Answer: find the answer in the explanation
Explanation:
The capillarity of water molecules is different from the mercury molecules.
What is capillarity ?
This is the tendency of a liquid substance to rise in a capillary tube.
Molecules water rises up in a harrow tubes because of the force of adhesion between the water molecules and the tube molecules is greater than the force of cohesion between the water molecules. This helps water to wet the tube and rise. While mercury which is also a liquid falls in a narrow tubes to level below the outside surface because the force of cohesion between the mercury molecules is greater than the force of adhesion between the mercury molecules and the tube molecules. Mercury does not wet.
Answer:
kg m/s
Explanation:
e = Charge = C
V = Voltage = 
c = Speed of light = m/s
Momentum is given by
The unit of MeV/c in SI fundamental units is kg m/s
Answer:
the speed of a jet plane = v = 12 m/s
Explanation:
jet plane that travels 48 meters East in 4 seconds?
<u>use the velocity as distance over time formula = v = d / t</u>
where:
t = 4 sec
d = 48 m
plugin values into the formula
v = <u> 48 m </u>
4 sec
v = 12 m/s
therefore,
the speed of a jet plane = v = 12 m/s
