Consider heat conduction through the wall of a pipe with inside wall temperature of 200oc and outside temperature of 80oc. the wall is 0.05 m thick with inside radius r0 of 0.05 m and outer radius rn of 0.1 m. thermal conductivity of the wall is 1w/moc. the differential equation which describes the radial temperature distribution is dt dr + r d 2t dr 2 = 0 solving the above equation with finite difference method on n equally-spaced node points along the radial direction, together with application of temperature boundary conditions at inner and outer wall yields the following system of equations: t1 = 200 ri ∆r 2 − 1 ∆r ti−1 − 2ri ∆r 2 ti + ri ∆r 2 + 1 ∆r ti+1 = 0 i = 2, 3, n − 1 tn = 80 ri is radial position of the nodes and can be written as ri = r0 + ∆r (i − 1) i = 1, 2, n radial spacing between the nodes ∆r can be computed as: ∆r = rn − r0 n − 1 (a) solve the temperature values t using thomas method with number of nodes n = 11. remember that radius ri is not constant. provide the m-files. (b) plot the temperature profiles, i. e. t versus ri . make sure the axis are properly labeled.

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.

explanation:

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

the answer is barium and copper bromide
