1 parsec is equal to Physics Questions
WebThe light covers a distance of 9.461 10¹⁵ m in a year. Hence, 1 light year = 9.461 10¹⁵ m. 1 m (meter) = 10⁻³ km (kilometer) Thus, 9.461 10¹⁵ m = (9.461 10¹⁵ m) (10⁻³ km / m) = 9461000000000 km. In the standard form, 9461000000000 km is represented as 9.461 10¹² km. Thus, 1 light year = 9.461 10¹² km. WebA light-year is defined as the distance that light can travel in 1 year. We can calculate this by multiplying the speed of light by 1 year (or 3.1557*10^7 seconds) to find the distance: d = c*t = (2.9979*10^8 m/s)* (3.1557*10^7 s) =9.4605*10^15 meters or ~9,500,000,000,000 kilometers or ~5,900,000,000,000 miles or ~63,279 au (ad nauseum) Web02. jul 2024. · A light year is a simple form of measurement, being the distance light travels in one year of time.
