When giving directions to your house, you tell
someone to drive two miles east, then three
miles north, then one mile west.
What are the components of a vector that
points from his house to yours?
1. The east component of the vector is three
miles; the south component is 3 miles.
2. The east component of the vector is 1
mile; the south component is 3 miles.
3. The west component of the vector is 1
mile; the north component is 3 miles.
4. None of these.
5. The east component of the vector is 1
mile; the north component is 3 miles.
6. The west component of the vector is three
miles; the north component is 3 miles.
7. The west component of the vector is 1
mile; the south component is 3 miles.

A 1.509 g sample of asmium oxide which melts at 40 C and boils at 130 C degrees is placed inot a cylinder with a movable piston that can expand against the atomospheric pressure of 745 torr. Whe the sample is heated to 200 degrees c, it is completely vaporized and the volume of the cylinder expandes by 235 mL. What is the molar mass of the oxide? Asuming that the oxide is OsOx, find X?

So what do I do? Pl. tell me how to do it. I have to study for the test tomorrow and I need help quickkkkkkkk.

How much water is enough to fully function a 145 pd body. Say you only have like a water bottle full of water. How much mLs of that water would you need to rejuvenate yourself and function normally while trying to preserve as best as possible. How long could the bottle of water last in such a situation? Assuming the person doesn't just chug the whole thing down at once and wants to rationalize it.

It might be easy to answer, but how does it snow? What temperatures does it have to be at for it to snow? How does snow and snowflakes form? I like winter so much I need to know as much as I can about that season and my favorite holiday, Christmas!

Sports drinks generally contain water plus sugars and other minerals, and they are marketed as the most effective way to rehydrate after exercise. What is the basis of this claim? Why can it be detrimental to consume large amounts of these sports drinks if you are not actually exercising?
