In Finite Element Methods (FEM), in two-dimensional problems, we approximate solution on a domain but not the domain itself.

In Finite Element Methods (FEM), in two-dimensional problems, we approximate solution on a domain but not the domain itself. Correct Answer False

In two-dimensional problems, the finite elements are simple geometric shapes. These shapes can be used to approximate a given domain as well as the solution over it. Because of double approximation the accuracy of solution depends on both the approximations and is errors in two approximations gets multiplied.

There are two domains on your network. The DESIGN domain trusts the SALES domain. A color printer is shared in the DESIGN domain, and print permissions have been granted to the Domain Users and Domain Guests groups in the DESIGN domain. The Guest account has been enabled in the DESIGN domain. User John Y logs on using his account in the SALES domain. What must you do to allow JohnY to access the printer?
In Finite Element Methods (FEM), In two-dimensional problems, we shall have two types of errors, one due to the approximation of the solution and the other due to approximation of the domain.
A 60% spirit solution is mixed with r% spirit solution in the ratio 1 : 3 such that a s% spirit solution is obtained. When a (s/3)% spirit solution is mixed with 55% spirit solution in equal ratio, an (r/2)% spirit solution is obtained. Which of the following can be determined? (A) Value of ‘r’ (B) Value of ‘s’ (C) Volume of the 60% spirit solution mixed initially (D) If 9 liters of r% spirit solution was mixed initially, what was the volume of the s% spirit solution thus obtained?
A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y.
