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.
3(n - 8) = -15
3n - 24 = -15
3n = -15 + 24
3n = 9
n = 9/3
n = 3 <==
It would be B because you have to divide both sides by -2 to isolate the y !
Answer:
Step-by-step explanation:
sin A = 
Sin 29 = 
0.4848 * 500 = y
y = 242.4 ft
Answer and Step-by-step explanation:
Question 4:
We need to solve for y, so we need to use the cosine trig function, which is adjacent divided by hypotenuse.
Question 5:
We need to use the sine trig function, which is opposite divided by hypotenuse.
