Waves transmit both energy and momentum.

a physics web quiz problem worthy of remembering

Consider a block of mass m attached to a vertical spring with spring constant k. When on earth, for small oscillations the period of the system is T. Now it is taken to a planet where the acceleration due to gravity is g/4. If the new period is T1 then

T1 = T

man o man i am going to be praying heavy tonight. i got both a physics exam and an electronics exam tomorrow. see what i gotta cram in?

i want

this ece problem is easy

i am feeling sexy

friends only entry

warning: the entry is very graphic, and i would not recommend reading it if you do not want to know anything about my sex life. just skip over.

1) Dogs lie around all day, sprawled on the most comfortable piece of furniture in the house.

2) They can hear a package of food opening half a block away, but don't hear you when you're in the same room.

3) They can look dumb and lovable all at the same time.

4) They growl when they are not happy.

5) When you want to play, they want to play.

6) When you want to be alone, they want to play.

7) They are great at begging.

8) They will love you forever if you rub their tummies.

9) They leave their toys everywhere.

10) They do disgusting things with their mouths and then try to give you a kiss.

Conclusion: Dogs are tiny men in little fur coats

weh. lots of things have happened today, and more stuff is to come. i expected a guest to stay over tonight. there is like a 2-day long program going on campus where they take young 8th grade girls, and expose them to college. they are encouraged to study math and sciences, and they spend a day long seminar leanring various things and doing projects. then they go to a basketball game at the evening, and then they will stay with a host (me) for the night who is either a math/science/engineering type of role model.
i just got done cleaning the dorm, i even cleaned the coffee pots. my bed is made, the floor is clean, the rug is clean, i organized all the items on my shelf neatly, emptied the trash, oh i need to spray good smelling stuff for a finishing touch.

my roomate did nothing. i personally think that she needs to clean a bit more. i know she used some of my coffee pots to heat up water, but it leaves water stains. and she pretends to sweep the floor, when all she really does is sweep it into a wall corner and not sweep it into the garbage can. she takes off her boots in the room when she should take them off outside the room and carry them into her closet. i have to post signs all over the door reminding her to take off her shoes, otherwise she would walk all over the room and on the carpet leaving a trail of mudd and ewww stuff just like a dog does. i am starting to think i am the only one looking at the floor. other than that, i think we are cool.

oh i found the electronic part that i lost a few weeks ago. i found it while sweeping a little bit underneath the bed. i have no idea how it got there.

i am doing laundry. i should slap myself. dad offered to buy me laundry stuff when he came and visited. i was stupid and thought i had it all. well i need to stock up on stuff. i will probably take a ride to target and charge it. that reminds me, i need to work. i need to work i need to work.. i need money.....

dad is that check in the mail for my road trip?

i haven;t talked to dear old dad in a few days. i know he reads my diary entries, public ones at least. this is a great way to learn about your daughter. too bad dad doesn't have one.

for dinner i had pasta with alfredo sauce and broccoli, not very much, i am serious, it was like a cup or a cup and a half and i got charged $3.50. i had that and a pop for dinner while talking to lisa, nikki, and few other people, mostly apo bros. got advice on stuff i posted earlier. thanks girls =)

what else? oh i had two exams today. i think i did well but i don't want to jinx myself about prematurely congratulating myself on stuff. i probably made a few stupid mistakes. i am usually one of the last ones to finish taking the exa, that's because i take the time to go back and check every single proble, every equation, etc.. to look for dumb mistakes, and i find quite a few. of course it is horrible to see everyone else leave and be the last one there, but i'd rather be right than wrong or , well, er,, confident....


so i am waiting for the results of the exams. i know for my electronics exam, the prof will have it graded like asap, because engineering exams, all he does it grade you on ANSWERS and gives little credit for wrong answers, if any. butthead. in engineering it is either right or wrong, not like english or writing, or some liberal arts , where you can be opinonated about your answers. that would be hilarious if engineering problems were like that. well it would not be a very safe world. i mean, if it wasn't right or wrong and just opiniated, then engineers could get away with designing bad things like bad bridges, hair dryers that explode, computers that don't work, etc..etc..

checked school e-mail... no test results yet.....

physics , i should get the exam back by like next wednesday, i think...
