3. A psychologist wants to determine the effect of instructions on the time required to solve a mechanical puzzle. Each of 20 volunteers is given the same mechanical puzzle to be solved as rapidly as possible. Before the task, the subjects are randomly assigned in equal numbers to receive two different sets of instructions. One group is told that their task is difficult (M1), and the other group is told that their task is easy (M2). The score for each...

1. If I=35,000 time the threshold of hearing, what is the difference in db? 2. Mathematically prove that the threshold of pain is 130db. (Mathematically prove means to show an equation and solution) 3. If one speaker is quieter than another, what is the reduction in db? a. If it has only 1/3 the intensity of the other? b. If it has only 1/6 the intensity of the other? 4. Mathematically prove that a 10db increase is 10 times the...

A.) In the lab, you will determine a value for the time constant of the RC circuit, by measuring the amount of time it takes the capacitor voltage to increase from 0.0 V to ______ % of its maximum value. B.) If you only have capacitors of one value, you can change the total capacitance of the circuit by using combinations of capacitors. Assuming that all the capacitors have the same value, how could you increase the total capacitance? Options:...
