Answer:
the sun i think because the sun has the greatest gravitational pull
They are used to make plane bodies.
Some are used for electrical wires eg copper because they are good conductors of electricity.
Used in building materials.
used to make jewelry eg gold and silver<span />
but heres a way to solve it
An athlete takes a deep breath, inhaling 1.85 L of air at 21°C and 754 mm Hg.

Answer:
<h3>D)Moon and sun</h3>
Explanation:
Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.
hope it helps:)
<h3><u>Answer;</u></h3>
= 5.1 g/L
<h3><u>
Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Number of moles is 1 since one mole has a mass equivalent to the molar mass.
Therefore; We can find the volume and thus get the density.
<em>V = nRT/P</em>
<em> = (1 × 0.08206 × 237)/3.510</em>
<em> = 5.5408 L</em>
<em>Hence; Density = mass/volume </em>
<em> = 28.26 g/5.5408 L</em>
<em> = 5.1 g/L</em>
<em>The Density is 5.1 g/L or 0.005 g/cm³</em>
