QUESTION:
Carry out the following conversions:
(a) 1.42 light-years to miles (a light-year is an astronomical measure of distance—the distance traveled by light in a year, or 365 days; the speed of light is \(3.00 \times 10^{8}\) m/s).
(b) 32.4 yd to centimeters
(c) \(3.0 \times 10^{10}\) cm/s to ft/s.
ANSWER:
Step 1 of 3
Here we have to do the following conversion.
(a) 1.42 light- years to miles
It is known that 1 light year is equal to \(5.879 \times 10^{12}\) mile
Hence 1.42 light year will be equal to \(=\left(5.879 \times 10^{12}\right) \times 1.42=8.34 \times 10^{12}\) mile
light year is equal to \(8.34 \times 10^{12}\) mile.
