Answer:
The value is 
Explanation:
From the question we are told that
The magnitude of the first force is 
The angle which it makes with the x-axis is 
The magnitude of the second force is 
The angle which it make with x-axis is 
Generally the x-component of the first force is
'
=> 
Generally the y-component of the first force is

=> 
Generally the vector representation of the first force is mathematically represented as
![\vec F_1 = [ -10 i + 17.32 j \ ] \ N](https://tex.z-dn.net/?f=%5Cvec%20F_1%20%3D%20%5B%20-10%20i%20%20%2B%20%2017.32%20j%20%5C%20%5D%20%5C%20N)
Generally the x-component of the second force is

=> 
Generally the y-component of the second force is

=> 
Generally the vector representation of the first force is mathematically represented as
![\vec F_2 = [ 4.33 i - 2.5 j \ ] \ N](https://tex.z-dn.net/?f=%5Cvec%20F_2%20%3D%20%5B%204.33%20i%20%20-%202.5%20j%20%5C%20%5D%20%5C%20N)
Generally the net force acting that point is mathematically represented as

=> 
Answer:
The given vector can be represented in unit vector as

The magnitude of any vector
is given by

Applying values we get

We know that positive x axis in vertorial form is represented as

taking dot product of both the vector's we get

Answer:
There are 6 electrons in the outermost shell.
Explanation:
Sulphur is a non-mettalic element which is in the period 3 and group .6on the periodic table. It has an atomic number of 16 and a Mass number of 32. Atomic number tells you the number of electrons in an electrically neutral atom. It has the electronic configuration of 1s2 2s2 2p6 3s2 3p4.
The orbitals have a formula 2n^2 where n = 0, 1, 2, 3 etc.
In the shells, n = 1 so there are 2 electrons. For n = 2, 2*(2)^2 = 8 electrons. So, 16 - (8 + 2) = 6 electrons in the 3 shell (outermost shell)
Therefore from the electronic confriguration above, there are 6 electrons in the outermost shell.
A. Equal and opposite
For every action, there is an equal and opposite reaction
28J because mechanical energy is the sum of the potential energy and kinetic energy
