Ahammer taps on the end of a 3.8-m-long metal bar at room temperature. a microphone at the other end of the bar picks up two pulses of sound, one that travels through the metal and one that travels through the air. the pulses are separated in time by 8.80 ms . what is the speed of sound in this metal?

the speed of sound in this metal is 1668 m/s

Explanation:

given information:

x = 3.8 m

t = 8.80 ms = 0.0088 s

the speed of sound in the metal

v = x/Δt

to find the Δt of the metal, we have to calculate the interval time sound in the air

= x/, = 343 m/s

so,

 = 3.8/343 = 0.01108 s

Δt =  - t

    = 0.011079 - 0.0088

    = 0.002279

v = x/Δt

  = 3.8/ 0.002279

  = 1668 m/s

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
