Why does Milli mean thousand?
Milli- (symbol m) is a unit prefix in the metric system denoting a factor of one thousandth (10−3). Proposed in 1793 and adopted in 1795, the prefix comes from the Latin mille, meaning “one thousand” (the Latin plural is milia).

How is a kilogram determined?
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10-34 when expressed in the unit J s, which is equal to kg m2 s -1 , where the meter and the second are defined in terms of c and ∆νCs.
What are 5 interesting facts about gravity?
Six weighty facts about gravity
- Gravity is by far the weakest force we know.
- Gravity and weight are not the same thing.
- Gravity makes waves that move at light speed.
- Explaining the microscopic behavior of gravity has thrown researchers for a loop.
- Gravity might be carried by massless particles called gravitons.
What will happen if there is no sun?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.
Can humans survive without sunlight?
Humans get our energy from the food we eat, and all of that food is derived from the energy of the sun. Submariners have gone without sunlight for periods exceeding 6-months, using vitamin D supplements. It is unlikely, though, that an adult could die directly and exclusively from prolonged darkness.
How much life is left in the sun?
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. Humanity may be long gone by then, or perhaps we’ll have already colonized another planet.
