Example:
Mass = ?
Density = 25 g/mL
Volume = 5 mL
therefore:
d = m / V
25 = m / 5
m = 25 x 5
m = 125 g
hope this helps!
Answer: capillary action
Explanation: it occurs when the adhesion forces (attraction between two surfaces or substances) in the liquid are stronger than the cohesion forces (attraction between the same molecule)
Answer:
Intermolecular forces
Explanation:
Intermolecular forces cause surface tension.
Source info:
"Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions."

Answer:
2.45Joules
Explanation:
since kinetic energy is K.E.=1/2m
lost in potential energy is gain of kinetic energy
mgh=1/2mv^2
9.8*2*0.5=v^2
=9.8
v=
=3.13m/s
now k.e. = 0.5*m* =0.5*0.5*9.8 =2.45J
