what are some characteristics that are important if i want to become an engineer?

for some reason i keep thinking im not good enough. im a junior in high school and im not outstanding in math but not horrible eaither. i like when i understand it but im kinda slow at it most of the times. sometimes ill spend 20 minutes (or more) trying to figure out a problem... is that a good characteristic? im taking pre cal now (well more like trig). its such a beeyotch!
i do like the hands on science part. experiments are fun for me but im not too crazy about the equation stuff with it.

is this a good choice for me???

Im horrible at math and I can't seem to pay attention in class because I get lost and then stop listening. usually my friends help me but they aren't here right now.
y< x+2 (in a cube root)

they want me to graph it. I dont know how to start. I know itll be complicated to explain but try your best.

Someone I know eats all the time. I try telling her it's not good. But she is frequently munching (good thing it's usually not high calorie foods), but she can go on munching. She is slender, but she is always nibbling. Will this kind of eating precipitate Type II diabetes?

Here what is says:

One whimsical statement of the laws of thermodynamics - probably not one favored by gamblers - goes like this:

I. You can never win; you can only lose or break even.
II. You can only break even at absolute zero.
III. You can never get to absolute zero.

What do you mean by "win, "lose," and "break even?"
[Hint: Thank about a heat engine.]

What does this mean??? I have absolutely no clue. HELP!!!

What is a 22-year solar cycle?

a.It refers to a periodic variation in the number of sunspots, their latitudes, and their magnetic polarities.

b.It is the time it takes the Sun to complete one revolution about the center of mass of the Solar System.

c.It refers to a periodic variation in the size, luminosity, and temperature of the Sun.

d.Every about 22 years, the magnetic field of the Sun reverses.

e.It is the time for a typical plume of gas to rise from the bottom of the convection zone to the top of the convection zone, or the bottom of the photosphere, and then to sink back to the bottom of the convection zone.



Which of those above statements is true?? Thank You

If im not mistaken D is true, but could A be right also?

Your helps appreciated

Maybe we are all just atoms that make up a bigger thing. If you have ever seen one of the start of the simpsons, it starts off as them sitting in the couch and then it starts zooming out so you can see the earth, then the solar system, then the galaxies, then a galaxie cluxter and the zooms out of the universe and then it zoom out of homer head! and then it just shows them sitting in the couch agian. Have you ever noticed how all planets are round like atoms.

And another thing is that have you have thought about how big the universe is! Like its HUGE just thinking about it makes me feel so little and worthless to the universe. One more thing.

There IS such thins as aliens!!! like think about it, we were definetly not the first living beings, there had to have been many more before us on some other planet. There has to be, they might not beas advanced or they maybe 20x times past the technology as us.

These are just a few thought that i had.... please tell me what you think.
