Answer:
The first picture's area of least repulsion is the areas of the outer portions where the souths are pointing. The second picture's area of least repulsion is the area in the inner part
Explanation:
The charge of an atom before any electrons are transferred is zero.An atom as a whole is electrically neutral.
An atoms contains same number of electrons and protons. The charge of an electron and a proton is equal in magnitude but opposite in sign. The charge of a proton is 1.6 x 10⁻¹⁹C and the charge of an electron is -1.6 x 10⁻¹⁹C .Thus the charge of all the protons in an atoms is neutralized by the total charge of all the electrons.Thus an atom is electrically neutral.
when an atom loses electrons , it acquires a positive charge and when it gains electrons, it acquires a net charge.
<span>Mind mapping has many benefits over linear text notes.The visual aspect of mind maps allows you to use mindmapping for a wide variety of things.Practical examples of when you should use mind maps over text notes.</span>
All the mind maps created are done by Mindjet MindManager – our favorite mindmapping software. Also, all the ideas outlined here will give you an introductory idea on how to utilize mind maps for certain scenarios. I highly encourage you to explore on your own on how to implement mind maps as the technique is easily malleable for different purposes. So let’s start with the first example.
Explanation:
Draw free body diagrams for each mass.
There are 3 forces on the disk: weight force mg pulling down, normal force N pushing up, and tension force T pulling right.
There are 2 forces on the cylinder: tension force T pulling up and weight force 3mg pulling down.
Sum of forces on the disk in the centripetal direction:
∑F = ma
T = m v²/r
Sum of forces on the cylinder in the vertical direction:
∑F = ma
T − 3mg = 0
T = 3mg
Substituting:
3mg = m v²/r
3gr = v²
v = √(3gr)
Plug in values:
v = √(3 × 10 m/s² × 0.800 m)
v = √24 m/s
v ≈ 4.90 m/s
Amagat's law of additive volumes states that we can simply add up the individual volumes of each gas (provided they are at the same temperature and pressure) to get the total volume of the mixture. Conservation of volume is an acceptable assumption for gases (but not always for liquid mixtures). This works for gases since the molecules are very small and only take up a minimal amount of space in a gas.
