Current density of solution a/m2 is given below

Step-by-step explanation:

Current density is the measure of current generated per unit surface area of electrode.

Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,

CD= Current/(projected area of electrode)

area of rectangle= LxB= 5cm x 2cm =10cm2

CD= 200mA/10cm2

CD= 20mA/cm2

Your Current will be 200mA.

Current density will be 20mA/cm2.

Can someone step by step explain the answer please

Answer: z = $\sqrt{10}$

Step-by-step explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

$\frac{a}{x} =\frac{x}{b}$

You can use 5 as a and 2 as b to complete the proportion:

$\frac{5}{z} =\frac{z}{2}$

Next, to solve:

Step 1: Cross-multiply.

$\frac{5}{z} =\frac{z}{2}$

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z

I hope this helps!

The sum of two numbers is seventeen. Three less than three times the smaller is equal to the larger

tia_tia [17]

The numbers are 5 and 12.
Smaller number = x
Larger number = y
x +y =17
y = 3x - 3
x +3x -3 = 17
4x = 20
x = 5
smaller number is 5
y = 3(5) - 3
y = 12
larger number is 12.
