Why is a gearbox required?
It allows a greater range of speeds, increase performance and fuel economy.
How fast does bobsled travel?
A bobsled can reach speeds between 80-90 miles per hour (130-145 km/h) on a standard track, while the top speeds can exceed 90 miles per hour (145 km/h) on larger tracks.
Why do turbojets increase efficiency at high speeds?
Turbojets increase efficiency at high speeds because they rely on the forward motion of the aircraft to compress incoming air, which reduces the amount of work the engine has to do compared to slower speeds. This allows turbojets to produce more thrust for the same amount of fuel, resulting in improved efficiency at higher speeds.
Why does a car move towards a truck when it speeds past?
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds
Why do you thik the winds speeds on the gas giants are so mush greater that the wind speeds on earth?
Their cores are spinning faster.
What is the purpose of making the train float above the rails when it is moving forward?
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.

What allows for the transfer of large amounts of data at high speeds?
broadband
What is the use of flaps in airplanes?
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.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
Is there any insect or bird that flies at speeds greater than sound?
Concorde
Who invented a sail for maneuvering and maintaining greater speeds?
jorge e. klenton
