It means water treated or supplied gaseous oxygen
To solve this problem we will define the order of magnitude of both points, then we will obtain the radius and obtain the conclusion of the order of magnitude.
A nanosecond is one billionth of a second while and a millisecond is one millionth of a second
Therefore something that runs in nanoseconds is six times faster than something that runs in milliseconds
The answer is D.
Most of the rotational and orbital motions in the solar system are in the same "eastward" direction. Motions in this direction are referred to as direct motions while motions in the opposite direction are referred to as retrograde.
Retrograde motion is the apparent backward motion of a planet caused by its being lapped by another planet or vice versa. Both planet move in a direct eastward motion around the sun, but the planet with the inside (smaller) orbit moves faster than the planet on the outside (larger orbit), and when it passes the slower moving planet, each sees the other one as apparently moving backward relative to its motion around the sky.
