Home work home work....

tolong carikan definition dari istilah2 dibawah ini:

*inflation
*Economy's gross domestic product
*interest rates
*exchange rates
*balance of payment
*debt
*federal budgets
*fiscal policy
*monetary policy
*labour policy
*economic growth

Jhansen dodol. cari lah dikamus business on line... pake tanya2 segala lagi.. dah tau internet situ 24 jam. dodol ah

da terjawab pun....lama bener kasih jawaban...

parah juga....

huh... kl u pinter ya kerjakan aja sendiri ngapain pake post2 sini... bikin semak aja loh... jhansen emang mau eprnag mulut yah? ga bakal menang lu... eh.... jaan2 yuk kapan2 ngumpul ank meth2 di disini....

namany juga section PR ma UJIAN??

cemana nya ente....

weleeehhh weleeeehhh............................................................

makin lama makin aneh ar... posting yang benar jrit.....

---> aneh neh orang.... bisa bilank posting makin aneh... malam memperaneh lage... hm... btw... "jrit" itu apaan? jerit seh wa tau ( typo y? )

Ya udah, jangan OOT lagi

ada yang mau bantuin kerjakan assignment ku untuk bulan depan

1. A mass m = 0.70 kg slides along the x-axis of a horizontal frictionless surface with speed vx = 2.2 m/s. It runs into a relaxed spring oriented along the x-axis. The spring had previously been observed to stretch by 3.8 cm when it was oriented vertically with the mass suspended from it.
(a) Find the spring constant of this spring
(b) What is the maximum compression of the spring when the mass runs into it?
(c) The mass rebounds as a result of having compressed the spring. What is its velocity when it leaves contact with the spring?

2. A satellite moves in a circular orbit around Earth at a speed of 5000 m/s. Determine
(a) the satellite’s altitude above Earth’s surface and
(b) the period of the satellite’s orbit.
[Given that the Earth’s mass is 5.98  1024 kg and the Earth’s radius is 6.38  106 m.]

3. The Earth’s orbit is slightly elliptical. In fact, the Earth is closer to the Sun during the northern hemisphere winter than it is during the summer. Is the speed of the Earth during winter greater than, less than, or the same as its speed during summer? Explain.

soal nomor 1 wa agak kurang mengerti...jadi wa jawab soal nomer 2 aja yah..hoho...
2 a) Pake rumus F centripetal = F gravitational
cari r
ntar dapatny r = 1.60 X 10^7
untuk cari altitudeny kurangi r yg di atas ama jari2 bumi
ntar dapat altitude = 9.62 X 10^6 ( betul ga yah?)

b) Pake rumus omega (w) = 2 phi / T
omega bisa diganti jadi v/r
jadi T = 2 phi X altitude / kecepatan satelitny
jawabanny T = 1.21 X 10^4

mudah-mudahan jawabanny betul...kurang yakin seh...
hoho...
acek coba kerjakan dulu soal ini...(correct me if I make a mistake)
klo ada yg kurang jelas silakan nanya

buat nomor 3 wa gak tau jawabanny...kurang bisa teori...

ada juga yang bantu

jadi segan

masih belum bisa itu semua

sudah lupa rumus nya

nanti belajar ah

3. The Earth’s orbit is slightly elliptical. In fact, the Earth is closer to the Sun during the northern hemisphere winter than it is during the summer. Is the speed of the Earth during winter greater than, less than, or the same as its speed during summer? Explain.

Ans: Kalo g salah yg nomor 3 ada hukumnya e: Wkt yg dibutuhkan utk bergerak sepanjang orbit elips pada setiap titik itu sama. Jadi kalo pd saat bumi dkt dgn matahari (musim dingin di kutub utara), kecepatannya jadi besar dan pada saat bumi jauh dr matahari (musim panas di kutub selatan), kecepatannya lbh kecil sesuai dgn hukum tadi. Dah lupa nama hukumnya apa lolz.

1.a) F spring=F mass
k . x = m g
k = (0.7 x 9.81) :0.038
k = 180.7 N/m
jawab yg mudah e dl.... yg laen menyusul...

1.b) conservation energy:
Ek mass = E spring
1/2 m x v^2 = 1/2 k x X^2
0.7 x (2.2)^2 = 180.7 x x^2
x = 0.137 m = 13.7 cm
moga2 bener

1.c) conservation juga... E setelah kena pegas berarti double karena energi pegas juga di + kan... (moga2 ga salah)
2E = 1/2 m . v2^2
2 . v1^2 = v2^2
v2 = 3.11 m/s
(juz coba2... kalo sala tulung diedit)
thx

jadi di bantu

padahal cuma asal taruh biar gak kosong ini thread

<roflmao>

lol... cara ini boleh kita tiru tatsu... buat membangkitkan thread kita yg telah "tewas"

yang mana saja yang tewas, biar di bantu

homework??? BOOOOOO!!!!

PR sekolah..??
tuh uda masa2 lalu...wwkkwkwk...
datang ke skul pagi2 n nyontek punya tmn,kwkwkw...
sapa setuju?
