If water at the top of the falls is at 16.4°C, what is the maximum temperature of the water at the bottom of the falls? Assume all the kinetic energy of the water as it reaches the bottom goes into raising the water's temperature.
In many ways, comparing multiple sample means is simply an extension of what we covered last week. Just as we had 3 versions of the t-test (1 sample, 2 sample (with and without equal variance), and paired;
Would you xpect the α-protons of a thioester to have a lower or higher pKa than an ester? Why? Remember the pKa values for the α-protons of several FG's: aldehyde(17), ketone(21), ester(25), amide(35).
You have three 3.0 uF capacitors. Two of the capacitors are in parallel, and this parallel combination is in series with the third capacitor. This capacitor combination is connected across a 30-V battery. Find the charge on each capacitor and the
