Light travels at an approximate rate of 1.9. x 10^5 mi/sec. There are about 3.2 x 10^7 seconds in a year. About how many miles does light travel in a year? Write the answer in scientific notation. Express the answer to the exact decimal place
To find out how many miles light travels in a year, we need to multiply the rate of light by the number of seconds in a year.
Rate of light = 1.9 x 10^5 mi/sec
Number of seconds in a year = 3.2 x 10^7 sec
Now we can calculate the total distance traveled by light in a year:
Total distance = Rate of light x Number of seconds in a year
Total distance = (1.9 x 10^5 mi/sec) x (3.2 x 10^7 sec)
To multiply values in scientific notation, we multiply the coefficients and add the exponents:
Total distance = (1.9 x 3.2) x (10^5 x 10^7) mi
Total distance = 6.08 x 10^12 mi
Therefore, light travels approximately 6.08 x 10^12 miles in a year.
To calculate the total distance traveled by light in a year, we multiply the speed of light by the number of seconds in a year.
Speed of light = 1.9 x 10^5 mi/sec
Number of seconds in a year = 3.2 x 10^7 seconds
The total distance traveled is:
(1.9 x 10^5 mi/sec) * (3.2 x 10^7 seconds)
To multiply the values in scientific notation, we multiply the coefficients and add the exponents:
1.9 * 3.2 = 6.08
10^5 * 10^7 = 10^(5+7) = 10^12
Therefore, the distance light travels in a year is 6.08 x 10^12 miles.
To find out how many miles light travels in a year, we need to multiply the velocity of light (1.9 x 10^5 mi/sec) by the number of seconds in a year (3.2 x 10^7 seconds).
To do this calculation, we can use the rules of scientific notation:
1. Multiply the coefficients: 1.9 x 3.2 = 6.08.
2. Add the exponents: (10^5) x (10^7) = 10^(5+7) = 10^12.
3. Put the result in scientific notation: 6.08 x 10^12.
Therefore, light travels approximately 6.08 x 10^12 miles in a year.
wrong
Apologies for the confusion. Let's re-calculate the total distance traveled by light in a year.
Speed of light = 1.9 x 10^5 mi/sec
Number of seconds in a year = 3.2 x 10^7 seconds
To find the total distance, we multiply the speed of light by the number of seconds in a year:
(1.9 x 10^5 mi/sec) * (3.2 x 10^7 sec)
To multiply these values in scientific notation, we multiply the coefficients and add the exponents:
1.9 * 3.2 = 6.08
10^5 * 10^7 = 10^(5+7) = 10^12
Therefore, the distance light travels in a year is 6.08 x 10^12 mi.
