 \times 10^8$ m/s. m

Astronomers use a light-year to measure distance. A light-year is the distance light travels in one year. The speed of light is approximately 300,000 km/sec. a. How long is 1 light-year in kilometers? b. The nearest star (other than the sun) is Alpha Centauri. It is 4.34 light-years from Earth. How far is that in kilometers? c. How long will it take a rocket traveling 44,000 km/hr to reach Alpha Centauri? a. 1 light-year = kilometers (Use scientific notation. Use the multiplication symbol in the math palette as needed. Do not round until the final answer. Then round to the nearest hundredth as needed.) b. 4.34 light-years = km (Use the answer from part a to find this answer. Use scientific notation. Use the multiplication symbol in the math palette as needed. Type an integer or decimal rounded to the nearest hundredth as needed.) c. It will take hours to reach Alpha Centauri. (Use the answer from part b to find this answer. Use scientific notation. Use the multiplication symbol in the math palette as needed. Type an integer or decimal rounded to the nearest hundredth as needed.)

1. (5p) Light travels a distance of about 3.00 ! 10⁸ m in 1 s. A light-minute is the distance light travels in 1 min. If the Sun is 1.5 ! 10!! m from Earth, how far away is it in light-minutes? Show your work. A numerical value is required for credit. 2. (5p) The average distance between Earth and Sun is 1.496 ! 10!! m, and Earth’s orbit is considered a circle. Calculate the average velocity of Earth moving around the Sun for exactly one year (365.25 days). Explain your answer. A numerical value is required for credit.

The star Alpha Centauri A is at a distance from us of 4.4 light-years and has an apparent brightness as seen from Earth of 2.7 x 10^8 Watts/m^2. Recall that 1 light year is 9.5 x 10^15 m. (a) Use this inverse square law of light to calculate the intrinsic luminosity of Alpha Centauri A. (b) Suppose you have a light bulb that emits 100 Watts of visible light. How far away would you have to put the light bulb for it to have the same apparent brightness as Alpha Centauri A does in our sky? (Hint: Use 100 Watts as L in the inverse square-law and use the apparent brightness given above for Alpha Centauri A, then solve for distance). [20 pts]

00:01 So how long is one light year in kilometers? so we know the speed of light is 300 ,000 kilometers per second.
00:10 We want to find out how long that is in gears.
00:14 So the amount of seconds in one day is 60 seconds times 20, 60 seconds, which would give us 60 seconds gives us one minute, 60 minutes gives us one hour, 24, what? 24 hours gives us one day and 365 days gives us one year.
00:50 Oh, shoot.
00:59 There we go.
01:00 Now we'll tell us how many kilometers is in one light year.
01:03 So we do that calculation and we're going to get a huge number.
01:18 We get 9 .46 times 10 to the 12 meters...
