<span>The answer to the question is atmosphere. The atmosphere is the spherical layer of Earth that contains a mixture of gases that are necessary for life on Earth. The atmosphere helps insulate the Earth's temperature as well as getting out some of the harmful things from outer space like filtering out harmful UV radiation from the Sun and burning up meteorites.</span>

In a circuit, two resistors of 100 Ω and 80 Ω are connected in parallel. The parallel group is then connected in series with a 1

nordsb [41]

Answer:

Total Resistance = $\frac{1300}{9}$ Ω (or 144.44 Ω)

Step-by-step explanation:

If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:

$\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}$

If 2 resistors with resistance x and y and connected in series, their total resistance would be:

Total = x + y

<em>Now, the first part, 100 and 80 are in parallel, so according to formula it would be:</em>

<em> $\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}\\\frac{1}{Total}=\frac{1}{100}+\frac{1}{80}\\\frac{1}{Total}=\frac{9}{400}\\Total = \frac{400}{9}$ </em>

<em />

<em>Now, this is connected in series with 100, so the grand total would be:</em>

<em>Total Resistance of Circuit = $\frac{400}{9}+100=\frac{1300}{9}$ </em>

<em />

This is the total resistance of the circuit.
