Problem 57P

A Thermodynamic Process ?in ?an Insect?. The African bombardier beetle (?Stenaptinus insignis?) can emit a jet of defensive spray from the movble tip of its abdomen (Fig. P19.57). The beetle’s body has reservoirs of two different chemicals; when the beetle is disturbed, these chemicals are combined in a reaction chamber, producing a compound that is warmed from 20°C to 100°C by the heat of reaction. The high pressure produced allows the compound to be sprayed out at speeds up to 19 m/s (68 km/h), scaring away predators of all kinds. (The beetle shown in the figure is 2 cm long.) Calculate the heat of reaction of the two chemicals (in J/kg). Assume that the specific heat of the two chemicals and the spray is the same as that of water, 4.19 × 103 J/kg · K, and that the initial temperature of the chemicals is 20°C. Figure P19.57

Key words Page 2 of 4 Chapter 2 _____ exist when consumers incur an expense to move from one product or service to another. Switching costs Operational effectiveness refers to: performing similar tasks better than rivals Operational effectiveness is usually not enough to yield sustainable competitive advantage because technology can be easily duplicated. Dell, previously the world's number one PC manufacturer, has seen its market share shrink because of rivals copying its value chain and reducing the price advantage it enjoyed over rivals. Dell's present struggles: underscore the importance of continually assessing a firms strategic position among changing market conditions. Netscape, which once controlled more than 80 percent of the market share in Web browsers, lost its dominant position when customers migrated to Microsoft's Internet Explorer Web browser, which was easy to install and had no significant differences in terms of usability. This example serves to illustrate that: firms with low switching costs can be easily and rapidly overtaken by strong rivals. Leveraging consumers to promote a product or service is known as _____. Viral marketing Firms that compete on _____ rather than operational differences, have no problem adopting third­party ERP software. Product uniqueness Which of the following represents one of the sources of switching costs Search costs Kathy has access to the internet and is able to search and compare the price and quality of the products she wants to purchase. However, Martin does not have access to the internet and stays in a remote town where he is not able to get such details regarding the product or service he wants to purchase. Such a decision situation where Kathy has more or better knowledge about products or services than Martin is known as _____. Information asymmetry Technological improvements can be copied by rivals, leading to a: profit­eroding arms race.

New entrants to a market must ensure that the value they offer exceeds the incumbents' value in addition to any perceived: customer switching costs Businesses benefit from economies of scale when the cost of an investment can be: spread across increasing units of production. The degree to which complete information is available is known as _____. Price transparency Page 3 of 4 The paths through which products or services get to customers are known as _____Distribution channels Page 4 of 4 Page 1 of 3 Chapter 4 Netflix has used the long tail to its advantage, crafting a business model that creates close ties with film studios. What do film studios stand to gain from these ties with Netflix A cut of the subscription revenue from every disk sent out by Netflix A low _____ is usually key to a firm's profitability because acquiring a customer is more expensive than keeping one.

When firms enjoy economies of scale they: leverage the cost of an investment across increasing units of production. Costs that do not vary according to production volume are called _____. Fixed costs Studios have granted Blockbuster distribution terms that enable it to distribute DVDs the day they release. The objective behind this move is to: cut down the increasing power Netflix has over product distribution. Priceline.com is a company and a commercial website that helps users obtain discount rates for travel­ related purchases such as airline tickets and hotel stays. The company facilitates the provision of travel services by its suppliers to its customers. People can directly access a complete array of schedules and fares. This process has, to a great extent, eliminated the travel agency as a middle man. This is an example of: disintermediation Why doesn't Cinematch offer a gross average user rating User tastes are too varied and the gross average rating data is too coarse to offer any value. During Netflix's high­growth period, the DVD­by mail business enjoyed lower marketing costs due to the: word­of­mouth publicity generated by its users. _____ refers to removing an organization from a firm's distribution channel. Disintermediation Netflix has attempted to counter rivals with exclusive content by:securing exclusive streaming rights for several popular shows.
