Answer» 1. one lumen per steradia2. Light-year is the distance light TRAVELS in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.3. Absolute zero the lowest temperature that is THEORETICALLY possible, at which the motion of PARTICLES which constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to −273.15°C.4. The least count of the screw is defined as the distance moved by the tip of the screw when turned through one division of the head scale.
