Which statement compares the strengths of electric forces between particles of matter? Please don't just guess for points, if your answer is wrong i'll report it.
A. Hydrogen bonds are stronger than ionic bonds but weaker than Van der Waals forces.
B. Metallic bonds are stronger than hydrogen bonds but weaker than ionic bonds.
C. Hydrogen bonds are weaker than Van der Waals forces but stronger than metallic bonds.
D. Metallic bonds are weaker than hydrogen but are stronger than ionic bonds.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
