How would I convert 3x10^-9s to ms? Would I change the 3x10^-9 to an actual number, or keep it in...?

Question

scientific notation?
that darn physics again, I have a quiz tommorow

Answer 1

Keep it in scientific- you would multiply by 1000, so you increase the exponent by three-(the number of zeros) (BE CAREFUL-the exponent is negative, so it goes from -9 to -6) To go the other way, you divide by 1000, so you would take away three zeros.

Answer 2

One of fundamental rules in physics is that you have to use a scientific notation to keep the exact number of significant figures.
So 3 x 10^-9 s = 3 x 10^-9 x 10^3 ms = 3 x 10^-6 ms
A physicsist would never write this as 0.000 003 ms :-)

Answer 3

The m in ms is milli or one over 1000 or 10^-3

So 10^-9 s is (10^-6)(10^-3)s or 10^-6 ms

Until you get comfortable with the math, think logically. Milliseconds are smaller than seconds.

There need more of them to describe the same time.

10^-6 (one over a million) is 1000 times more than 10^-9 (one over a billion), so that's the answer you want.

Answer 4

multiply by 3, 3*10^-6
