8. A box contains 5.125X10^4 thumb tucks. The mass of each thumb tuck is

8.1X10^-6 kilograms. What is the combined mass of the thumb tucks in

the box?

9. A microscope is set so it makes an object appear 4.3X10^3 times larger

than its usual size. A virus has a diameter of 2.7X10^-8 meter. How large

will the diameter of the virus appear when it is viewed under the

microscope?

10. 1.2 yottameter to yoctometer

Answer 1

7.

$$\dfrac{3.1\times10^8}{4.12\times10^7}\approx7.524\ times$$

8.

$$5.125\times10^4(8.1\times10^{-6}kg)=0.415125kg$$

9.

$$4.1\times10^3(2.7\times10^{-8}m)=1.107\times10^{-4}m$$

10.

1 yottameter = $10^{48}$ yoctometer

1.2 yottameter = $1.2\times10^{48}$ yoctometer
