Driven RC circuit in parallel. A capacitor C is connected in parallel to a resistor R and an AC source providing a voltage v(t) = V sin(ωt).

(a) Make a phasor diagram at time t showing all relevant based on Kirchhoff’s rules.

(b) Find the impedance of this circuit and make a plot of Z vs. ω.

(c) What are the small and large frequency behaviors of the peak capacitor and resistor currents?

(d) What is the phase difference between the total current and the input voltage? (e) (5pts.) Write an expression for i(t), the total current thought the circuit, if V = 120 V, C = 47 µF, R = 230 Ω, and f = 440 Hz

My physics class is working on Ohm's law and we did a lab about series and parallel circuits. While doing the lab report I got stuck on this question below. Please help!

"What contributed to the percentage difference? In other words, account for sources of errors."

This is my data:

An experiment is given together with an event. Find the (modeled) probability of each event, assuming that the coins are distinguishable and fair, and that what is observed are the faces uppermost.

Three coins are tossed; the result is at most one tail.

Was Stanley Milgram’s Study of Obedience Unethical?

I believe Milligram's study of obedience was unethical. Not only was it deceptive, the participants were pressured to continue and many of the teachers were under a great deal of stress because of it. I know that the experiment was on obedience but the BPS states that researchers are responsible to fully inform participants of their right to withdraw from the experiment at any time. The participants were allowed to withdraw, but they were under a great deal of pressure to continue even when they didn't want to. Deception is lying, and it is always better to be truthful. Lies are lies no matter what the intention, and they are still wrong. My biggest reasoning, however, is the stress the experiment caused on those participants. They had no idea they that there was not any harm coming to the person they were shocking. "Many of the participants were visibly stressed. Signs of tension included trembling, sweating, stuttering, laughing nervously, biting lips and digging fingernails into palms of hands. Three participants had uncontrollable seizures, and many pleaded to be allowed to stop the experiment." (McLeod, S.A., 2007. www.simplypsychology.org/miligram.html) Miligram claimed that afterwards the majority were glad they had participated in the experiment, but there was still too much stress on them. If one of them had unknowingly had heart issues they could have had a stroke or heart attack from the strain. This is why I believe his study was unethical.

Experiment 4

Dr. Brown wanted to observe the effects of music genre on surgical recovery time. Dr. Brown set up an experiment in which participants were randomly assigned to listen to one of three different genres of music (rap, metal, or country). Participants were patients who had just received liposuction; they listened to their assigned music genre for 2 hours each day until discharged from the hospital. Dr. Brown recorded the number of days the patients remained in the hospital. His results are shown below.

Using the data shown below, conduct the appropriate statistical test in SPSS to determine whether there is a statistically significant difference between any of the pairs of musical genres.

1. What is the design of this experiment?

Three-way between-subjects factorial design

Three-way within-subjects factorial design

One-way between-subjects factorial design

One-way within-subjects factorial design

2. What kinds of samples are being used in this experiment?

Independent samples

Dependent samples

Matched samples

3. In the blank space in the conclusion below, write the statistical results of the experiment you analyzed above in APA style:

Based on the results of a one-way ANOVA, music genre does have an effect on number of days to recover from surgery,_________.

i wish to solve the equations v'=v^3/3-w+i, w'=g(v+a-bw) with a=0.8, b=0.7, g=0.08, i=0.5 using ode45 in matlab. i solved in on paper but i don't know how to type the codes in matlab.

i googled this but for one unfamiliar with the code, it is hard to fathom what they are solving i also would like the code to show the plots of both variables changing with time and the phase plots of both variables.

The Kaufman car company sells cars with a warranty that they will work properly. based on its historic experience, it expects the cost of honoring this warranty to be about 1% of sales. In 2014, it makes $500 million of sales. Assume all the warranties for these cars expire at the end of 2016. The actual costs to fix the cars was $1,700,000 in 2014, $2,000,000 in 2015, and $1,200,000 in 2016. What expense would the company record:

A. In 2014, as it sells the cars?

B. In 2014, as it pays the $1,700,000 in claims?

C. In 2015, as it pays the $2,000,000 in claims?

D. In 2016, as it pays the $1,200,000 in claims?

E. At the end of 2016, when the warranties expire?
