Based on the length of the Ethernet cable and the mass, the tension in the cable can be found to be 80 N.
<h3>How much tension is in the cable?</h3>
The tension in the cable can be found as:
= 4 x mass x length x frequency
Solving for the frequency is:
= 1 / (0.800 / 4)
= 1 / 0.20
= 5.0 Hz
The tension is therefore:
= 4 x 0.20 x 4.00 x 5
= 80N

Answer:
No image will be observed.
Explanation:
Images that are created by mirrors are virtual images. This virtual image can only be seen by an observer. In this case, an infinite number of images or no image will be created here as both will be reflecting their own images. Light will continuously bounce back and forth reflecting the same image.

where 
=charge density
Most fish fossils are: <u>D. from sharks, eels, and stingrays</u>.
<u>Explanation</u>:
A fossil is a preserved part or trace of a living being in the geological age. Animals, fish, bones and shells are some of the fossils. Fish fossils are the dead fish that are found under the river bed or ocean.
The dead animals in the water bodies are buried under the mud for long period of time. The soft tissues of the animals are decomposed leaving the dry bones.
There are five different types of fossils. They are
i) Body fossils
ii) Molds and casts
iii) Petrification fossils
iv) Footprints and trackways
v) Coprolites
One of the common fossils is shark tooth. The tooth of the sharks is shed continuously. The fish fossils are found at the bottom of the ocean, lake and pond deposits.
