An intelligent alien living on a planet in the solar system orbiting Alpha Centauri, the nearest star system to our Solar System in the Milky Way Galaxy, receives radio signals from Earth traveling at 186,421 miles/hour. The signal asks if the Alien likes McDonald Burgers. How long, in years, would it take for an Earthling to receive the answer back, Yes! (The distance from Earth to Alpha Centauri = 4.367 light years away, 1 light year 6.0 x 10" miles, and 1 year 365.2422 days) %3D %3D

A light year (LY) is the distance that light travels in one year. 1 LY = 9.46x1015 m. Suppose we have detected a planet that orbits a star that is 104 light years away. How many millions of years would it take us to get there if we used a modern rocket with a maximum speed of 20.0 km/s (about 45,000 mph)? Assume 3 sig figs.
17. The distance from earth to the nearest star is about 4 x 1016 meters. How long would it take a radio signal traveling at the speed of light, 3.0 x 108 m/s, to make a one-way trip to this star? 300 years 1 x 108 years 4 x 104 years 4 years 2 x 103 years
The speed of light in a vacuum is approximately 299,792,458 meters per second. Convert this speed to kilometers per hour (km/h). A) 107,925,284 km/h B) 1,079,252.84 km/h C) 299,792.458 km/h D) 1,079,252,840 km/h
All radio waves travel at the speed of light, 3.00×108 m/s. The frequency of a radio wave with a wavelength of 200 m is (a) 6E10 Hz (b) 1,500,000 kHz (c) 6.666667E-7 MHz (d) 1,500 kHz
The moon is 1.3 light-seconds away. Imagine you are standing at the Canadian Space Agency headquarters in St. Hubert, Quebec and you bounce a 755 MHz radio signal off the moon (the moon acts like a mirror, reflecting the signal, such that it comes back to you). How long will it take for that radio signal to get back to you on earth? Answer in seconds with one decimal place.
A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s). 1. 4 light-seconds 2. 3 light-minutes 3. 2 light-days 4. 2 light-days, but this time answer in miles (enter just the number with no units)
A radio transmitter broadcasts at a frequency of 127kHz. What is the wavelength of the wave? ( speed of light in vac-uum: c = 3 × 10 8 m/s ) Calculate to 1 decimal
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 42,000 km/hr to reach Alpha Centauri?
106x 103 x 1.701 x 1013 186 x 1.701 X 10 -10 -10 106,000 miles= 316.386 x 10 ' light years Exercise: One parsec is a unit of distance equal to roughly 3.25 light-years. The prefix Mega means "million." A star system 24 Mpc (Megaparsec) away from us in the direction of Orion is home to a hostile alien civilization intent on enslaving humans and forcing us to manufacture pizza sauce for their pleasure. What is the distance to these rapacious aliens in kilometers? Use your answer from the previous exercise. 000

If we send astronauts to Mars, there will be a time delay anytime we send or receive messages to them here on Earth. Given that Mars is an average of 54.6 million km away from Earth, how long is this time delay for a 2-way 'round-trip' communication - sent to Earth, then back to Mars? (this might be important in emergency situations) answer choices a)About 4 minutes. b)About 30 seconds. c)About 10 seconds. d)About 6 minutes.
The speed of light is 2.998*10^8 m/s. How far does light travel in 7.0 μs ? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.
