Because fire does not burn down, it burns up and it therefore catches things above it on fire and it spreads that way. Also the wind current aids in it's spread.
earthworms travel faster
The wavelength that will cause electrons to travel faster when hitting uranium is 100nm. If the wavelength was any lower, electrons would not move as fast.
Faster in rock. the higher the density, the higher the speed.
Leptons have mass.According to special relativity, no particle with mass can travel at or faster than the speed of light. It would take infinite energy to do so.
The seismic waves of an earthquake travel faster than the winds of a tornado. But this is not what makes earthquakes destructive.
No the can go faster downhill or uphill
uphill, for an experiment look for "Do forest fires move faster uphill or down hill
Travel speed, as it is called, should be the same in all welding positions. Travel speed determines the size of the weld.
because if you going down hill its faster because its a mountain
Honestly I don't have any facts to back this up. but I believe that snails travel faster downhill due to the fact that gravity is assisting them. Considering the method of which they travel ( by sliding over slime ) I would think you could move faster downhill as you would not have to push against gravity to move up.
a bike downhill horse uphill
gravity!
It requires extra power to go uphill, against the pull of gravity.
It travesl by motion
No, actually, you shouldn't be passing on an uphill, at all.
because smoke rises and it travels better that way. fire is not something that moves, it spreads and will travel up hill cuz its tall and is already there.
If the cart is rolling downhill it will roll faster with mass, but on level ground or uphill it will roll faster without mass.
