Answer:
I Think its ABC
Explanation:
No air is the lightest
Helium is lighter than regular air that's why it goes up so then the regular air would be heaviest.
This is a conversion problem. 760 Torr is equal to 1 atmosphere. so we can can solve now. 5,550torr*(1atmosphere/760torr)=7.3atmospheres. since the two torrs cancel out with cross multiplication we are left in atmosphere units.
Answer:
<h3>

</h3><h3>
Explanation:</h3>
Let U1 and U2 be the gravitational potential energy of the first and second stone respectively.
U1 is given by:

and U2 is given by:
therefore, comparing the energies we have:

therefore:

Answer:
The height (h) will be:
Explanation:
The scape speed equation is given by:

Now, the speed of the missile is


Using the conservation of energy, we can find the maximu height of the missile.



Let's recall that g = GM/R², using the equivalence principle. When R is the radius of the earth and M is the mass of the earth.

Therefore the height (h) will be:
