Two humid air streams are adiabatically mixed at 1 atm pressure to form a third stream. the first stream has a temperature of 40°c, a relative humidity of 40 percent, and a volumetric flow rate of 3 l/s, while the second stream has a temperature of 15°c, a relative humidity of 80 percent, and a volumetric flow rate of 1 l/s. calculate the third stream’s temperature and relative humidity.

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong chain

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
