The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules. ... Water wants to stick to the glass and surface tension will push the water up, until the force of gravity prevents further rise.
Narrower tube openings allow capillary action to pull water higher

Explanation:
Remark
This is a momentum question. Both cars are sitting still (v1 and v2 are both 0) to start with). When the spring is sprung), they both move but in opposite directions.
Let us say that v4 is minus.
Equation
0 = m3*v3 - m4* v4
Givens
m3 = 1750 kg
m4 = 1000 kg
v3 = 4 m/s
Solution
m3*4m/s - m4*x = 0
1750 * 4 - 1000*x = 0
1750 * 4 = 1000x
7000 = 1000 x
7000/1000 = x
x = 7 m/s

a sound wave is an electromagnetic wave
<h2>Answer: The mass will remain the same, but the weight will change
</h2>
Let's start by explaining that mass and weight are very different concepts.
Mass 
is the amount of matter that exists in a body, which only depends on the quantity and type of particles within it. This means mass is an intrinsic property of each body and <u>remains the same regardless of where the body is located. </u>
On the other hand, weight 
is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass of the body by the acceleration of gravity 
:
Then, since the Earth and the Moon have different values of gravity, the weight of an object in each place will vary, but its mass will not.
Weight on moon = (0.16) • Earth weight
