Wedding Speech Delivered by the Bride :: Wedding Toasts Roasts Speeches

Wedding Speech Delivered by the Bride Families and friends. This has been a terrific day for Bob and I and we are both thrilled you could all be here. I wanted to say a few words in response to my Dad and thank a few people for all their support. I have spent a lot of time thinking about how to make these thanks – its amazing how much advice and how many books there are out there for Groom and Best Man’s speeches but there is not a lot out there to help the bride. So having failed to find any sensible advice in print, I thought I would ask around to the family and friends for some advice on what to say this evening. I didn’t get much advice about the speech but they gave me some useful snippets to use. Sarah found out that Bob and I will share our wedding day and anniversary with a very famous Royal – 2 very famous Royals in fact – the Queen obviously as I believe she is having some sort of celebration herself this weekend. The other Royal is the late King Edward who abdicated to be mar ried to the love of his life – Mrs Simpson. Now I expect that Bob and I in time will be more like â€Å"The Simpsons† than Edward and Mrs but I trust we can be as happy as that couple were. I have some thanks to make. Firstly Paula – thanks for the â€Å"hairdo† and busting a gut to get here on time to have a trial run. Ben – thanks for taking photos for our guest book and thank you all for posing and signing it. Sarah – you made your dress, you looked after me on my hen night (I’ll forgive you for buying me that Tia Maria and get you back some time). You have been the perfect Best Woman and a great friend for may years now. You have always been around for me through thick and thin and it was a privilege to be your bridesmaid last year. I have to thank your new husband Ian too for marrying you – it has been fantastic fun planning weddings together and thanks for all your top tips and ideas – many of which you can see we have stolen! Simon – perhaps I should reserve my thanks to you until after your Best Man’s speech! Thanks for being such a good mate to Bob for so long and for brushing up so well today.

Inertia lab report Essay

A Rotational motion experiment is the simplest method of finding the Moment of Inertia. Minimum equipment is required to perform this experiment. For the purposes of increasing the accuracy of the results, the procedure should be repeated three times, making our conclusion more reliable. While load is moving downwards it’s potential energy converts to kinetic. Load is accelerating because weight(Fg=mg) of the load is bigger than tension on a string so load is not in equilibrium and by Newton’s Second Law (F=ma) resultant force creates an acceleration. Resultant force can be calculated by the equation S=0. 5at2+ut to find acceleration and F=ma. String rotates the spindle which rotates the disc by creating a torque(T=Fr). Torque accelerates the disc and it can be found by ? = . To find moment of inertia now T=I? equation is used. 1 Method and observation: Apparatus: 3 different size discs, spindle, ruler, set of weights, stopwatch, stand. Disc is attached to one end of the spindle and string with load is attached to the other end. Disc’s weight, diameter and radius are required to be measured before experiment. Length of the string (L), number of loops on the spindle (n) and horizontal distance of loops (H) were measured before experiment. Using equation below r is found. = 2 Spindle Disc String Stopwatch Weights Stand After setting all the equipment up the experiment starts. The string is then wrapped around the spindle. Time was measured for load pass the distance of length of the string. To plot graph one over time2 is required to be calculated. 4 different masses of the load are used in experiment is repeated 3 times every time mass is changed to make reduce random error. After finishing all the experiments on one of the discs other disc is placed and experiment repeats. When all the experiments are done and measurements are recorded mass against one over time2 is plotted using results. 3 graphs are going to be plotted for each disc. Gradient of the graph is constant k which we could use to find I using formulae below. When observed the string with vibrating and load was moving a little which can cause some systematic error. While spindle is spinning there is some friction which is neglected and the disc is vibrating while it is spinning which also cause some systematic error. = ? 2 2 Results MEASUREMENTS ON THE SPINDLE: MEASUREMENTS ON THE DISCS n= 8 L= 0. 26m DISC 1 (small) DISC 2 (medium) DISC 3 (large) Weight (kg) 0. 314 0. 490 Diameter (m) Radius (m) 0. 1 0. 127 0. 05 0. 0635 0. 696 0. 152 0. 076 H= 0. 026m r= 5. 14Ãâ€"10-3 DISC 1 Weight (kg) Time (s) Average Time (s) 1/t?

As we can see the gradient on the graphs are larger at larger discs. From theoretical values which it can be concluded that experiment was right. More time is taken to pass that distance for larger discs because the moment of inertia is bigger so it torque is required to accelerate the disc. However there were some random and systematic errors. One of the most effecting random errors is the human reaction error. It could be decreased by using light gate instead of stop watch. Using more accurate equipment for taking measurements of discs and spindle would decrease the error. Masses of the loads are not exact so more accurate loads would decrease the error. Conclusion Larger and heavier discs have larger moment of inertia so they require more torque to be accelerated.

Beowulf The Canonization of Anglo-Saxon Literature into...

The cover of the November, 1975 comic book Beowulf: Dragon Slayer features a red-haired, horn-helmeted Beowulf swinging a large broadsword at a purple-caped villain also bearing two razor-sharp swords. As Beowulf rears up on his steed, a bikini clad woman, cloth slightly aside to reveal the shadow of a buttock is drawn falling, face filled with terror. In the background, a rising full moon and silhouetted gothic castle keenly set an atmosphere of dread and foreboding. Above the emboldened title of the comic book reads in smaller letters, Beowulf: First and Greatest Hero of Them All! Text in the bottom-left corner gives the juicy hook for this edition: Beowulf Meets Dracula. Despite over eight hundred years of literary†¦show more content†¦Dont tell me D.C. is doing Classics Illustrated? No. NOT Classic Illustrated, but REAL LIVE action and adventure stories! BEOWULF is the oldest surviving piece of English literature. Its an epic poem in the vein of The Odyssey and T he Illiad, author unknown. It has been hailed as one of the masterpieces of the English language. Its EXCITING! (2). Despite eighteen preceding pages featuring Beowulf fighting monsters and saving beautiful women, Uslan assumes that the target audience of the comic book considers Anglo-Saxon subject matter boring and worse, educational. The excessive use of punctuation, ?!?, following BEOWULF may seem quaint and immature to modern readers but it is worth consideration that Uslan is aiming his book at contemporary adolescent boys. The over punctuation suggests shock and disappointment, a sense that D.C., the producers of such wiz-bang fare as Batman and Superman could stoop so low as to make comics that one would read for junior high school English class. The dismay puts Uslan on the side of the reader - his emphatic punctuation endears him to the target audience as one of their own. Therefore he establishes a middle ground of authority in which to defend his use of Anglo-Saxon material in comic book form. Uslans defense of Beowulf within the space of the mainstream is that it features REAL LIVE action and adventure stories. Theres a suggestion that academic
