What are some of the regulations about cell phone waste?
In general, companies take part in the responsibility of taking back the e-waste resulted from their products.
Are the regulations the same everywhere, which countries have different regulations?
In 2005, two important directives were published in the European Union. The first stipulates that: 1) all manufacturers selling electrical and electronic equipment in and to EU countries label the equipment to inform customers that it must be recycled and 2) make sure that their products are properly disposed of or recycled after the life cycle. The second requires manufacturers to eliminate or minimize the use of lead, mercury, hexavalent chromium, cadmium, polychrome and diphelin biphenyl ethers in electrical and electronic equipment sold in the EU after 1 July 2006.
New technology to reduce waste?
Companies are trying to reduce the amount of resources needed in order to create their products. One alternative is the modular smarthphones, which aims to reduce the amount of e-waste of the phone by only upgrading a few elements of hardware.

A 5 kg block
is pulled across a table by a horizontal force of 4O N with a frictional force ot 8N pOsing the motion. Calculate the acceleration of the oject. 12 An ahia iddt
Answer:
By Newton's 2nd law, m*a=sum_of_forces where m is the mass and a the acceleration. Here there are two forces in opposed directions.
Thus 5*a=40-8=32 therefore a=32/5=6.4m^s/2
Write the difference between isomerism and allotropy with one example each.
Answer:
hope it helps ..
Explanation:
Allotropes can be defined as different types of compounds made out of the same single element but in different chemical formulas and different arrangements. Isomers can be defined as the chemical compounds that have a similar molecular formula but with different structural formulae. Graphite and Diamond.

Create a sort of infomercial featuring a solution you created or designed.
Say a few statements about it.
please help
Answer:
Informercials, like the class Shamwow Informercial are an example of how structure and technique can have a huge effect on how a user or prospect is driven towards taking a specific action like clicking a buy button.
Informercials follow a specific structure that any small business can use to drive action but few businesses ever consider using it when they pitch their product or service. In this post, we'll describe the structure and give you examples of how you can use it in your business.
The question above wants to test your ability to create an infomercial using your creativity. For that reason, I can't create an infomercial for you, but I'll show you how to create one.
First, you need to know that an infomercial is an advertisement made to be played on television, usually associated with sales, but can be used to present information.
Based on this, you should create your newsletter as follows:
Establish the element that your infomercial wants to present.Show what are the issues related to this element.Show the solutions you want to present to these problems.Show how these solutions are truthful and reliable.In the image below, you can see a tutorial on how to make an infomercial.
