The second species in any environment.
It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
It is a property which was discovered by Newton. In it a thing gains speed automatically while it is being put in effort from a ramp, or thrown from height. It get it's speed from gravity.(Gravity has three properties, one is acceleration).
When did he discovered? Do you mean what? He discovered Yellow Fever was transmitted by mosquitoes. And if you mean when did he discover it, then the answer you are looking for is he led a research team that discovered this in 1900.
J.J.Thomson has discovered the electron in 1897
It is not known where exactly in England sodium was discovered. It was discovered by Sir Humphrey Davy in 1807.
Alexander Fleming discovered penicillin in 1928
not sure
he discovered the speed of light
This is because nothing else in the entire discovered universe moves as fast as the speed of light!
Einstein
"Speed" & "Velocity" are the same thing, they were not "invented" but discovered so to speak through Theoretical physics.
Olaus Roemer discovered the speed light in 1676.
it was MAxwell the dude who discovered electromagnetic waves
A German physicist. He discovered a method for working out the speed of sound in different gases.
If a dwarf planet were discovered farther from the Sun than Eris, its orbital speed would be slower than that of Eris. According to Kepler's laws of planetary motion, the farther an object is from the Sun, the slower its orbital speed due to the weaker gravitational pull. Thus, this newly discovered dwarf planet would have a longer orbital period and a reduced speed compared to Eris.
probably all kinds of technology
... its speed is the same in any direction, even if you're movingin that direction or in the direction opposite to it.
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
