Answer:
0.358g
Explanation:
Density of Helium = 0.179g/L
ρ=m/v
m=ρv
when the volume was 2L
m1= 0.179*2
m1=0.358g
when the volume increased to 4L
m2= 0.179*4
m2=0.716g
gram of helium added = 0.716g-0.358g
=0.358g
1 yard^2 = 0.8361m^2.?

<span>So he spent (.625 x 400) = $250.00 per m^2. </span>
<span>He paid out (500 x 250) = $125,000 on the deal. </span>
<span>He received (500 / 0.8361) = 598.014592 yard^2 of fabric. </span>
<span>That would have cost (598.014592 x 120) = $71,761.75 locally. </span>
<span>He lost (125,000 - 71,761.75) = $53,238.25 on the deal. </span>
You can rework with the incorrect conversion factor.
A.)When heated, the molecules get loser, and the dipole dipole interaction is still there, but they dont stay so closely together, and jossle around with momentary meetings of opposite charges
B.The heat is used to break the bonds between the ice molecules as they turn into a liquid phase<span>. </span>
Answer:
The final position is -69.8 m
Explanation:
Recall that displacement is defined as:
where represents the final position, and the initial position of the object (in our case 83.2 m). Since we also know the displacement (-153 m), we can solve the equation for the final position:
Answer:
Explanation:
The collision is inelastic and can be described by the Principle of Momentum Conservation:
The speed after the collision is:
