Given data
mass of solute (m) = 1.2 g ,
Volume of solution = 1.5 L ,
= 1.5 × 1000 mL
= 1500 mL ,
What is the concentration of solution = ?
concentration = (mass of solute) ÷ (100 mL of solution)
= (1.2) ÷ (1500 mL of solution)
<em> Note: </em><em> remember to divide both numerator and denominator by 15 to get concentration per 100 ml</em>
<em> Therefore concentration = 0.1 /100 mL ;</em>
<em>The concentration of sugar in a tea is 0.1/100 mL</em>
Use the formula for distance dropped from rest:
D = 1/2 a t^2 .
With no air resistance, you get about 8.8 sec.
I'm pretty sure you can fill in the missing work.
Through the use of electric field lines—of force
The object with the greater mass has a greater gravitational force and that determines what satellites orbit around it. An object with more mass will never orbit an object with less.
