the speed of light is 3 × 10^8 meters per second. what is this speed in standard form?\na. 300,000,000…

Explanation:

Step1: Recall scientific - to - standard conversion

The scientific notation $a\times10^{n}$ (where $1\leqslant a<10$ and $n$ is an integer) is converted to standard form by moving the decimal point in $a$ $n$ places. If $n>0$, we move the decimal point to the right. For $3\times 10^{8}$, since $n = 8$, we move the decimal point in 3 eight places to the right.

Step2: Perform the movement

Starting with 3, moving the decimal point 8 places to the right gives 300000000.

Answer:

A. 300,000,000 meters per second
