<h3><u>Answer;</u></h3>

D. Velocity

<h3><u>Explanation;</u></h3>

<u>Velocity is the rate of change of displacement. It is given by dividing the displacement covered by the time taken.</u>
That is; Velocity = Displacement/time
Therefore<em><u> if two individuals took the same time to cover the same distance, then it means both will have the same velocity.</u></em>

Why are different colors used to represent the floor of the ocean?

ZanzabumX [31]

The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean. ... In coastal areas, runoff from rivers, resuspension of sand and silt from the bottom by tides, waves and storms and a number of other substances can change the color of the near-shore waters.

3. A wye-connected load has a voltage of 480 V applied to it. What is the voltage dropped across each phase?

ZanzabumX [31]

Answer:

$E_s = 277.13V$

Explanation:

Given

$Load\ Voltage = 480V$

Required

Determine the voltage dropped in each stage.

The relation between the load voltage and the voltage dropped in each stage is

$E_l = E_s * \sqrt3$

Where

$E_l = 480$

So, we have:

$480 = E_s * \sqrt3$

Solve for $E_s$

$E_s = \frac{480}{\sqrt3}$

$E_s = \frac{480}{1.73205080757}$

$E_s = 277.128129211$

$E_s = 277.13V$

<em>Hence;</em>

<em>The voltage dropped at each phase is approximately 277.13V</em>

The distance from the Earth to the Sun is known as an astronomical unit (AU). This distance is also equal to 1.496e+011 m. Neptu

Lerok [7]

Answer:

The distance from the Sun to Neptune is 29,41 AU.

Explanation:

We know, from the sentence, that the orbit of Neptune has an average diameter around 8.80*10⁹km.

Now, we can calculate the radius of this orbit, which is equivalent to the distance from thsi planet to the Sun. Let's recall tha the radius is the half of the diameter.

$R=\frac{8.80\cdot 10^{9}}{2}=4.4\cdot 10^{9}km=4.4\cdot 10^{12}m$

Ok, we know that 1.496*10¹¹m is an AU, therefore we have:

$4.4\cdot 10^{12}m\cdot \frac{1 AU}{1.496\cdot 10^{11}}=29,41 AU$

Finally, the distance R is 29,41 AU.

I hope it helps you! :)
