Apositive charge is located at the middle of an imaginary cube (call it cube a). the cube size is cut in half to make cube b and then enlarged to double its initial size to make cube c. which of the cubes has the largest net electric though its suface?
a. cube b (smallest cube)
b. cube a (initial cube)
c. the net flux is zero through each cube
d. cube c (largest cube)
e. the net flux is the a same non-zero value in each cube.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

there is no answer sorry!

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
