Sholpan [36]3 years ago

Answer:

SO4

Explanation:

I'm not sure if you're asking for more than one answer but S04 is one of them, you can search it up if you don't believe me

ion with the subscript of the atoms in a polyatomic ion. There is only ONE Cu and ONE S04, so get the charge for the Cu based on the S04. The formula is S04 , and there is only ONE S04 2, so Cu's charge here must be +2 for the compound to have an overall charge of zero. = copper (Il) ion S04 = sulfate ion then CuS04 = copper (Il) sulfate

A monument has a height of 348 ft, 8 in. Express this height in meters. Answer in units of m.
tensa zangetsu [6.8K]

Answer:

The height of mountain in meter will be 106.2732 m

Explanation:

We have given height of mountain = 348 ft,8 in

We know that 1 feet = 0.3048 meter

So 348 feet =348\times 0.3048=106.07meter

And we know that 1 inch = 0.0254 meter

So 8 inch 8\times 0.0254=0.2032m

So the total height of mountain in meter = 106.07+0.2032 = 106.2732 m

The height of mountain in meter will be 106.2732 m

How do solar panels create electricity
xenn [34]

Answer:

They create electricity from the sun's  rays

Explanation:

By the use of "solar cells" or "solar panel", you can trap solar energy in silicon/germanium rods, then you can convert in into electricity too. Solar powered panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

Christian made some pancakes she's so 3/5 of them in the morning and 1/4 of the remainder in the afternoon is she had 300 pancak
DiKsa [7]

Christian made 1000 pancakes.

Explanation:

Let us represent the total amount of Pancake made by Christian as = K

    From the problem;

 Christian ate \frac{3}{5} of the pancake in the morning =  \frac{3}{5}  * K =  \frac{3}{5} K

We know that Christian cannot eat her pancake and at the same time have it, the  remaining pancake will then be:

        total amount of cake - fraction eaten

Remainder = K -  \frac{3}{5} K=  \frac{2}{5} K

   

In the afternoon, we know that she ate 1/4 of the remaining cake:

        \frac{1}{5} K*  \frac{2}{5} K = \frac{1}{10} K

 The remaining cake in the afternoon will be:

    Total amount of cake remaining from morning - amount eaten in the afternoon

    =    \frac{2}{5} K -  \frac{1}{10} K

    =    \frac{3}{10} K

The fraction of the cake remaining in the afternoon is  \frac{3}{10} K

Since she had 300cakes left in the afternoon, then :

            \frac{3}{10} K= 300

                    K = 1000 pancakes

Therefore Christian made 1000 pancakes.

What is the velocity of a wave with a wavelength of 9 meters and a period of 0.006
Ipatiy [6.2K]

Answer: 1,500m/s

Explanation:

Relationship existing between velocity of a wave (v), wavelength(¶) and frequency(f) is

v = f¶... (1)

Since Frequency (f) is the reciprocal of the period (T);

Frequency = 1/Period i.e F = 1/T... (2)

Substituting equation 2 into 1 we have;

v = 1/T × ¶

v = ¶/T

Given wavelength ¶ = 9m

Period T = 0.006s

v = 9/0.006

v = 1,500m/s

The velocity of the wave will be 1,500m/s

dybincka [34]

To choose the correct box plot, verify each of the options and make sure all the values in the plot match the values provided.

<h3>How to identify the median?</h3>

In a box plot, this value is represented by a vertical line located in the middle of the graph.

<h3>How to identify the maximum and the minimum?</h3>

The maximum is the value located on the farthest right, while the minimum is located on the farthest left.

<h3>How to identify the quartiles?</h3>

Divide the graph into 4 and analyze how much each quartile represents.
