A material will float on the surface of a liquid if the material has a density less than that of the liquid. given that the dens

ity of water is approximately 1.0 g/ml, will a block of material having a volume of 1.3 104 in3 and weighing 350 lb float or sink when placed in a reservoir of water?

We will first convert lb to grams and in³ to milliliters. 
350 lb : 2.205 = 158.75733 kg = 158,757.33 grams
1.3 · 10^4 in³ = 13,000 in³ = 13,000 · 0.016387064 = 213.031 liters 
213.031 liters · 1,000 = 213,031 milliliters
Density = m / V = 158,753.33 g / 213,031 ml = 0.7452 g/ ml
Answer: A block of material will float.

What factors determine the magnitude of the electric force between two particles ?
svp [43]
The electric force between the two particles are calculated through the equation,
 
                          F = kQ₁Q₂ / d²

where F is the force, k is a constant called Coulomb's law constant, Q₁ and Q₂ are the charges, and d is the distance. This equation is called the Coulomb's law. 

It can be seen from the equation above that the electric forces between the objects are majorly affected by the substance's charges and distance. 

The answer to this item is therefore letter A.
