Answer:
Rubber:Covalent bonding
Barium sulfide:ionic bonding
Solid xenon: Van daar Waal bond.
Bronze:Metallic bond
Nylon:Covalent bonding
Aluminum phosphate: mixture of ionic and covalent bond
Explanation:
Rubber is mainly composed of isoprene which is predominantly covalent bond
Barium sulphide is predominantly ionic bonding
Is xenon is inert its bond is van daar Waal
Bronze is an alloy of metal usually held by metallic boding
Nylon:covalent bonding
Aluminium phosphate have a mixture of covalent and ionic bond

a social news website is an internet website that features user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the slashdot and fark websites, administrators decide which articles are selected for the front page. on reddit and digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a social networking function, in that users can set up a user profile and follow other users' online activity on the website
Answer:
a) omax=125 MPa
omin=75 MPa
b) Temperature = 1289.6°F
Explanation:
a) The mean stress is:
omax+omin=200 MPa
stress amplitude=50 MPa
omax-omin=50MPa
2omax=250 MPa
omax=125 MPa
omin=75 MPa
b) For copper, the creep is important at 0.65 of the melting point, thus:
Temperature = 0.65*1984°F=1289.6°F
