Topic Selection Microsoft recently unveiled its prototype‚ Surface‚ their version of a tablet or alternative device to a personal computer. It is questionable how Microsoft‚ a known software company‚ will be able to manufacture and sell a tablet device that is a contender in the marketplace against devices such as the iPad. Thesis: It is critical that Microsoft produce a device that overcomes the limitations of its competitors and adds features that set it apart‚ in order to define itself in

have the same volume as the original model. Q1. Use a piece of A4 paper to make a box with a length of 10cm and a width of 3cm. Then find the volume of the box and the total surface area of the paper used to make the box. T.S.A: 5 rectangles and 4 squares 5 x L x W + 4W = 5 x 10 x 3 + 4 x 9 = 186cm Volume: 5 rectangles and 4 squares L x W x H = 10 x 3 x 3 = 90cm Q2. Make another box with the same general shape‚ but chose a different length and width. Then find the volume of the box and

Achievement Standard 91106 (2.9) Log number: 4 Title: The Heat Text type: Film Director: Paul Feig The film ‘The Heat’ is a film about a very formal but cocky FBI agent who is paired with a really aggressive Boston cop to take down a ruthless drug lord. The FBI agent‚ Sarah Ashburn‚ only agreed to take on this case to get a promotion. The Boston cop‚ Mullins‚ was chosen to do this case because she knew the town better than anyone else did. Sarah Ashburn and Mullins did not like each other

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

only to Van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion‚ along with adhesion (attraction between unlike molecules)‚ helps explain phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom of the flask ‚ and if enough is placed in the flask

in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine the heat transfer rate‚ the

Mechanisms of Heat Transfer Prepared by: Ms. Ana Antoniette C. Illahi 1 Conduction • conduction (or heat conduction) is the transfer of thermal energy between regions of matter due to a temperature gradient. Heat spontaneously flows from a region of higher temperature to a region of lower temperature‚ and reduces temperature differences over time‚ approaching thermal equilibrium.
