When a business breaches a contract, serious consequences can occur resulting in damages and losses. An expected service or agreement that is not complied with impacts everyone involved. A breach of contract can reduce earnings while also potentially harming future profits. It also puts a company’s value at risk if it cannot satisfy demands for products or meet deadlines.

Damages involved are typically lost revenues, sales impacts involve claims for lost value, and added costs resulting from the breach. Damages estimates are made using historical information and projections to support a plaintiff’s claim

A light ray enters a rectangular block of plastic at an angle θ1 = 45.0◦ and emerges at an angle θ2 = 76.0◦ as shown. (a) Determine the index of refraction of the

Tests and quizes are worth a huge porportion of students gardes and if students are constantly doing bad their grades are going to lower drastically. RUP helps students and provides all the resources for students to go far in life its just up to them to decide whether to take advantage of these amazing resources that are provided. The review packet was optional, I chose to do it and the results on my previous test were really good.

As I mentioned in Unit 2, I have always leaned more towards the delivery skills as opposed to the discovery skills. I attribute this to the structured environment of the military. Junior ranks in the military are not encouraged to be innovative, they are rewarded for their ability to delivery which results in promotion. However, as individuals gain rank, innovation begins to play a role in continued progression. In my current rank as a Chief Warrant Officer and working as a Cyber Operations Technician I have learned to apply the discovery skills mentioned in the The Innovator’s DNA, specifically networking, observation and experimenting.

My group has summary about this question of football in unit 7.  We think that football can less violent by increase more law in sport. Football can interest to people, advertiser, media and sponsor. Otherwise you can play football with friends any time. In other word football can unite people together. For example one football club have many nationality soccer players and form many competition around the world to challenge.

My first procedure that I completed was the filtration. When I mixed the lead (II) nitrate and the sodium iodide together, I got a bright yellow liquid that turned out to be lead (II) iodide. I believe I did this part of the procedure correct because the color was not too pale and I did not use too much lead (II) nitrate or sodium iodide. I used the correct amount to get the results that were listed on the laboratory, In procedure D, Glassworking, cutting the glass came out great. I followed all safety procedures and it snapped perfectly. Although, I could have fire polished the cut glass a little bit more but could not due to time constraints. A problem I could have had during this procedure is not having the Bunsen Burner flame too low where

The purpose of this experiment was to observe the different kind of crystal package arrangements that each material experienced after an impact load. For this reason, a varying range of temperatures were used during the experiment. As a result, comparing the effects that temperatures had on the types of fractures each material experimented.

The process to produce plywood begins with obtaining the raw materials. The wood is then conditioned with water. The wood has to be sized and stripped of bark make it easier to handle. Then it is placed on a machine cuts it into thin sheets. Drying methods are used to add veneer. The sheets are sorted into four types of pieces: face, cross bands, core and back. Each wood layer is perpendicular to the fiber of the previous layer to add strength to the plywood sheet. The layers are glued and then pressed together by a cold press, which helps flatten the plywood sheets. The hot press afterwards is used to cure the wood. The thickness of the sheet depends on the use of the plywood. Finally, the plywood undergoes strict safety and quality inspections, then it is taken to be delivered. This video is a great example of how manufacturers obtain raw materials, produce a standardized product, and then deliver it to the customer because of their simple, yet layered, manufacturing process.

In order to understand the obsidian hydration dating method, a model that can demonstrate the process of glass hydration under a certain range of environmental conditions is needed. To implement this, the nature of the concerned materials i.e. glass and water should be adequately

Sodium Carbonate (Na2CO3) also known as soda ash is mixed with sand to produce a product of 75% silica (SiO2) and 25% sodium oxide (Na2O). This mixture will melt and fuse at a much lower temperature of 800°C. Unfortunately, the glass produced with this composition is water-soluble which is also known as water glass. This is not suitable for glass bottle since it need to contain water so, to stabilise the glass, other chemical substance is mixed into the composition such as calcium oxide (CaO) and magnesium oxide (MgO). The chemical mixtures are obtained by the addition of lime stone which produce a pure and inert glass.
