It is found experimentally that the electric field in a certain region of Earth's atmosphere is directed vertically down. At an

altitude of 260 m the field has magnitude 60.0 N/C. At an altitude of 150 m, the magnitude is 100 N/C. Find the net amount of charge contained in a cube 110 m on edge, with horizontal faces at altitudes of 150 and 260 m. Neglect the curvature of Earth.

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

Translate the following sentence into an equation, then find the number. Five times a number less than 18 is is equal to 13.​
Nata [24]

Answer:

The answer would be 5x-18=13

Step-by-step explanation:

When given five times than a number, 5 would be multiplied by (x) since x can be any number. Less than 18 means subtract 18. Is equal to means an eual sign and the equation is equal to 13.
