Physics momentum/impulse help?
I have a physics problem that gives me the initial and final velocities of a .30 kg baseball.
The answer is given with iHat and jHat and I thought it would come out as a number. Even when I break down the answer I get into parts, it still isn't right. How do I do this problem? Thanks in advance for your help :)
1 AnswerPhysics7 years agoHow small is too small for a pinhole camera?
Is .2 mm with a focal length of 20mm too small? I'm afraid not enough light is getting in. I'm still waiting to get film back from being developed. I thought I'd ask so I know what to expect. Thanks :)
3 AnswersPhotography7 years agoI just made a pinhole camera...and...?
Before I put the film in I checked to see if an image is being projected on the back part, and I was having a tough time seeing anything. I could only see bright lights or the sun projected. I'm worried that the film isn't going to pick up on anything. It's about f/106. Focal length is 20mm and the pinhole is a fraction of a millimeter (close to .02mm). The practice film I used is 400 iso, but i'm going to put 200 iso if the 400 gets an image. I'll find out soon enough, but I was wondering what anyone thought about this. Do you think it'll make an image? Is there enough light?
OH and how much longer do you think exposures should be with 200 iso compared to 400? Thank you very much!
4 AnswersPhotography7 years agowhy can't pinhole cameras take pictures of the milky way? What is the minimum requirement to do that?
I know pinhole cameras can't gather that much light. Is that the only reason? What if you made a simple camera with a small lens with an f/ of about 2.25 and 3200 ISO film? or would that not work? I'm curious because I haven't seen any old photos of the milky way when all they had were simple cameras.
thanks for your help.
5 AnswersPhotography7 years agoJeep cherokee steering wheel locked. What's causing it?
Today when I turned on my car and started backing up, there was a loud snapping noise and my car started to shake. As I backed up and drove forward it shook and I thought maybe a tire was flat or something, so I checked, and they were fine. When I went to turn my car on again, it had a hard time starting, but when it did start, it shook and made a loud rattling noise. As I was driving home it kept making the noise and eventually the steering wheel was hard to turn. I put more power steering fluid in case it was that, but it still hasn't unlocked. It's nearly impossible to turn. What could be causing this?
Also, the car seemed to be overheating on the way back, too.
Thanks for your help!
1 AnswerJeep8 years agoMonologue to choose...?
I am going to audition for a short film and I am not sure where to get my dramatic monologue from. The part is for a struggling musician. I assume that I should prepare something that will be similar to what the film is about, but I'm not really sure because I've never done this before. Where should I get the monologue from? Movies? Any suggestions or even tips on how to deliver it would be great. Thank you very much!

I'm just wondering if anyone has ever gone to them and if you have, how many people were there? Was it really crowded? And how long were you there? Is it different if you arrive early at the 7am audition than if you go to the 2pm audition? Thank you!
1 AnswerSinging9 years agoWhere can I find Sheet free music for "Trouble Man" by Marvin Gaye?
I can't find any kind of tutorial on youtube, or at least any chords... Where can I find the sheet music? Can you find it? if you do, can you please answer with a link? I've tried as many of those "free sheet music" sites as I could find. I don't want to buy it because I just need a few of the first chords to figure it out.
Thank you in advance!

i went to a salon in west hollywood to get my hair done and they used something on my hair and now it is way healthier than it used to be. I was shocked.
I wanted to know what it was he put in my hair. He washed my hair and put the stuff in. He left it in and sat me under the hair dryer thing for a few minutes. After that he washed it out. It had the same result as the brazilian blowout thing, but it wasn't that. That's all i know.
I want to know what it was, and how long it will last. Thaaank you!! :]

1 AnswerSinging1 decade agoJob application question?
i am filling out a job application for a restaraunt and i am 17. There is a question that asks why i am applying for a position there... I feel like if i say i love the food and all that, it's kissing up...but i don't think they want to hear that i am doing it for money. I really do like the place, but i am also doing it because i need money... also, they serve alcoholic drinks and said "under what circumstances would you not feel comfortable serving alcohol?" i am 17, so i am unsure what to say for that. I really need help! Thank you so much!

2 AnswersPerforming Arts1 decade agoWhat is wrong with my bunny?!?
my bunny brownie died just a couple days ago. She had tumors and couldnt walk anymore. The vet was not sure if the tumors were the cause, however. Brownie left behind her lifelong companion and now that bunny seems sick. Brownie had been sick for months but just 2 days before she died, her friend started acting weird. The bunny that is still alive does not lift up her head. At first, we thought she was sad but it became apparent that she cannot walk because her front legs dont work right. They spread out to her side, which is what happened to brownie except with her back legs. We dont know if both of the animals sicknesses are related but we dont want to lose another bunny! Vets dont even know and we need help! Pleaase help!
