Some hydrogen gas is enclosed within a chamber being held at 200 degrees C with a volume of 0.025 m^3. The chamber is fitted with a movable piston. Initially, the pressure in the gas is 1.5*10^6 Pa (14.8 atm). The piston is slowly extracted until the pressure in the gas falls to .95*10^6 Pa. What is the final volume of the container? Assume that no gas escapes and that the temperature remains at 200 degrees C.
A firefighter at a distance d from a burning building directs a stream of water from a fire hose at angle θi above the horizontal as shown in Figure. If the initial speed of the stream is vi. At what height h does the water strike the building?
A parallel beam of light from a He-Ne laser, with wavelength of 644 nm, falls on two very narrow slits 0.05 mm apart. How far apart are the fringes in the center of the pattern on a screen 2.2m away.
Two particles of charge Q(-L,0) and nQ(αL,0) where n = 10. When a third charge is placed at the origin, it is found that the force on it is zero. Find out α.

At a grinding wheel has an angular velocity of 27. It has a constant angular acceleration of 26.0 until a circuit breaker trips at time = 1.60 . From then on, it turns through an angle 433 as it coasts to a stop at constant angular acceleration.
A thin soap film (n = 1.302) suspended in air has a uniform thickness. When white light strikes the film at normal incidence, violet light (&lambdav = 412 nm) is constructively reflected. At what angle of incidence will green light (&lambdag = 562..
