Describe your ecological footprint. What do the results mean? What are some things
bixtya [17]

The ecological footprint finds the person demand on natural demand.

<h3>What is ecological footprint?</h3>

The ecological footprint is the method promoted by the Global Footprint Network to find human demand on natural capital. The quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system.

Some things which could do to reduce your footprint is Reduce Your Use of Single-Use, Disposable Plastics, Switch to Renewable Energy, Eat Less Meat, Reduce your Waste, Recycle Responsibly, Drive Less, Reduce Your Water Use, Support Local.

Thus, the ecological footprint is to find person demand on natural demand.

Compare and contrast electric potential energy and electric potential difference? Explain.
forsale [732]

Answer:

<u><em>Electric Potential Energy:</em></u>

The energy that is needed to move a charge against an electric firld is called Electric Potential Energy

<u><em>Electric Potential Difference:</em></u>

The amount of work done in carrying a unit charge from one point to an other in an electric field is called Electric Potential Difference.

<u><em>Relation:</em></u>

Relation between Electric potential and electrical potential energy is given by

\delta V=\frac{PE}{q}

Here PE represents Electric potential energy

and \delta V is Electric potential difference

it means electric potential difference is the difference in electric potential energy divided by the charge.

An aircraft maintenance technician walks past a tall hangar door that acts like a single slit for sound entering the hangar. Out
Sphinxa [80]

Answer:

The first minimum would be observed at 41.57°

Explanation:

v = 340m/s = speed of sound

f = 610Hz

d = 0.840m

λ = ?

Mλ = wsinθ

m = mth order minima

λ = wavelength incident on the single slit

θ = angular position of the mth minima

But, λ = v / f

λ = 340 / 610 = 0.557m

θ = sin⁻(mλ/d)

θ = sin⁻ [(1 * 0.557) / 0.840]

θ = sin⁻ 0.6635

θ = 41.57°

The first minimum would be observed at 41.57°
