Light travels at a speed 3x10^8 m/s. What distance does it travel in a time of 0.1s?
well, what's 0.1s * 3*10^8m/s ?
30,000,000
To calculate the distance light travels in a given time, we can use the formula:
Distance = Speed x Time
Given that the speed of light is 3x10^8 m/s and the time is 0.1s, we can substitute these values into the formula to find the distance:
Distance = (3x10^8 m/s) x (0.1s)
Distance = 3x10^7 m
Therefore, light travels a distance of 3x10^7 meters in 0.1 seconds.
To find the distance light travels in a given time, we can use the formula:
Distance = Speed × Time
In this case, the speed of light is given as 3 x 10^8 m/s, and the time is given as 0.1s. Substituting these values into the formula:
Distance = (3 x 10^8 m/s) × (0.1s)
To simplify this calculation, we can use scientific notation. Recall that when multiplying numbers in scientific notation, we multiply the coefficients and add the exponents:
Distance = 3 × 0.1 × 10^8 × 10^-1 m
Simplifying this further:
Distance = 0.3 × 10^8 × 10^-1 m
Multiplying the coefficients:
Distance = 0.3 × 10^8-1 m
Subtracting the exponents:
Distance = 0.3 × 10^7 m
Converting this back to standard notation, the distance light travels in 0.1s is:
Distance = 3 × 10^6 m
