Q:

How far can a bullet travel underwater?

A:

Quick Answer

According to MythBusters, bullets from high-powered guns disintegrate in less than 3 feet underwater. Slower bullets, including those from pistols, travel for about 8 feet underwater. Bullets fired at an angle stop underwater at shorter ranges than those fired vertically into water.

Full Answer

Water is denser than air, making it more difficult for objects to move. Forces that result in forward movement are known as thrust. Drag slows movement by pulling against thrust. When thrust is greater than drag, forward movement results. In water, drag is greater than in air, resulting in more difficulty with forward movement. The movement of currents in water also affects the ability of objects and animals to move underwater.

    What is the terminal velocity of a bullet?

    A:

    Terminal velocities of bullets vary by caliber, but can reach 300 to 700 feet per second. For example, a .30 caliber bullet's terminal velocity is 300 feet per second. If the bullet is shot at an angle and keeps its arc, it is more likely to reach terminal velocity.

    How do bullet trains work?

    A:

    Bullet trains, also called maglev trains, operate with magnetic levitation technology developed by Japanese and German engineers. Japanese engineers refer to their method as electrodynamic suspension while German engineers refer to their method as electromagnetic suspension. Either way, magnets raise the trains above the track, which means there is no need for wheels.

    How fast can maglev trains travel?

    A:

    Maglev trains can reach speeds of up to 361 mph. This was the fastest speed reached by the MLX01, which was measured on December 2, 2003. Executed on the Yamanashi maglev test line in Japan, the test run was administered by the Central Japan Railway Company and the Railway Technical Research Institute.

  • Q:

    How does sound travel?

    A:

    Sound travels in waves from a transmitter to a receiver through a medium. The wave is produced by the vibration of particles in mediums such as gases, liquids and solids. Because sound requires a medium of interconnected and interactive particles, it cannot travel in a vacuum such as space.
