Answer:
A stainless steel containing 18wt% of Chromium are magnetic and often used for knifes and blade because of the lattice structure of the stainless steel. The stainless steel are hard, due to the molecules in chromium are smaller and which makes them look like the molecules in wrought iron.
A stainless steel which contains 18wt%Cr and 8wt%Ni are not magnetic because of the lattice structure of the metal stainless steel. This steel are not very hard, due to the molecules of larger and looks like the molecules of a cast iron.
Tool steel that are mixed with small stable carbide retains their temperature when heated above the the normal temperature that can melt steel, because the steel has been mixed with carbide. Carbide is rich in carbon, and has a very high temperature which makes it able to retain heat. When carbides mixes with metal, it boiling point increase to a very high temperature.
The teaspoon that is made up of a single piece of stainless steel that contains only Nickel is made of two parts, the handle and the bowl. The bowl part are not magnetic because it is curved and very smooth, which changes the lattice structure of that part to become FCC. The handle part are magnetic because they are plain and are not very smooth, which makes the lattice structure to be BCC.
Answer:
It can change negative attitudes to positive ones
Explanation:
When an advert is done to target audience, some of the consumers may have developed a negative attitude towards the product or services before. However, when an advert is properly conveyed, there are chances that the consumers may change to have a positive attitude towards the advertised product or service. In conclusion, advertising can affect attitudes but cannot alter values or force people to do things they do not want to do or believe are wrong.
The voltage supplied in the communication room to the light fixtures can be 120 volts or 277 volts respectively.
Options B and C are the correct answers.
<h3>What is voltage?</h3>
Voltage is the electric force that makes the charges move which creates an electric current.
The light fixtures are the component of light that is being attached to the wall or a ceiling that holds any kind of lighting element. For instance, the holder of a bulb in which it is fixed is treated as a light fixture. The general voltage produces by a light fixture is 120 volts but preferable should be at 277 volts.
Therefore, all the volts except which is mentioned in options A and D cannot correspond to the voltage of light fixtures.

Answer:
It value is range varies from 0.45 for Soth Asia, 1.1 for middle east and North America and 2.2 kg/capita/day for OECD countries.
Explanation:
Solid waste generation is about in the range of 63 million tonnes per year in the North Africa and Middle East . Per capita waste generation is 0.15 to 5.7 kilogram in a day for 1 person, and the average is of about 1.1 kg/capita/day.
Its about 571 million tonnes solid waste in a year is generated by The OECD countries . The value of per capita is ranging about 1.2 to 3.7 kg in a day for a person with the average value of about 2.2 kg per capita per day
Its about 70 million tonnes of solid waste in a year is generated by The South Asian countries . The value of per capita is ranging from 0.12 to 5.1 kg in a day for a person with the average value of about 0.45 kg/capita/day
