What is the sleek shape of a bobsled reduces and allows greater speeds
Air resistance
It allows a greater range of speeds, increase performance and fuel economy.
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds
it speeds up water uptake and reduces germination times
Their cores are spinning faster.
Known as Maglev (derived from magnetic levitation), it is a method of using magnets to raise a train above the ground, and in propulsion. This reduces friction by a great extent and allows for very high speeds.

... of the same substance, yes. As, in a gas the molecules are spaced farther apart and move around at greater speeds.
Flaps increase the aerodynamic lift of a wing by increasing it's surface area. This allows the airplane to generate a greater amount of lift at slower speeds. In other words, when the flaps are extended, the airplane doesn't have to go as fast in order to take off or land. The flaps are retracted once the airplane is off the ground and has increased its speed to a point where the extra lift from the flaps is no longer needed. Flaps also have the effect of increasing drag on the airplane wing which reduces the airplane's speed and efficiency, but this only affects the aircraft when operating at higher speeds.
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
