Answer:

A.) Energy Conversion

D.) Energy Transformation

[ Correct on Edgenuity ]

Explanation:

These other listed options are incorrect because :

(bolded sentences are the reason why)

Incorrect : B.) Energy conservation  

Energy conservation is the <u>prevention</u> of the wasteful use of energy, especially in order to ensure its continuing availability. This does not describe change; it talks about prevention.

Incorrect : C.) Energy correlation

The energy correlation is a <u>measure</u> of how much the <u>movement</u> of one electron is influenced by the presence of all other electrons. This only describes the measure of movement and not the physical form of energy change.

Incorrect : E.) Energy transference

Energy transference is the <u>conversion</u> of one form of energy into another, or the movement of energy from one place to another. It has the correct definition but this is the incorrect term that's being used. Instead, you would have used energy transformation.

*[ A and B are correct, I recieved 100% on the quiz on Edgenuity ]*

Hope this helped! Have a wonderful day! :)

50 POINTS AND BRAINLEIST A Ferris wheel has a mechanical advantage of ___________________________ one and the trade off is that
kiruha [24]

Answer:

C.) The same as one

Explanation:

Because the Ferris wheel has two bars at the side that keep it in place so it doesn't roll away. The Ferris wheel only moves in one place. If the ferris wheel did roll then you would have a greater than one. If it did roll it would be dangerous.

A copper wire has a diameter of 2.097 mm. what magnitude current flows when the drift velocity is 1.54 mm/s? take the density of
frozen [14]

By using drift velocity of the electron, the current flow is 7.20 ampere.

We need to know about drift velocity of electrons to solve this problem. The drift velocity can be determined as

v = I / (n . A . q)

where v is drift velocity, I is current, n is atom number density, A is surface area and q is the charge.

From the question above, we know that

d = 2.097 mm

r = (0.002097 / 2) m

v = 1.54 mm/s = 0.00154 m/s

ρ = 8.92 x 10³ kg/m³

q = e = 1.6 x 10¯¹⁹C

Find the atom density

n = Na x ρ / Mr

where Na is Avogadro's number (6.022 x 10²³), Mr is the atomic weight of copper (63.5 g/mol = 0.635 kg/mol).

n = 6.022 x 10²³ x 8.92 x 10³ / 0.635

n = 8.46 x 10²⁷ /m³

Find the current flows

v = I / (n . A . q)

0.00154 = I / (8.46 x 10²⁷ . πr² . 1.6 x 10¯¹⁹)

0.00154 = I / (8.46 x 10²⁷ . π(0.002097 / 2)² . 1.6 x 10¯¹⁹)

I = 7.20 ampere
