The distance from the Sun to Mars is about 2.146 x 1011 meters.
The speed of light is approximately 2.9 x 108 meters per second.
Dr. Longshot wants to know how many seconds it will take for light to travel from the Sun to Mars.
She knows she can divide the distance by the speed to find this number.
Approximately how many seconds will it take for a beam of light to travel from the Sun to Mars?
Write your answer scientific notation
To find the number of seconds it will take for light to travel from the Sun to Mars, we divide the distance by the speed:
(2.146 x 10^11 meters) / (2.9 x 10^8 meters per second)
Simplifying the expression, we subtract the exponents:
2.146 / 2.9 x 10^(11-8) = 2.146 / 2.9 x 10^3
Calculating the division, we get:
= 0.739 x 10^3
In scientific notation, this can be written as approximately 7.39 x 10^2 seconds.
that is not correct
Apologies for the incorrect response. Let's calculate the correct answer.
The correct calculation is:
(2.146 x 10^11 meters) / (2.9 x 10^8 meters per second)
Dividing the numbers, we get:
≈ 7.410 x 10^2 seconds
Therefore, it will take approximately 7.410 x 10^2 seconds for a beam of light to travel from the Sun to Mars.
To find the number of seconds it will take for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light. Let's calculate it step by step:
Distance from the Sun to Mars: 2.146 x 10^11 meters
Speed of light: 2.9 x 10^8 meters per second
To divide the distance by the speed, we can use the formula:
Time = Distance / Speed
Plugging in the values:
Time = (2.146 x 10^11 meters) / (2.9 x 10^8 meters per second)
Now, when dividing numbers in scientific notation, we divide the coefficients and subtract the exponents:
Time = 2.146 / 2.9 x 10^(11 - 8) seconds
Simplifying the coefficient and exponent:
Time = 0.74 x 10^3 seconds
In scientific notation, this can be written as:
Time ≈ 7.4 x 10^2 seconds
Therefore, it will take approximately 7.4 x 10^2 seconds for a beam of light to travel from the Sun to Mars.
