Question

Divide 0.0081 meters by 300 seconds and express the answer in scientific notation,

Answer 1

2.7 X 10⁻⁵

Explanation:

0.000027/ 300 = 0.000027

but we have to move the decimal point to the right just after the first number different to zero, in this example is number 2.

Finally, as we move the point to the right, the power is negative.

Then the result is 2.7 x 10⁻⁵

Answer 2

Step-by-step explanation:

0.0081 meters by 300 seconds = 0.0081/300= 0.000027 m/s

= 2.7 ×10^-5 m/s
