Answer:
A.) 411.6 Mega metres
B.) 411.6 × 10^18 Picometers
Explanation:
Given that One light-year is the distance light travels in one year. This distance is equal to 9461 1015 m.
After the sun, the star nearest to Earth is Alpha Centauri, which is about 4.35 light-years from Earth.
The distance travelled will be
Distance = 9461 1015 × 4.35
Distance = 411557915.3 m
To Express this distance in
a. megameters, divide the value by 1000000
411557915.3 / 1000000
411.5579153 Mega metre
411.6 Mega metres approximately
b. picometers, multiply by 10^12
That is, 411557915.3 × 10^12
411.6 × 10^18 Picometers
