Question

How many seconds are there in a leap year
If the velocity of light is 30 x 10 metres per second, calculate the distance travelled
hght in a light year and express it in standard form.
Distance travelled by light in a year!​

Answer 1

Answer:

Step-by-step explanation:

2 x 1010 or 20 x 109 = 20 Billion. A light-year is the distance light travels in one year. If light travels at a speed of 186,000 miles/second how many miles are there in a light-year? ... But the speed is not given in years, so we need to convert it into seconds. ... The Sun's actual size is (1.5 x 106 km) x (103 m/km) = 1.5 x 109 m
