Answer:

6 + (d * 2)

Step-by-step explanation:

You are adding 6 to the equation after the amount d times 2. In that case, a parentheses is required to round up d * 2.

What is the total resistance of a parallel circuit that has two loads? Load one has a resistance of 10 ohms. Load two has a resi

Romashka-Z-Leto [24]

Answer:

The total resistance is $7.0588\Omega$

Step-by-step explanation:

Attached please find the circuit diagram. The circuit is composed by a voltage source and two resistors connected in parallel: $R_1=10\Omega$ and $R_2=24\Omega$ .

First step: find the total current

For finding the current that the voltage source can provide, you must find the current consumed by each load and then add both. To do that, take first into account that the voltage is the same for both resistors ( $R_1$ and $R_2$ ).

$I_{R_1}=\frac{V_S}{R_1}$
$I_{R_2}=\frac{V_S}{R_2}$

The total current is:

$I_{TOTAL}=I_{R_1}+I_{R_2}=\frac{V_S}{R_1}+\frac{V_S}{R_2}=\frac{R_2\cdot V_S+R_1\cdot V_S}{R_1\cdot R_2}$

$I_{TOTAL}=V_S\cdot \frac{R_1+R_2}{R_1\cdot R_2}$

Now, the total resistance ( $R_{TOTAL}$ ) would be the voltage divided by the total current:

$R_{TOTAL}=\frac{V_S}{I_{TOTAL}}$

If you replace $I_{TOTAL}$ by the expression obtained previously, the total resistance would be:

$R_{TOTAL}=\frac{V_S}{V_S\cdot \frac{R_1+R_2}{R_1\cdot R_2}}$

After simplifying the terms you should get:

$R_{TOTAL}=\frac{R_1\cdot R_2}{R_1 + R_2}}$

Now, you must replace the values of the resistors:

$R_{TOTAL}=\frac{(10\Omega )\cdot (24\Omega)}{10\Omega + 24\Omega}}=\frac{120}{17}\Omega=7.0588\Omega$

Thus, the total resistance is $7.0588\Omega$

Leokris [45]

Answer:

c. PROPOSITION ONE is false and PROPOSITION TWO is true

Step-by-step explanation:

In this question, we have that:

pvalue of 0.058

Significance level of 0.05

The pvalue is larger than the significance level, which means that there is no statistically significant association(Propostion One is false), and the null hypothesis is not rejected, that is, it is proved, so Proposition Two is true.

This means that the correct answer is given by option C.
