Answer:
0.1 atoms
Step-by-step explanation:
Typically, there is 0.1 atoms in each cubic centimeter of interstellar wind, and 10 ions in each cubic centimeter of solar wind (versus surface air which contains 3 x 10^19 molecules per cc). This means there is a great deal of dead space between the very tiny particles and collisions are rare.
Set them up like this example:
4 8
_ = _
6 12
cross multiply by multiplying 4 by 12 and 6 by 8.
If they are equal then it is proportional.
So the formula y= ax^2 first you must flip the equation so that gives us ax^2= y
Then divide both sides by x^2 giving us <span><span>a<span>x^2/x^2 = y/x^2 so we would end up with a= y/x^2 </span></span><span /></span><span><span /></span>
Answer:
A, they are skew
Step-by-step explanation:
Skew means that they are not perpendicular and they are not parallel.
