Answer:

The current flowing through the 4Ω resistor is;

C. 2.0 A

Explanation:

In the given figure, we have;

The series resistors in the bridge = 8Ω, and 4Ω are in series and 20Ω and 10Ω are in series

The sum of each of the series resistors are;

R₁ = 8Ω + 4Ω = 12Ω

R₂ = 20Ω + 10Ω = 30Ω

The equivalent resistors of the series resistors, R₁ and R₂ are parallel to each other

The current flowing through the 4Ω resistor = The current in R₁ = I₁

By the current divider rule, we have;

I_1 = \dfrac{R_2}{R_1 + R_2} \cdot I

I_1 = \dfrac{30\Omega }{12 \Omega  + 30 \Omega} \times 2.8 \, A = 2.0 \, A

Therefore, I₁ = 2.0 A

The current flowing through the 4Ω resistor = I₁ = 2 A

please help me ill do anything! Collecting and Analyzing Data There are two types of observations: qualitative and quantitative.
OverLord2011 [107]
It depends on how you want to format your data table, as you can create as many columns or rows as you wish, but the important thing is, to display your quantitative data suitably and in the most simple manner. The main reason why data tables are even used, is to simplify and represent the data in an easy to interpret and access form. If your data table has two columns, then the left side would likely be the manipulated variable, or also known as the independent, and the right side would be the responding or dependent variable. To determine which is which, just look at your data and see which one is manipulated (changed) in order to make the other one "respond" or react to the changes (responding variable). In your case it seems that you do have two units, therefore two "sets" of data, so make sure you know which is which. Also, when you put it into your data table, ensure that you put your units in the top labeling row, so you won't have to rewrite (m 3) for every row of data. After that, it should be fairly easy to input your data and such into the table.

Compare the relative strengths of the nuclear force and the electric force
Serggg [28]

Answer:

To establish this relationship we must examine the potentials that these forces create. The electrical potential is described by

        Ve = k q / r

The potential for strong nuclear force is

       Vn (r) = - gs / 4pir exp (-mrc / h)

Where gs is the stacking constant and r the distance between the nucleons,

We can compare these potentials where the force is derived from the relationship

       E = -dU / dr

       F = q E
