Determine the mass percentages of each of the three components present in a mixture. The 5 separation techniques are…… 1) Sublimation: involves the heating of a solid that passes directly from the solid phase into the gaseous phase. The reverse process where a gas goes into the solid phase is called deposition or condensation. 2) Extraction: involves using a solvent that selectively dissolve one or more components from a solid mixture. 3) Decantation: involves the separation of a liquid from

LISSAJOUS PATTERNS (INTRODUCTION) OBJECTIVE 1. To use Lissajous figures to take phase measurements. 2. To use Lissajous figures to take frequency measurements. LIST OF REQUIREMENTS Equipment 1. General purpose oscilloscope (10MHz) 2. Function generators (1 Hz to 1 MHz) 3. Digital multimeter THEORY Lissajous patterns are formed when you combined periodic waves moving back and forth with periodic waves moving up and down. This exhibit does this electronically

are different in different cultures. One of the reasons that we feel like a fish out of water when we enter a new culture‚ is that we do not know all of the cues that are used in the new culture. Psychologists tell us that there are five distinct phases (or stages) of culture shock. It is important to understand that culture shock happens to all people who travel abroad‚ but some people have much stronger reactions than others. During the first few days of a person’s stay in a new country‚ everything

continuous. A sine wave represent in graphically where time in X axis & value in Y axis. [pic] Parameters; A sign wave have three parameter • Amplitude • Frequency • Phase Amplitude: The peak amplitude means the energy of a signal. Peak amplitude measured into voltage scale where amplitude may be high or low. Any signal have to covert into voltage for communication where they converted as their energy of amplitude‚

out seems like a whole lot of hassle so I don’t understand why people would do this and just get caught in the end. But I will be listing 5 general phases of a computer attack that one would have to go through to be successful in other words jumping through hoops that are on fire. Phase 1 - Reconnaissance Reconnaissance is probably the longest phase‚ sometimes lasting weeks or months. The black hat uses a variety of sources to learn as much as possible about the target business and how it operates

pass filtering: ωs. The effect of the phase shift is the multiplication of the output with a constant cos (Φ). Therefore one needs to know the phase shift of the demodulation signal in order to demodulate and get the original signal. Q2: Advantages of DSB-LC when compared to DSB-SC Demodulations requires simple circuits while DSB-SC requires complicated circuits Does not suffer from phase shift and frequency errors The receiver does not need to be in phase as required in the case of DSB-SC

Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced

Abstract: One of the primary considerations in preparing pharmaceutical ointments is the properties of different types of ointment base. The types of ointment bases used as vehicles for drugs are selected or designed for optimum delivery of the drugs and also to contribute emolliency or other quasi-medicinal qualities. Ointments properties vary since they are designed for specific uses‚ ease of application or extent of application. The purpose of the lab was to learn the difference between

Q1. Various digital-to-digital encoding techniques are as follows: a) Signal spectrum – a transmission contains lack of high frequency components which means less bandwidth is required and direct current component is also desirable. With no dc component‚ ‘ac’ coupling via transformer is possible. Finally‚ the magnitude of the effects of signal distortion and interference depend on the spectral properties of the transmitted signal. b) Clocking – to provide a separate clock lead to synchronize the
