<h2>Answer:</h2>

The scientist is <u>E. Thomson </u>.

<h2>Explanation:</h2>

In the late nineteenth century, physicist J.J. Thomson started trying different things with cathode beam tubes. Cathode beam cylinders are fixed glass tubes from which the greater part of the air has been emptied. A high voltage is applied crosswise over two terminals toward one side of the cylinder, which makes a light emission stream from the cathode (the contrarily charged anode) to the anode (the emphatically charged cathode).

The cylinders are called cathode beam tubes on the grounds that the molecule bars or “cathode beam” begins at the cathode. The beam can be distinguished by painting a material known as phosphors onto the most distant finish of the cylinder past the anode. The phosphors sparkles, or produces light, when affected by the cathode beam.

How do the two desalination processes differ from the atmospheric water generator in terms of where the processes can be used?
-Dominant- [34]

Water Desalination Processes. Water desalination processes separate dissolved salts and other minerals from water. Feedwater sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor),...

a certain piece of copper wire is determined to have a mass of 2.0 0g per meter how many centimeters of the wire would be needed
harina [27]

The given question tells you that a certain piece of wire has a mass  = 2.0 g per meter

That means that if you consider a piece of wire that is 1 m in length, its mass will be equal to  2.00 g .

According to question,

Now, you know that

1 m = 100 cm

Mass of  2.00 g  of copper will correspond to a wire that is a 100 cm long.

This implies that  0.28 gof copper will correspond to a wire that is

0.28 g * 100 cm /  2.0 g = 14 cm long

Hence, 14 cm of the wire would be needed to provide 0.28 g of copper.

Properties of Copper :

High conductivity and ductility.

Non magnetic.
