An ideal gas is taken from an initial state "i" to a final state "f" in such a way that the ratio pressure to the absolute temperature remains constant.What will be the work don by gas?
The pressure of a gas changes linearli withe volume from 10kpa,200cc to 50kpa,50cc.
1)Calculate work done by gas
2)If no heat heat is supplied or extracred form gas,what is change in internal energy of gas?
f(x)=((x4-3x2+x+7/x4-2x2+1)-1)1/2
A uniform horizontal rod of length 40cm and mass 1.2kg is supported by two identical wires as shown.Whear should mass of 4.8kg be placed on road so that the same tuning fork may excite the wire on left into its original vibration and that on right first ovetone?
A heavy ball is suspended from the celling of a moter car through a light string.A transvers pulse travels at aspeed of 60cm/s on the string when car is in rest and 62cm/s when the car accelerates on a horizontal road.Find the acceleration of the car.g=10m/s2
Two waves travelling in the same direction through the same region ,have equal frequecies wavelengths and amplitude. if the amplitude of each wave is 4mm and the phase differance between the wave is 900,what is the resultant amplitude?
The equation of a standing wave produced on a string fixed at both ends is
y=(0.4cm)sin((0.314cm)x)cos((600s^-1)t)
What could be the smallest lenth of the string?
can any one give answear of questions 31 to33 from H.C.verma from chapter wave motion
