Given:

The signal from a certain satellite takes approximately 0.0029 seconds to reach earth.

we will write the number in a scientific notation

The scientific notation is the number that is between 1 and 9 multiplied by 10 raised to an exponent

So, the given number will be:

`0.0029=(29)/(10000)=(29)/(10)*(1)/(1000)=2.9*10^(-3)`
