8. When using the scientific notation system to express large numbers, move the decimal until one digit(s) remain(s) to the left, then indicate the number of moves of the decimal point as the power of 10.

9. b. Significant figures.

When significant figures are used, the digits are certain plus one uncertain digit.

10. a Kelvin scale, absolute zero.

The Kelvin scale runs to absolute zero which is the lowest theoretical temperature. This measures 0 Kelvins on the Kelvin scale and −273.15°C on the Celsius scale.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
