Military specs oftan call for electronic devices to be able to withstand accelerations of 10 g. To make sure that they do, manufacturers test them using a shaking table that can vibrate a device at various specified frequencies & amplitudes. If a device is given a vibration of amplitude 9.7 cm, what should its frequency be in order to test for compliance with the 10 g requirement (ans in Hz)?
d = v*t + 0.5*a*t^2 = 9.7sin(x*t)
take the derivative
v + a*t = 9.7x*cos(x*t)
take the derivative
a = 9.7*x^2*-sin(x*t)
so:
10g = 9.7*x^2
x^2 = 10*9.8/9.7
x = 10.1
2pi = 10.1*T
T = 0.62 sec
freq = 1/T
freq = 1/0.62
freq = 1.61 Hz

s. I do enjoy the power and control I have over him...when I smoke cigarettes and wear tight jeans, but I am wondering if this is an obssesion of his that will cause problems down the road? Anyone ever experienced this?

A blonde calls her boyfriend and says, "Please come over here and help me. I have a killer jigsaw puzzle, and I can't figure out how to get it started."
Her boyfriend asks, "What is it supposed to be when it's finished?"
The blonde says, "According to the picture on the box, it's a tiger."
Her boyfriend decides to go over and help with the puzzle. She lets him in and shows him where she has the puzzle spread all over the table.
He studies the pieces for a moment, then looks at the box, then turns to her and says, "First of all, no matter what we do, we're not going to be able to assemble these pieces into anything resembling a tiger."
He takes her hand and says, "Second, I want you to relax. Let's have a nice cup of tea, and then.....," he sighed, "let's put all these Frosted Flakes back in the box.

My boyfriend is so wonderful, but he does not like kissing like I do. Recently I started the touches early in the morning and he hold my hand to stop it. But we did not sleep thoroughly the whole night. Can that be the reason or what. We do not stay together and I wanted to get the best of him that morning.

My native-German husband is 36, six foot, and weighs 270 lbs. He has high BP and is pre-diabetic. Five years ago when we were engaged, he was 190. He cooks and eats what he wants, drinks about 4 to 6 drinks an evening - up to 18 drinks on a weekend day. He has food binges late at night while watching violent movies after I go to bed. When we got married, my impression of him was of an active, outdoor kind of guy who was into lifelong fitness. Not one to nag, I've recently tried to be helpful with, "I love you and want you to be well", do it for our son, healthy food suggestions, be inspired by his father's own efforts, enlisting help from his brother as a 'gym buddy', trying to do active things together, modelling good behavior, etc. Zip. BTW, I'v also asked him to get help with his drinking and he insists he doesn't have a problem. At a rough spot in our marriage, I tried ultimatums. Funny thing, he also makes fun of other fat people we know and of me doing yoga. HELP!

I recently went to Thailand and was chatted up in a bar by a "girl" with a cracking ****.
It looked just like a hot woman and ended up giving me a nosh(which was great(deep throating so tears in eyes(which most women dont know is the best technique)) it was fantastic.
However the next night me and some friends went to a lady boy show where the previous nights conquest was doing cabaret. But I still fancied it.
As it looked like a woman but was a guy am I gay now?

These two elements seem to be exceptions to the larger rule that atoms with an odd number of electrons are paramagnetic and elements with an even number of electrons are diamagnetic. If anyone knows, or better, knows a good place I could read about this, that would be wonderful. My electromagnetic theory book doesn't say why this is, only that it is. Thanks!
