Answer:
We know:
V1 = 0m/s
a = 9.8m/s
D = 16m
So we can solve for V2 with a kinematic equation.
V2^2 = 2a*D
V2^2 = 2(9.8)(16)
V2^2 = 313.6
V2 = 17.7m/s
Explanation:
We have that with these disciplines well defined, The Form of accounting that speaks the most Burger Huts situation is the discipline of Management Accounting
Firstly we define the Disciplines of Accounting below
Financial accounting
Financial Accounting, this is a branch of accounting that focuses mainly on the Recording,Encapsulating or Summing up and then Releasing a statement bearing the Affairs of a Business over a specific time frame.
Management Accounting
This Branch of accounting focuses on the use of existing Financial positions to make assessment of a business and determine the best way to move the business forward.
Tax Accounting
This is a branch of accounting that focuses on taxation.This branch is governed by stiff rule that ensure that business stay in check.
Therefore
With these disciplines well defined, The Form of accounting that speaks the most Burger Huts situation is the discipline of Management Accounting

Gravity Gravitational Force of Gravity
Answer:
The x component of the resultant force is -7.27N.
Explanation:
To obtain the x component of the resultant force, first we have to know the x components of the other forces. To do this, we just have to do some trigonometry:
Since both vectors are in the left side of the y-axis, they have a negative x component. So:
Finally, we sum both components to obtain the component of the resultant force:
In words, the x component of the resultant force is -7.27N.
Answer:
Option b. Effective nuclear charge increases as we move to the right across a row in the periodic table
Explanation:
The <em>effective nuclear charge </em>is a measure of how strong the protons in the nucleus of an atom attract the outermost electrons of such atom.
The <em>effective nuclear charge</em> is the net positive charge experienced by valence electrons and is calculated (as an approximation) by the equation: Zeff = Z – S, where Z is the atomic number and S is the number of shielding electrons.
The shielding electrons are those electrons in between the interesting electrons and the nucleus of the atom.
Since the shielding electrons are closer to the nucleus, they repel the outermost electrons and so cancel some of the attraction exerted by the positive charge of the nucleus, meaning that the outermost electrons feel less the efect of attraction of the protons. That is why in the equation of Zeff, the shielding electrons (S) subtract the total from the atomic number Z.
The <em>effective nuclear charge</em>, then, is responsible for some properties and trends in the periodic table. Here, you can see how this explains the trend of the atomic radius (size of the atom) accross a row in the periodic table.
- As the<em> effective nuclear charge</em> is larger, in a same row of the periodic table, the shielding effect is lower, the outermost electrons are more strongly attracted by the nucleus, and the size of the atoms decrease. That is why as we move to the right in the periodic table, the size of the atoms decrease.
