The two diagrams illustrates the design for a wave-energy machine and its location.

The first image is of the design of the wave-energy machine and how it works. The machine mainly consists of three main parts the turbine, the chambers and the electricity generator. The machine is designed in such a way that when waves enters through the opening at the bottom the water level increases and pushes the air above which consequently turns the turbine and as a reuslt electricity is generated. The air then flows out through the other opening at the top. There are also two sections in the machine to maintain the air flow which helps in pushing the water back.

The second figure explains how diffrent locations affects the output and the installation cost of the machine. There are two options for the installation, the first being near the shore, and the other being in deep waters. The one at higher ground level has low installation cost and low output as it will receives smaller waves. The one in deep waters will not only have higher output as it will receive larger waves but also will be expensive for installation.

Internet has made everything easier these days, you are just one search away from the thing you want. One of the benefits of internet is online shopping. One can buy anything from a pencil to a vehicle online. Online shopping being so easy it is becoming more and more popular.

There are numerous advantage of buying things on the internet. First of all it is easily accessible, you can book tickets or buy groceries sitting on your couch, at any time of the day, without having to stand in long lines. Secondly, you get a variety of products that you can compare and choose from. Finally, the biggest advantage is discounts, online sale and special offers that the online sopping platforms provide.

In my opinion internet has made shopping easier and faster but some people might disagree with me as there are disadvantages of it too. My father belives before buying any product one should research about it, test it and compare the prices in different stores, all this is not possible while shopping online and for these reasons he prefers to shop in stores. Not only you are unable see the product beforehand but also returning a deffective one is a hindering process.

My cousin bought some clothes online and after receiveing the product she felt they were not good so she tried to return them, although the clothes where returned back she did not get any refund. Furthermore, after contacting the seller and complaining to the buying platform there was no response.

Every coin has two sides, as far as I am concerned the disadvantages are negligible and they are outweighed buy the advantages.
