Hisham Tawfiq has an estimated net worth of $200,000. He plays Dembe Zuma on the show. Dembe is Redâs sidekick, security detail, and bodyguard. Dembe has always got Redâs back, scaring off any would-be assassins at every turn. Heâs been on the show since 2014 and frankly Red would probably be dead without him.
The speed of sound in a material, particularly in a gas or liquid, varies with temperature because a change in temperature affects the material's density. In air, for example, the speed of sound increases with an increase in temperature.At 32 Â°F. (0 Â°C.), the speed of sound in air is 1,087 feet per second (331 m/s); at 68 Â°F. (20 Â°C.), it is 1,127 feet per second (343 m/s).The terms subsonic and supersonic refer to the speed of an object, such as an airplane, in relation to the speed of sound in the surrounding air.he speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
Use the interactive Speed of Sound calculator below to see the effect of temperature on sound's velocity. For comparison, the speed of light in a vacuum is 299,792,458 meters per second or 186,000 miles per second (669,600,000 mph), which is roughly 870,000 times faster than the speed of sound.
