There are a few questions, thanks for any help!
1. What size of quilters ruler would be best to invest in?
2. If the pattern says 1/4" seams, does that mean I measure a 1/4" on each patter and sew them together at that point?
3. Do I make it long enough to fold over so I can sew it together and stuff it, or can I sew the pattern to a plain white blanket?
4. Any websites you can recommend for a beginner?

Ok so here is the question:
A 62-kg bungee jumper jumps from a bridge. She is tied to a bungee cord whose unstretched length is 12m, and falls a total of 31m. (a) Calculate the spring stiffness constant, k, of the bungee cord, assuming Hooke's law applies. (b) Calculate the maximum acceleration she experiences.
Ok so I am not sure if for a, whether I should use the equation
F=(1/2)kx^2, and if so, is F just mg?
Or if I should use this equation:
E=KE(i)+GPE(i)+SPE(i)= KE(f) + GPE(f) + SPE(f)

Ok so I am knitting a hat on circular needles. I purchased my circular needle at Walmart and they only had one size for the cable I think it might be 24" or else 20 or something. Anyways so I am decreasing, but I think the cable is too long to finish it off. Is there anything I can do? Or should I just keep trying it with the long cable?4 AnswersHobbies & Crafts1 decade ago
Ok so I tried to go vegitarian and lasted about two weeks. I always felt tired, lacking in stamina. I do think that animals are meant to be eaten, but definately not as much as we eat them. I have a veggie day once each week, sometimes two or three times and I feel better than ever. So it has made me question how healthy it really is? Maybe I just have meat eating genetics or something. what are your opinions, did you feel bad in the pregression from meat eater to vegitarian?6 AnswersVegetarian & Vegan1 decade ago

2.) Lim 5000x^2/sinx + 5000x^2
3.) Lim sin(1/x)

I am a high school student, and i don't really have very much confidence in myself about social interactions. Anyone who has been unconfident, and is now confident, I would like to hear your story. And maybe something inspiring to keep me going. Does it get easier as you get older? Also people that are also lacking confidence, maybe some of your feelings.
Sometimes when I tak to people I think about whether or not they like me, and my goal is to not care if they like me or not.4 AnswersOther - Family & Relationships1 decade ago
