Answer from: 622ghernandezc

Unit of acceleration is not Km/s. Therefore, option D is the correct answer.

Kilometer (Km) is the unit of length and second (s) is the unit of time. Length/time is speed. Therefore, km/s is the unit of speed. Acceleration is defined as the rate of change of velocity with respect to time. It is vector quantity. Acceleration = velocity / time .Unit of acceleration=unit of velocity/unit of time .Unit of acceleration will be km/s2, km/hr2, m/s2.

Thus, we can conclude that Km/s is not the unit of acceleration. Therefore, option D is the correct answer.

Answer from: JadeK4853

An acceleration unit needs a unit of length or distance on top and a unit of (time · time) on the bottom. Let's go through the list:

- km/hr/s = (km) / (hr · sec) . . . Yes

- km/hr/hr = (km) / (hr · hr) . . . Yes

- m/s² = (m) / (sec · sec) . . . Yes

- km/s = (km) / (sec) . . . No . . . This is the only one that's NOT acceleration. This one is actually a unit of speed .

- m/s/s = (m) / (s · s) . . . Yes

Answer from: Quest

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
