A transverse periodic wave on a string with a linear density of 0.200 kg/m is described by the following equation: y = 0.005 sin(419t ? 21.0x), where x and y are in meters and t is in seconds. What is the tension in the string?

the increase in internal energy of 1 kg of water att 100dgree celsius when it is converted into steam at same temperature and at 1 atm (100kpa ) will be (the density of water and steam are 1000kg/m^3 & 0.6kg/m^3 respectively) .the latent heat of vapourisation of water is 2.25 x10^6j/kg)



the internal energy of a monoatomic ideal gas is 1.5nRT.1 mole of helium is kept in a cylinder of cross section 8.5 cm^2.he cylinder is closed by a light frictionless piston .he gas is heated slowly in a process during which total of 42 J heat the is given to the gas.if temperature rises through 2 dgree celsius,the distance moved by the piston is (atmospheric pressure being 100kpa)



consider a classroom that is roughly 5m x 10m x 3m. initially at=20 degree celsius and p= 1atm .there are 50 people in an insulated class losing energy to the room at the average rate of 150 watt per person .how long can hey remain in class if the body temperature is 37 degree celsius and person feels uncomfortable above this temperature.heat capacity of air =(7/2 R).
