by frictional heating, when an object travels hypersonically through the atmosphere. Since a plasma’s particles are electrically charged (the electrons negatively and the ions positively), their
【3】Aerodynamics manipulates gases. Magnetohydrodynamics manipulates plasmas. These are gas-like fluids whose atoms have been ionised by losing some or all of theirelectrons—as happens to the air, byfrictionalheating, when an object travels hypersonically through theatmosphere. Since aplasma’spartic...
sound travels in waves through a medium, such as air or water, by causing particles in the medium to vibrate. the vibrations create changes in pressure that propagate as sound waves, eventually reaching your ears for interpretation. can sound be converted into digital signals? yes, sound can ...
When you hear an alarm clock ringing, you're listening to energy making a journey. It sets off from somewhere inside the clock, travels through the air, and arrives some time later in your ears. It's a little bit like waves traveling over the sea: they start out from a place where ...
east to west is the direction in which the air molecules move when the sound wave travels from east to west. q5 what is the product of the time period and frequency of a wave? the product of the time period and frequency of a wave is unity. q6 what happens to the frequency of a ...
Waves occur when there's a disturbance in a system, and that disturbance travels from one place to another. There are two main kinds of waves: mechanical waves and electromagnetic waves. The main difference is that mechanical waves need a medium to travel (a material), whereas electromagnetic ...
For example, when the head of a drum is hit with a mallet, the drumhead vibrates and produces sound waves. The vibrating drumhead produces sound waves because it moves alternately outward and inward, pushing against, then moving away from, the air next to it. The air particles that ...
while the speed of sound in steel is equal to 5100 metres per second. another interesting fact about the speed of sound is that sound travels 35 times faster in diamonds than in the air. speed of sound in liquid similarly, the density of a liquid is greater than the density of a gas....
travels. Sound travels its slowest through air at about 343 meters per second, or 1 kilometer in ~2.9 seconds. Thespeed of soundincreases with increased density, because the particles of matter are closer together and therefore can influence each other more quickly when displaced by a sound ...
surrounding natural magnet. This causes the electromagnet to move back and forth. As the electromagnet moves, it pushes and pulls aspeaker cone, which rapidly pushes out air and then pulls back in. This movement of air particles produces the sounds wehear. (For more information, seeHow ...
