Advantage of travelling Even if you live in a vibrant city and have an exciting job and active social life‚ nothing can replace the unique experiences traveling offers. Visiting a foreign country opens your eyes to how the rest of the world lives; many therefore return home with a new appreciation for their own country while gaining a broader worldview in the process. Remember‚ you only live once‚ so passing up a chance to travel is tantamount to passing up a life-altering experience. 1. Break

brutality around every corner‚ making violence seem almost exciting. When in reality‚ most people will probably never even witness a murder‚ have to deal with gang wars‚ or even be in a crazy gun fight as seen on tv. Do people really believe that Vin Diesel or Tom Cruise live these amazing action packed daily lives? Kids are shown these wild actions on tv‚ but what they aren’t shown is any consequences‚ which makes them believe it’s okay. Hollywood even influences the cultural values of America. Hollywood

both inputs of a differential amplifier equally. ‒ these are interference‚ static and other kinds of undesirable signals picked-up by the circuit. Common Mode Rejection Ratio(CMRR) ‒ measure of an amplifier’s ability to reject common-mode signals. vin(d) = vin1 ‒ vin2 From Loop 1: vin1 ‒ ie1re’ ‒ (ie1 + ie2)RE = 0 vin1 = ie1(re’ + RE) + ie2RE (1) vin2 ‒ ie2re’ ‒ (ie1 + ie2)RE = 0 vin2 = ie2(re’ + RE) + ie1RE (2) express in terms of the current: from (2) ie2 = substitute ie2 in equation 1: vin1

ADC0803‚ ADC0804 ® Data Sheet August 2002 8-Bit‚ Microprocessor-Compatible‚ A/D Converters FN3094.4 Features The ADC080X family are CMOS 8-Bit‚ successiveapproximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These converters appear to the processor as memory locations or I/O ports‚ and hence no interfacing logic is required. The differential analog voltage input has good commonmode-rejection

Mechanical Translational Systems Currently‚ there are two systems of units: One is the international system (SI) or metric system‚ the other is the British engineering system (BES) or the English system. We prefer to use the SI system in this course‚ buy may use either of them whenever necessary. Also‚ within each system‚ we define certain base units. In SI system‚ they are meter‚ kilogram‚ and second. In BES‚ they are foot‚ pound‚ and second. Almost all the other units used in mechanical system

applied; Force = Rate of change in momentum F = ρ Q ΔV F = ρ Q (Vin – Vout) Where; F: the force exerted by the jet on the plate. ρ: the mass density of water (= 1000 kg/m3). Q: volumetric rate of flow (m3/s). ΔV: the change in velocity just after and before impact. The volumetric flow rate in the equation ’Q’ is calculated in the experiment by taking an amount of volume in a known period of time and then use; Q=v/t Vin is calculated in the experiment by first knowing the velocity at
