Answer:

25 ohms

Explanation:

Hi there!

Ohm's law states that V=IR where V is voltage, I is current and R is resistance.

Plug the given information into Ohm's law (V=50, I=2) and solve for R

V=IR\\50=2R

Divide both sides by 2 to isolate R

\frac{50}{2}= \frac{2R}{2}  \\25=R

Therefore, there are 25 ohms of resistance present in this circuit.

I hope this helps!

Two flat 4.0 cm × 4.0 cm electrodes carrying equal but opposite charges are spaced 2.0 mm apart with their midpoints opposite ea
serious [3.7K]

Answer:

1.77 x 10^-8 C

Explanation:

Let the surface charge density of each of the plate is σ.

A = 4 x 4 = 16 cm^2 = 16 x 10^-4 m^2

d = 2 mm

E = 2.5 x 10^6 N/C

ε0 = 8.85 × 10-12 C2/N ∙ m2

Electric filed between the plates (two oppositively charged)

E = σ / ε0

σ = ε0 x E

σ = 8.85 x 10^-12 x 2.5 x 10^6 = 22.125 x 10^-6 C/m^2

The surface charge density of each plate is ± σ / 2

So, the surface charge density on each = ± 22.125 x 10^-6 / 2

                                                                 = ± 11.0625 x 10^-6 C/m^2  

Charge on each plate = Surface charge density on each plate x area of each plate

Charge on each plate = ± 11.0625 x 10^-6  x 16 x 10^-4 = ± 1.77 x 10^-8 C

puteri [66]
That the field studys the social context in relationships, society, family, school, etc. The way we form relationships, how society affects the relationships we decide to form, how much society influences our decisions, jobs, education( more than we can imagine.)
I believe the most aggravating issue is the police bruality. The fact that the men who are suppose to be heroes, save lives through enforcing the laws, and give protection to the citizens, are instead acting as criminals themselves killing and creating a sense of danger is inexcusable and a solution needs to be made .
