the velocity of the sound will be double of its velocity at 27degree Celsius when temperature is?

wrong jattiman,\nv is not proportional to temperature\nv2 is proportional to absolute temp\n\nvelocity doubles at 1200 kelvin = 927 deg C

Let f1 = 35.0 kHz\nvbat = 12 m/s\nvsound = 330 m/s\n\na) f2  = vsound*f1/(vsound-vbat) = 330*35/(330-12) = 36.32kHz\n\nb) For bat f = (vsound+vbat)*f2/vsound = 342*36.32/330 = 37.64kHz\n\nc) It will obviously affect the answers

First find Vo:  Vo^2 = Rg/sin(28)  Where R = range & 8 = theta\n\nUsing your numbers, Vo = 41.523 m/s\n\nImpulse = change in momentum ----> Ft = mVo---> F = mVo/t\n\nSo, F = (.0431kg*41.523m/s)/.00438sec = 408.59 N\n\nVoila!

pV = n R T => if pressure is constant => p = n R T / V = const. => p / n R = T/ V = const.\n=> T / V = const.\nT1 = 333 K\nT2 = 533 K\nV1 = 0.2 m3\n\nT1 / V1 = T2 / V2 =>\nV2 = V1 x T2 / V2 = 0.2 x 533 / 333 = 0.32 m^3\nanswer D is correct

Depends on pressure/altitude.  At sea level its about 100C or 212F.

V1T2 = V2T1\n147mL * (57+273K) = V2 * (28 + 273K)\nV2 = (147mL * 330K)/ 301K\nV2 = 161mL\n\nTherefore, volume at 57C is 161mL. Its logical since when temperature rises, volume increases.

It depends what degrees you're talking about. For example, if it were 0 degrees in Celsius, that's 32 degrees Farenheit, and twice as cold would logically be 16 degrees Farenheit. But 0 degrees Celsius is also 273 degrees Kelvin, and twice as cold would be 136.5 degrees Kelvin. I guess in this case, the units of measure really matter.

The volume will be 549.5 mL.  Let me know if you want to see the work.   Use this equation PV/T=P*V*/T*.    P,V, and T are just the pressure, volume, and temperature for the initial system (they are usually represented as P1,V1, and T1 but I left out the numbers which should be subscripts for simpliofication because yahoo does not have many text options.)  P*,V*, AND T* are the pressure, volume, and temperature after the system has been changed.  You could use any units pretty much for the pressure and volume as long as you keep the units consistent.  However always use Kelvin for the temperature.  Kelvin = 273 + Celcius Temp.

v=vo + at\nv=0 + (9.8)(8)\nv=78.4\n\ny=1/2(vo + v)t\ny=1/2(78.4)(8)\ny=1/2(627.2)\ny=313.6m\n\nB

Ok-i'm not quite sure if i did this right--we covered this last year--so you might want to double check with your textbook or teacher, or whatever resource you have...\n\nwhat i would do is find the final temperature:\nFinal Temperature=(V2 * T1) / V1\n\nand then use the delta T, delta v, and P to find delta E.\n\nbut i'm really not that sure.\n\nsorry that i wasnt a better help!

A.\nhalf the pressure = double the volume. \ntriple the temp = triple the volume.\ntriple x double = 6 times the volume.

First of all, 3 x 10^8 m/s is the speed of light in a vacuum. Thanks for nothing there.\n\nNow, for the speed of sound ...\n\nThe typically cited value is about 340 m/s in standard atmosphere, but the actual speed of sound varies with the medium. \n\nFor an ideal gas, the speed of sound is defined as follows:\n\na = SQRT(gamma*R*T), where gamma is the ratio of the heat capacities of the gas, R is the universal gas constant, and T is the absolute gas temperature. Similar correlations exist for the speed of sound in solids and liquids which depend on the density and thermophysical properties of the medium.

The 'speed of sound (from Latin celeritas, "velocity") varies depending on the medium through which the sound waves pass. It is usually quoted in describing properties of substances (e.g. see the article on sodium). In conventional use and in scientific literature sound velocity v is the same as sound speed c. Sound velocity c or velocity of sound should not be confused with sound particle velocity v, which is the velocity of the individual particles. More commonly the term refers to the speed of sound in air. The speed varies depending on atmospheric conditions; the most important factor is the temperature. The humidity has very little effect on the speed of sound, while the air pressure has an effect (see equations later in the page). Sound travels slower with an increased altitude (elevation if you are on solid earth), primarily as a result of temperature and humidity changes.
