B. moving electric charges, hope this helps :)
Answer:
The mass of the products and reactants are the same on both sides of the equation.
The number of atoms of products and reactants are equal and hence it proves the law of conservation of mass.

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
Answer:
a)1.14
b)0.31
c)1.14
d)0.25
Explanation:
Assume wave travels in a harmonic motion. This means if it takes 2.8 for the boat to travel from highest to lowest point, then it'd take 2.8*2 = 5.6 for the boat to travel in 1 period (from highest point to lowest point then back to highest point again).
a)As the wave crest is 6.4 apart. Then it's speed is
v = s/t = 6.4/5.6 = 1.14
b) The amplitude would be half of the vertical distance traveled by the boat, which is
A = 0.62 / 2 = 0.31
c) As the distance between the crest and the time it takes for the boat to travel vertically is unchanged, then the wave speed would stay the same:
v = 1.14
d) The amplitude would again be half of the vertical distance
A = 0.5 / 2 = 0.25
