Steam burns are pretty dangerous because there's often a lot of thermal energy in the steam. When the steam hits you, it is going to

transfer some of that energy to you, cooling the steam. If a 6.4 kg cloud of

steam at 150 degrees, hits you and cools to 100 degrees, What is the loss

of heat energy? (no scientific notation)

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
