In a diagnostic X-ray procedure, 4.48×1010 photons are absorbed by tissue with a mass of 0.640 kg. The X-ray wavelength is 0.0150 nm. What is the total energy absorbed by the tissue?

I'm not sure how to go about this, any help would be greatly appreciated!

Thanks!

I had been on paxil for 11 years and recently stopped taking it, but I still have some from when I was. This morning by boyfriend went to take an Advil because he had a headache and by mistake took two 10mg paxil instead (it was still dark out). He says he feels fine just tired and cannot concentrate, he has slept most of the day. I know that 20mg is not a high dose but could it harm him since he has never taken it before, or is he actually just really tired?

Ok I will try and make a long story short, on monday (it is now thursday) i went to the doctor with extreme pain in my lower back, he gave me muscle relaxers. That night I had blood in my urine and it burned when I urinated. The next day the pain had not stopped and it now was in my side. I went to the hospital, and they said I had a severe UTI or kidney infection. They gave me antibiotics and pain killers. The doctor said the pain should start getting better in 12 hours. After 48 hours on meds I went back to the hospital as my doctor wanted to see if it was my appendix. They did another urine test and did blood work. The pain is now starting in my back on the other side? The doctors said my white blood cells and everything is fine... so long story short has anyone had a kidney infection, and when can I expect this pain to go away?

Thanks

So he likes action/ war boy movies and I like romantic comedies and chick flicks. I don't think I have ever finished a movie he picks out, I either fall asleep or get so bored I do something else. He will watch movies that I pick but it is so obvious he hates it lol. We both liked Sherlock Holmes and we can agree on something stupid like 40 year old virgin and that's about it. Any suggestions out there would be appreciated something that meets in the middle?

Thanks

I am going on a Christmas cruise with my boyfriend (of 2 and a half years) and his family and I don't know what to take with me that I can give to his parents on Christmas! Both of them are doctors and they are very very well off so they don`t really `need` anything. I just want to give them something to say thanks for everything they do for me and give me. If I was home I would give them a nice bottle of wine or something (they love their wine) but I can`t take alcohol on the cruise ship with me!

So help me out, something nice, that is small enough to put in my suitcase, and that i am obviously allowed to fly with and take on the boat?

Oh and P.S I am university student trying to pay my way through school so nothing to crazy and expensive

Two spreadsheet programs (A and B) are compared to see which is easier to use. The study in problem 6 was repeated in the Faculty of Science. Samples of size 10 and 15 were used for program A and program B. In this case the mean time for the students using program A was 52 minutes, and the mean time for students using program B was 42 minutes. The pooled standard deviation Sp was equal to 9 minutes. Using this faculty of Science data, test the alternative hypothesis that the mean time for program B is less than the mean time for program A.

a) What is the value of the test statistic?

b) How many degrees of freedom does the test statistic have under the null hypothesis?

c) What is the p-value for the test?

d) Find a 95% confidence interval for the difference in population mean completion times between Program A and Program B.

ANY HELP WOULD BE GREATLY APPRECIATED :D THANKS SO MUCH!

I have been on paxil since I was 9 years old(I know stupid doctor!), I am now 20. For the past 3 years or so I have been trying to get off it but I always get soo bad (nausea, depression, headaches, dizziness, mental breakdowns etc.) that they put me back on. I have been very very slowly weaning myself off, about 3 months ago I went from 15mg to 10mg and i am still suffering withdraw symptoms. I really really want to get off this drug, i have no sexual drive whatsoever and my worse nightmare is getting pregnant (which I don't plan on happening but still..) at some point and still being on this drug!

Is their anyone out there who has come completely clean of this drug, did you get these awful withdraw symptoms, please some advice how did you do it???

I am 20 years old and going out to a bar on halloween with some friends, do you think this costume is too slutty?

I was diagnosed with strep throat on Monday, I got it on Saturday. I have been on antobotics since moday and am finishing my prescription today. My throat is still a little sore but nothing compared to how bad it was and all my other symptoms are gone! So my question is am I still contagious? I am going to see my boyfriend tonight, he has been away for two weeks, I am so excited to see him but I don't want to get him sick!

My best friend whom I have known forever and my boyfriend are not only both Aquarius, they share the same birthday. They were both born on February 18th of the same year. Is this just a coincidence or are Geminis and Aquarius a good match? I have always found it odd, maybe I just have a thing for Feb 18th haha

What do you think?

My boyfriend bought tickets for me and him to go to a concert, in the past he has always paid for me when we go to the movies etc, however I feel bad because I am completley capable to pay for myself. How do I offer to pay without making him feel like less of a man.
