How much time does it take light to travel from the moon to the earth, a distance of 384000 km ? Correct answer= 1.28 secs Light from the star α Centaurus takes 4.30 years to reach the earth. What is the distance to α Centaurus in kilometers? please answer with 3 significant figures and km for units
) Distance from Earth to Moon is about 2.39×105 miles. Assuming that a spacecraft can take off from Earth, attain escape velocity (see part (C)) and directly get to the Moon and land, what would be the time taken for travel to the Moon? Apollo 11 astronauts reached Moon in 4 days, 6 hours and 45 minutes in July 1969. It is not really practical to go to Moon in one shot. One way is to get a craft to...
A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 7.03 x 107 km. Radio waves travel at the speed of light (3.00 108 m/s). How many seconds does it take for the signal to reach the Earth?

An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.270 × 105 km and the planet has a radius of 3.150 × 103 km and a mass of 6.55 x 1022 kg, how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67 x 10lN-m2/kg2 T-0.88125...
You are an observer in a 100-m long spacecraft traveling from the earth to the moon at 0.8c. (a) What is the proper length of the spacecraft?

T/F? (d) What is the relativistic length, DL measured from the reference frame of earth? (e)...
-10. A car traveling at 40.0 mi/h skids to rest in 5.00 s. (a) What is its average speed during the stopping pro- cess? (b) How far does it go during the stopping process? 3-11. (a) How long does it take sunlight to reach the earth? (The sun is 9.30 x 10" mi away; the velocity of light is 186,000 mi/s.) (b) Moonlight? (The moon is 2.40 x 105 mi from the earth.)
