Hmm. . . You can't modify the ball or the ramp. Those are two constraints that don't leave much room for improvement. Is changing the pitch angle of the ramp allowed? I suppose not. How about moving the ramp into a vacuum chamber? If you place the ramp and ball in a vacuum chamber and purge the air, you will eliminate -- or at least greatly reduce -- the friction due to air resistance. In a vacuum, the ball should roll down the ramp faster. How about blowing the ball down the ramp? Get behind the ball and, once it's rolling, blow hard! Better yet, get a hair blow-dryer and really give it a boost.
Outside exposed to the atmosphere. Needs Oxygen to decompose
Water outside evaporate faster.
anything that is with heat such as outside using thermal/solar energy from the sun or you can use the stove and microwave
Water is evaporated faster outside a refrigerator.
Water is not evaporated faster than anything.
It rots faster outside of a refridgerator.
Altering the vehicle's wheels from its original equipment can put stress on related parts.
Ice melts faster on the outside. This is because there is ice surrounding the middle keeping it from getting warm.
Plants should grow better in the sun, it is the main source of photosynthesis with water depending on the condition outside and inside.
Outside because it is more exposed to air
Chemical reactions in cells are faster than the same reactions outside cells.
It will evaporate faster outside because of the heat.
