god, i feel like i have so much responcabilities, and i dont no what to do, i'm only 13, what do u guys think? :confused:

what responsibilities exactly?
"People Always Lie" - House MD.
like school, home, anywhere
Yep. Life's tough. And the only way to get through it is to be tougher.
Someone said that, but their name it was slipped my mind.
If you think life's tough at 13, just you wait until you leave school.
Wait until you graduate, you gotta worry about finding a job, learning how t odrive, and eventually how to live on your own.
.......
These responsibilities without a doubt will multiply with every year.
:whaaa: I've adopted this smiley
i no
It's not that bad though. Being 24 now myself ( almost twice your age ff babe), I have many responsibilities. You learn to take care of them and how to deal with them more and more independant you grow. At first, I HATED paying for everything by myself. Heh, it felt weird for buying your own food and simple stuff like that.
('-'*)/ - "sup"
cool, thanx
i quess it isn't that bad
<b>Please don't double post. -SD</b>
life sucks, get over it
Life is only what you make of it. you think you have responsibility now, wait til college...
It would be more proper to ask, "What is the mass of planet Earth?"1 The quick answer to that is: approximately 6,000,000,000,000,000,000,000,000 (6E+24) kilograms.
The interesting sub-question is, "How did anyone figure that out?" It's not like the planet steps onto the scale each morning before it takes a shower. The measurement of the planet's weight is derived from the gravitational attraction that the Earth has for objects near it.
It turns out that any two masses have a gravitational attraction for one another. If you put two bowling balls near each other, they will attract one another gravitationally. The attraction is extremely slight, but if your instruments are sensitive enough you can measure the gravitational attraction that two bowling balls have on one another. From that measurement, you could determine the mass of the two objects. The same is true for two golf balls, but the attraction is even slighter because the amount of gravitational force depends on mass of the objects.
Newton showed that, for spherical objects, you can make the simplifying assumption that all of the object's mass is concentrated at the center of the sphere. The following equation expresses the gravitational attraction that two spherical objects have on one another:
F = G * M1 * M2 / R2
R is the distance separating the two objects.
G is a constant that is 6.67259x10-11m3/s2 kg.
M1 and M2 are the two masses that are attracting each other.
F is the force of attraction between them.
Assume that Earth is one of the masses (M1) and a 1-kg sphere is the other (M2). The force between them is 9.8 kg*m/s2 -- we can calculate this force by dropping the 1-kg sphere and measuring the acceleration that the Earth's gravitational field applies to it (9.8 m/s2).
The radius of the Earth is 6,400,000 meters (6,999,125 yards). If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000,000,000,000,000,000 kilograms (6E+24 kilograms / 1.3E+25 pounds).
1 It is "more proper" to ask about mass rather than weight because weight is a force that requires a gravitational field to determine. You can take a bowling ball and weigh it on the Earth and on the moon. The weight on the moon will be one-sixth that on the Earth, but the amount of mass is the same in both places. To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a constant.
