A business letter usually has a full return address (or is printed on letterhead stationery), and has an inside address identifying the person and/or company, street address, city and state it is going to. An inter-office memo does not need all that because the sender and recipient are often in different rooms in the same building so they have the same street address.
Also, buisiness letters are often more formal, concern degotiations between companies, and could later become legal documents if there is a dispute. Inter-office memos often are about mundane topics such as who needs some more rubber bands or Post-it notes.
Disadvantage:Easy to damage when compared to BJT
Preferred stockholders have a greater claim on the assets and profits of a company compared to common stockholders. If a company is liquidated, preferred stockholders have to be paid first before the common stockholders.
Size.
However, compared with sigmoidoscopy, colonoscopy is a longer process, causes more discomfort, and is more costly.
coagulating power of an electrolyte is proportional to its valency. Since valence of Fe3+ is higher compared to that of k+ , it is preferred over potassium chloride
It may be due to the pollution level ie.,the poisonous substance emitted from diesel is more compared to CNG. The cost of CNG is less when compared to diesel.

b'coz t mobility of electrons in NAND gate is 3 times higher than that of NOR gate
Copper has a relatively low resistance, is malleable and easily formed, and it is relatively inexpensive compared to other metals, such as silver, that are also good conductors.
Actually ce configuration is preferred for amplification since it has a current gain of 20-500 and also has appreciable voltage and power gain. It has moderate output to input impedence ratio(about 50).
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
