We all know that a soccer ball is composed of matter, and matter is made up of particles of atoms such as protons and electrons, and matter of soccer ball can also be made up of waves of electrons and protons. This is now in a realm of quantum mechanics were everything defies our logic and common sense. Atoms can be defined as particle and also as a wave, they called it particle wave duality, it means atoms behave as wave and a particle. This is the trickiest part, Imagine that you are not observing the flight of the soccer ball, it actually behave as a wave as it moves in its trajectory, but at the moment that you are going to observe the flight of the soccer ball, it will behave as a particle as you see on its trajectory, becoming a ball or a particle, and that is the weird of part of quantum mechanics, the world of subatomic particles defies all common sense or logic. Remember that we will never see the wave like motion of any particle, because nature always plays a trick on our mind or senses.
Answer:
50 degree.
Explanation:
Given that the components of vector A are given as follows: Ax = 5.6 Ay = -4.7
The angle between vector A and B in the positive direction of x-axis will be achieved by using the formula:
Tan Ø = Ay/Ax
Substitute Ay and Ax into the formula above.
Tan Ø = -4.7 / 5.6
Tan Ø = -0.839
Ø = tan^-1(-0. 839)
Ø = - 40 degree
Therefore, the angle between vector A and B positive direction of x-axis will be
90 - 40 = 50 degree.

Explanation:
To convert milliliters to liters, we divide by 1000.
To convert milliliters to grams, we multiply the volume (in ml) by the density (in g).
