Work done by a gas an ideal diatomic gas, for which the specific heat capacites (i. e. per mole) are cy = 5r/2 and cp = 7r/2, occupies a volume of 2m at a pressure of 4 atm and a temperature of 20°c. the gas is compressed to a final pressure of 8 atm. compute the final volume, the final tem- perature, the work done by the gas, the heat released, and the change in internal energy for: (a) a reversible isothermal compression. (b) a reversible adiabatic compression. hint: prove that pv" where 7 = cp/cu for an adiabatic process.

need to see circuit to get time constant

the total distance traveled by the car is

30km + 49km = 79 km .

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
