It is found experimentally that the electric field in a certain region of Earth's atmosphere is directed vertically down. At an
sweet-ann [11.9K]

Answer:

1.176604*10^{-10} C

Step-by-step explanation:

This is flux problem (see diagram below)

Since electric field is vertical to the top and bottom of the cube. total flux will be sum of flux up and down i-e

Фtotal=Фup + Фdown = Ф 260 + Ф150

But flux is given by scalar product of Electric field and area

Ф=E.A= EA cos∅

where ∅ is the angle between two vector quantities E the electric field and A the area vector. So, total flux is

Фtotal = =E_{260} .A+E_{150} .A

=E_{260} *A cos \alpha +E_{150} *A cos \beta

=E_{260} * Acos(180)+E_{150} * Acos(0)

=-E_{260} .A  +E_{150} .A

=A(E_{150} -E_{260} )

But we know that according to Gausse's Law total flux is given by;

Total flux = q / ∈

==> q= ∈(Total flux)

q = 8.84 *10^{-12} *110^{2} (260-150)

q=1.176604 *10^{-10} C

Explain what it means to be a solution when there are two lines on a graph
Wittaler [7]

Answer:

Step-by-step explanation:

When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations.

-2 and suki was right aDriene was wrong as he added

Step-by-step explanation:

-8-(-6)

-8+6        (it becomes positive 6 as a negative and negative give u a positive )

If y=5-3 and 3x-y=-1 what is the value of y
Oksana_A [137]

Answer: The value of y is 2

Step-by-step explanation:

If y=5-3 and 3x-y=-1

Take y=5-3 first

y = 5 - 3

y = 2

Then, take 3x-y=-1, and put y = 2 in the Expression

3x-y=-1

3x - (2) = -1

3x - 2 = -1

3x = -1 + (-2)

3x = -1 -2

3x = -3

To get x, divide both sides by 3

3x/3 = -3/3

x = -1

Thus, the value of y is 2 while x is -1
