The total displacement of the person walking from point A to point B is 300 yards.
As shown in the figure we can conclude that the required method to calculate the total displacement is the Pythagoras theorem.
<h3>Pythagoras theorem in brief :</h3>
According to the Pythagorean Theorem, the square that represents the hypotenuse, or side of a right triangle that faces the right angle, is equal to the total of the squares on the triangle's legs.(or, in popular algebraic notation, 
).
<h3>Calculation: </h3>
Let,
a = 500
b= 300
Hence by using Pythagoras' theorem
Total displacement of the person = 
= 
= 
Thus the total displacement of the person from starting point is 300 yards.

Generally the magnetic field is mathematically represented as
Where 
is the permeability of free space with a constant value
And the given distance where the magnetic field is felt is r = 0.9 cm = 0.009 m
Now substituting values
Fro the second question the distance of the position considered from the center is r = 1.2 cm = 0.012 m
So the magnetic field is
Answer:
True we need greenhouses for carbon dioxide
Answer:
True
Explanation:
There are 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms, therefore the subscript 9 belongs.
