Avery is experimenting with a simple circuit. She measures the current in the circuit three different time

The current in each experiment increases with increase in the voltage. Similarly, the association between resistance and the current in a circuit shows that increase in the resistance shows a reduction in the current, vice versa.

Ohm's Law states that the voltage across an electric conductor is directly proportional to the current(I) passing through it provided the resistant is constant.

So;

V ∝ I

V = IR

where

R = constant

The objective of this question want us to determine: How did the current change for each test provided that Avery uses a 1.5-volt battery, then she uses a 3-volt battery and lastly she uses a 9-volt battery, given that the resistance is constant through out the whole process.

In the first experiment;

1.5 = IR

In the second experiment;

3 = IR

In the third experiment;

9 = IR

Therefore, we can conclude that the current in each experiment increases with increase in the voltage. Similarly, the association between resistance and the current in a circuit shows that increase in the resistance shows a reduction in the current, vice versa.

Shortly after the Earth first formed, intense heat built up and large portions of the planet became molten. What happened to the

Drupady [299]

The Earth cooled down, forming water on vast lands while leaving others dry. oxygen and carbon from volcanoes helped create plant life under water, away from the sun's harmful UV rays. Eventually, the plants created enough oxygen to create an ozone layer around earth, making our planet sustainable for life, thus, creating life or as we can call it, one celled organisms. These cells would eventually evolve into bigger life forms, like the dinosaurs.

Any Acellus folk figure out the answer to this one??? I CANNOT for the life of me.

Olin [163]

Answer:

-0.10472 $\frac{rad}{s}$

Explanation:

Remember that any <u><em>clockwise</em></u> rotation is considered negative, and any <u><em>counterclockwise</em></u> rotation is considered positive.

The formula for period is:

$T = \dfrac{2\pi}{\omega}$

Solve for $\omega\\$ and you get:

$\omega=\dfrac{2\pi}{T}$

The period is 60 seconds so make that division and you're left with -0.10472 $\frac{rad}{s}$ or -0.10 $\frac{rad}{s}$ if significant figures apply (negative because the rotation is clockwise).

Susie operates a restaurant in the ski resort town of Asvail. She has decided to group her Other Expenses categories in terms of

nlexa [21]

Expenses including those for linen service, ice, and paper goods might fluctuate depending on demand. Other variables are constants. No change occurs to it. This is further explained below.

<h3>What is Susie's operation?</h3>

Generally, Fixed expenditures, in contrast to the more unpredictable variable costs like advertising, happen regularly at the same time each year regardless of fluctuations in revenue or other variables. It doesn't get the performance bus.

Here, we are given with table.

$\begin{tabular}{|c|c|c|}Other Expenses & Variable Expense & Fixed Expense. \\ Linen rental & $X$ & \\ piano rental & & $X$ \\ ice & $X$ & $X$ \\insurance & & $X$ \\ Pension plan & & $X$ \\Snow shoveling dees cparkinglot) & & \\Paper products & $X$ & $X$ \\ Kituen equipment & & $X$ \\ lease (mixer) & & \\Longterm debt. & & \\ Realestate tax. & & \\\end{tabular}$

In conclusion,

Linen rental, ice, and Paper Products are Variable expenses because it is based on requirement
Others are fixed by other factors. it's not affected
