Answer:
The answer is C I believe.
Step-by-step explanation:
The mean is 35/5=7
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
Answer:
<h3>The given statement "The force F between two charges
and
in a vacuum is proportional to the product of the charges and is inversely proportional to the square of the distance between two charges" is a <u>Coulomb's law.</u></h3>
Step-by-step explanation:
Given that "The force F between two charges and in a vacuum is proportional to the product of the charges and is inversely proportional to the square of the distance between two charges"
<h3>The given statement is a <u>Coulomb's law.</u></h3>
Coulomb's law states that the magnitude of the electrostatic force F of attraction or repulsion between the two point charges and is directly proportional to the product of the magnitudes of charges and and it is inversely proportional to the square of the distance between the two charges.
Answer:
Part 3)
Part 4)
Step-by-step explanation:
Part 3)
<em>step 1</em>
Find the value of x
In the right triangle of the figure we know that
The cosine of angle of 30 degrees is equal to the adjacent side to angle of 30 degrees divide by the hypotenuse
so
and remember that
substitute
Simplify
<em>step 2</em>
Find the value of y
In the right triangle of the figure we know that
The sine of angle of 30 degrees is equal to the opposite side to angle of 30 degrees divide by the hypotenuse
so
and remember that
substitute
Part 4) Find the value of x
Applying the Pythagoras Theorem
Simplify
