- While a meter is the fundamental unit of length, most distances traveled by humans are measured in miles or kilometers. Why do you think this is?In 1983, at its General Conference on Weights and Measures, the National Institute of Standards and Technology used the speed of light to define the length of a meter. One meter is the distance light 1 travels in second. 299,792,458 a. How many meters does light travel in 1 second? Light travels | m. b. What is the speed of light in kilometers per second? The speed of light is km/sec. c. In England in 1956, the speed of light was meașured as 299,792.4 ± 0.11 kilometers per second. Is the speed of light that was used by the General Conference on Weights and Measures within this range? The speed of light (select) within.this range.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.
- 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 yearsThe speed of light is 2.998*10^8 m/s. How far does light travel in 6.0 μs? Set the math up. But don't do any of it. Just leave your answer as a math expression. be sure your answer includes all the correct unit symbols.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.
- Using a single dimensional equation, estimate the number of steps it would take a person with a step length of 2.65 ft to walk from the Earth to Alpha Centauri a distance of 4.37 light-years. The speed of light is 1.86282 x 105 miles/s.

- Speed = distance / time. The letter "c" is used to represent the speed of light. c = d / t Assuming that the difference in the light travel time between the two dates was 7.6 minutes and that 1.00 AU = 150,000,000 km determine the speed of light. a. 299,000,000 km/s b. 299,000,000 m/s c. 299,000 AU/minute d. 299 AU/sI'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.(the complete question is in the picture) If the Newtonian constant has units G = [N · m2/kg2], the speed of light has units c = [m/s], the mass has units M = [kg] and the SI unit newtons is equivalentto N = [kg · m/s2], what are the units of the relation GM/c3?A. [kg · s]B. [kg · m2/s]C. [m2/s]D. [s]
