W 9 Form Pa: Fill & Download for Free

HelloSo with isothermal PV =P'V'Isobaric PV=P'V' and P=P'Adiabatic PV^y = P'V'^y with y=1.4So take V=3 m^3 and V'=9 m^3 and P = 9 PaSo the formula W = P*ΔV if we integrate this for the above examples we get.Isothermal: W= 3.30 JIsobaric: W= 6 JAdiabatic: W= 2.67 JSo W2>W1>W3This is a quick answer. But I hope it helped. Otherwise you can comment your questions.

A2AI live in San Francisco, California, in the 12th Congressional District (Nancy Pelosi’s). In the Castro. This is arguably the most reliable Democratic constituency in the US. In my precinct of 500 or so voters, a grand total of five (5) people voted for Donald Trump.Thus, I had (and have) the luxury of knowing that my vote has pretty close to zero chance of having an impact on the election, so I get to vote as I want and do not have to vote “strategically.” So the person I vote for (not Donald Trump, in case you’re wondering) is certainly not going to win.At the current place and time (4th of June), I honestly do not see a path to victory for the president; I think he is going to lose, and it is not going to be close.How surprised/shocked would I be if Trump were to win?I would be far more shocked than I was in 2016.I was mildly surprised that he was able to win in 2016, but not stunned. I’ve been asked many times about the election, why the polls were “wrong” (TL/DR: they weren’t), and how the outcome occurred. It basically came down to three states (PA, MI, and WI) whose pivotal counties all went one way and not the other.The arithmetic and the path to 270 were obvious, if unlikely. Trump had the equivalent of an inside straight, and he drew the cards he needed.In 2020, the path for Trump is much more difficult than it was in 2016.If you look at the map (this one reproduced from the New York Times):and use it as a starting point for 2020, the questions are four-fold:Which states that Hillary Clinton won are possible Trump targets?New Hampshire was the closest state that Clinton won, and she won by about 3,000 votes. That is likely his best chance to pick up a state.Nevada is next. In this state, Clinton edged out Trump by just under 30,000 votes (out of a million total cast). That is his second best target.After that, it gets much more difficult - Virginia was won by Mrs Clinton by over 200,000 votes (total votes about 3.7 million).NH is four electoral votes. Nevada is six. Virginia is 13. So the state EV totals go down as the sizes get larger.Trump right now is under water in all of those states. Significantly in some cases. In NH, Trump trailed Biden by 8% in the most recent poll[1], by 4% in Nevada[2], and by 12% in Virginia[3].The likelihood that Trump is going to pick up any states he lost in 2016 is pretty slim, and the ones he has any chance to capture are small. So Trump basically is 100 per cent on defence.So how does that look? Looking back on his inside straight (WI, MI, PA), he can afford to lose two of them, but not all three (presuming he defends every other state that he won in 2016). He is behind in all three. PA (the “Keystone State”) is the linchpin of his path. He is consistently trailing there[4] in polls. It’s a similar story in Michigan [5]and Wisconsin[6].The same dynamic I think applies in 2020 as in 2016 - that is to say, if there is some endogenous variable that tips PA to Trump, it will likely also affect voting in MI and WI to some degree.But the reverse is also true. If some factor tips PA towards Biden, it almost surely will tip MI and WI to the blue column.And this says nothing about other large states - Florida in particular, but also North Carolina and to a degree, Ohio as well. Florida is a state with a lot of senior citizens. No group has been affected by the failure to control SARS-CoV-2 than the elderly, and for better or for worse, the president is the face of the failure to respond rapidly and effectively. Trump is in serious danger of losing Florida.And the scandal in North Carolina - where Republican Senator Richard Burr was caught advising people to dump stock just prior to the explosion of COVID-19[7] - has a real possibility of further poisoning the Republican brand. Right now, North Carolina polls are close, but they tip to the former VP[8]. Florida[9] is very similar - with Biden now with sustained and consistent leads on Trump.These are big states. If Trump loses Florida (29 EVs) and/or North Carolina (15), he is going to take on more water than he likely can survive. And again, losing one or both would indicate that the underlying factors tilt to Biden.I don’t see an election where Trump loses, say, Florida, but wins in any of the swing states (PA, WI, MI) that he won in 2016.Events are not in his favour. Four months ago, the stock market was at record highs, unemployment at record lows. Income growth statistically was real and at its best point in decades. Consumer confidence was high, and Trump was crowing daily.This is no longer the case. The optics of over 100,000 (and climbing) dead from COVID-19 played out over his earlier comments that it would “go away” or that “15 is headed to zero quickly” are going to be replayed ad nauseum. The markets crashed, wiping out trillions of dollars. Shelter in place orders landed in most states.And then there is this very easy to understand chart:This was before the taped killing by police of George Floyd and a week of protesting and violent unrest. Trump’s handling has been (IMHO) terrible. Communicating via Twitter about sending in the army in an attempt to look like a tough, law and order president contrasted dramatically with the optics of a man hiding in the White House surrounded by soldiers projected just the opposite - weakness. He looked like a tin-pot head of state under siege.His handling of the situation could scarcely have been worse. It showed no empathy for the man killed, no understanding for why the protesters were in the streets, and even from a law and order perspective, showed weakness and indecision. His actions pleased pretty much no-one, and have rightly drawn criticism.I haven’t seen polling data yet as to how the protests have impacted the president, but I would be shocked if they helped him.There are two websites I read most days for a temperature check.One is electoral-vote.com[10][10][10][10], which is run by a couple of left-of-centre webmasters. The comments are heavily Democratic, but the data are very useful. As of today, based on the polls, they project that Biden is leading in the EV race by 353–185. Their map includes ALL of the Trump-friendly Democratic states, and also Ohio, Florida, North Carolina, and even Georgia. They do not appear to use weighted moving averages, so the map is I think unlikely to be that unfriendly to Trump, but it puts him in a very tough spot.The second is predictit.org[11][11][11][11], which is a betting forum where the payouts reflect the current mood in a way similar to the payouts at the track - the more people betting on a “horse,” the lower the payoff and vice versa. This in a way reflects the “wisdom of crowds,” as people are unlikely to make a big bet on a contestant likely to lose.Right now, the bets favour Biden to win 334–204. Biden is projected to pick up the Trump Three, plus Florida, North Carolina, and Arizona. Over-all, the bettors favour Biden by 55–45. This is a steep reversal - on March 3, Trump led Biden by 53–44[12][12][12][12]There remain five months in the campaign. Biden has yet to be put to the test on the trail, where he is certainly capable of torpedoing his own chances. Some event could come along and give Trump a softball opportunity to look “presidential” (honestly, the killing of George Floyd should have been a lay-up for the president, but he missed it, badly).But right now, the president’s chances are poor and sinking daily. Absent the ‘meteor in the sky’ event, I would be shocked if he won in November. VERY shocked.Footnotes[1] New Hampshire Polls[2] Nevada President: general election Polls[3] Virginia President: general election Polls[4] RealClearPolitics - Election 2020 - Pennsylvania: Trump vs. Biden[5] RealClearPolitics - Election 2020 - Michigan: Trump vs. Biden[6] RealClearPolitics - Election 2020 - Wisconsin: Trump vs. Biden[7] Sen.

You can do this!I hope this helps!(This took a lot of time so an upvote will be appreciated :) )Cheers!Edit:Thanks to Anindya Mahajan & Gadangi Nitish for pointing out the mistake in my answer to Maths Question 16.
