1- If the diameter of a spherical water droplet is 100.0 µm, how much energy is required to increase the diameter of the water droplet by 3.0 µm? The surface tension of water is 1.0 x 10-3 J/m2.
2- A metal crystallizes in a face-centered cubic lattice. The radius of the atom is 196 pm and the density of the element is 1.55 g/cm3. How many atoms are there per unit cell?
3- 10-8 cm. The chloride ions are touching each other along the face diagonal of the unit cell. The lithium ions fit into the holes between the chloride ions.´Lithium chloride crystallizes in a face-centered cubic structure. The unit cell length is 5.14 How many chloride ions are there in this unit cell?
what are the different methods used in frequency response analysis
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Consider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a data rate of 2 Kbps (2 thousand bits/sec) which is spread to 2 Mcps
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
Develop the Datapath; draw it under VISIO for this java code : input . x - the abscissa at which the linear interpolation is to be evaluated xi[]- the arrays of data abscissas yi[]- the arrays of data ordinates imax- size of the arrays xi[] and yi[]
Evaluating Coding Gain, CNR, and BER of a DSSS-CDMA Transmitter, a. A DSSS-CDMA transmitter sends message signals at a rate of 5.0 kbps using a long chip sequence with a rate of 1 M chips per second. In the receiver, what is the processing gain (a..
What is the symbol rate of the earth station transmissions? What is the bit rate of the earth station transmissions? What is the duration of the burst transmission from each earth station?
You have an amplifer with a nominal open-loop gain of 1000 (A = 1000), but the variance in the gain is 20% (meaning that the open-loop gain ranges in value from 800 to 1200). You want to use feedback to try to desensitize the gain.
Give a different equation, in terms of the input and output, to describe the system. Is the system stable?
Design an alarm circuit to be used in a process control system. Temperature (T), pressure (P), flow (F), and level (L) of a fluid are each monitored by separate sensor circuits that produce a high logic output signal when the following indicated p..
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
Use the immediate addressing mode to add four to each value that is loaded to accumulator. Store the results in Locations 13-15. Let's assume that in Locations 10-12 we have the values 5, 6, and 7. After executing your code, the values in Location..
