Using the tables for water, determine the specified property data at the indicated states. (a) at p = 3 bar, v = 0.5 m3/kg, find t in °c and u in kj/kg. (b) at t = 320°c, v = 0.03 m3/kg, find p in mpa and u in kj/kg.(c) at p = 28 mpa, t = 700°c, find v in m3/kg and h in kj/kg. (d) at t = 10°c, v = 10 m3/kg, find p in kpa and h in kj/kg.

Scientists use laser range-finding to measure the distance to the moon with great accuracy. a brief laser pulse is fired at the moon, then the time interval is measured until the "echo" is seen by a telescope. a laser beam spreads out as it travels because it diffracts through a circular exit as it leaves the laser. in order for the reflected light to be bright enough to detect, the laser spot on the moon must be no more than 1.0 km in diameter. staying within this diameter is accomplished by using a special large-diameter laser. part a if λ = 540nm , what is the minimum diameter of the circular opening from which the laser beam emerges? the earth-moon distance is 384,000 km. express your answer to two significant figures and include the appropriate units.

Which type of basaltic lava flow has a fairly smooth

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
