A uniform rod of mass 3.05×10?2kg and length 0.350m rotates in a horizontal plane about a fixed axis through its center, What is the angular speed of the rod after the rings leave it
NaOH(aq) is rapidly mixed with an equal volume of 0.020 mol L^-1 HCN(aq). Calculate the time, in seconds, required for this [OH] to decrease to 1.0×10^4 mol L^1. (Hint: Start from the rate law in the form Rate = k [HCN ]^n[OH]^m.
Compute the DFT of the first 4096 points of the noise and plot the noise's DFT magnitude in dB vs. frequency. Notice that the noise DFT magnitude is "flat" (well, it is quite ragged, but the top of the plot is flat), which is why this kind of nois
A study is conducted to determine if time of day has any effect on test grades. An introductory psychology class is selected for the study, because it has a standard curriculum taught across many sections. Two classes are selected for each time perio
