1. What is the difference between longitudinal and transverse waves? Compare and contrast the direction of their movement, movement of a molecule
through the completion of a cycle, and amplitude and wavelength
measurements of each type of wave.
2. Suppose that a wave has a period of 0.03 second. What's its frequency? Be
sure to show the steps for your work.
3. Compare a wave that has a period of 0.03 second with a second wave that
has a period of 1/4 second. Which wave has the greater frequency? Be sure to
show the steps for your work.
4. If a wave has a wavelength of 4.5 meters and a period of 0.007 second, what's
the velocity of the wave? Be sure to show the steps of your work.
5. Using the image below, identify the numbered parts of the wave.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

idk what is it? is this a question that you know the answer or u dont

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
