Would a toy car go faster or slower down a ramp with sandpaper compared to a ramp with no sandpaper?

-- Steeper ramp.
-- Lower friction in the wheel and axle bearings of the car.
-- Better aerodynamic streamlining of the shape of the car.
-- Make the car of iron and conceal a large magnet at the bottom of the ramp.

How fast does water put out fire compared to sand?
Water would take longer because it is a liquid. Sand would put it out faster
What happens when the speed of a stream increases?
Things that would cause a stream to move faster would be how large the stream is, how much material is in the stream and how much of a slope the stream is at. Things blocking the stream would also cause it to move slower.
Which will roll faster down an inclined plane a can of water or a can of ice?
I think it would be ice in can. Coz it has low density and may have less friction as compared to water. Great and briallant question but i fear that my answer is wrong...
Which is faster 60km or 60 miles per hour?
Since kilometers are bigger than miles, 60 km per hour would be faster
Would you expect the particles in chlorine gas to diffuse faster or slower than the particles in argon gas?
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
If water was boiled an a saucepan would water be evaportated faster or slower than water that is not heated?
it would be faster
How would you determine if an object is accelerating?
It moves faster or slower
Why does sound travell faster under water than under ground?
Actually, sound travels slower under water than underground. Sound is a vibration in molecules that we perceive as noise. Water's molecules are rather loose compared to a solid's molecules, so it would travel slower underwater compared to traveling underground.
Would ink dissolve faster or slower in warm water?
Faster. Because the hotter/warmer the substance, the faster ink or any other material would dissolve in it.
Which would be a better conductor something that heats up quicker or slower?
Faster
When you add energy to the particles move?
faster. and matter then would move slower
Is a sea horse slower than a tortoise?
No, if a seahorse is frightened it would be faster, it is just slower than most other fish.
When a river floods would its water flow faster or slower than its normal speed?
When a river floods it water will flow faster then the normal speed.
What would be affected if a planet orbits the sun faster or slower?
The length of the planet's year would be affected.
Would a planet that has a longer day spin faster or slower than earth?
yes it does
When you add energy to matter particles move?
faster. and matter then would move slower
Would rocks on the moon weather faster or slower than on earth?
They would weather slower than on earth due to different amts of wind and rain than on earth.
