A busy waitress slides a plate of apple pie along a counter to a hungry customer sitting near the end of the counter. The customer is not paying attention, and the plate slides off the counter horizontally at 0.84 m/s. The counter is 1.38 m high.
a. How long does it take the plate to fall to the floor?
b. How far from the base of the counter does the plate hit the floor?
c. What are the horizontal and vertical components of the plate's velocity just before it hits the floor?
Draw a constellation pattern for a modern that uses eight equally-spaced phase angles and equally spaced amplitude levels. If the modern operates at 4800 baud, what is its bit rate.
A 10-uF capacitor has a voltage with the following time dependence:v(t)=20*[1-exp(-0.2*t)] in unit of Volt. Determine the current, power, and energy of the capacitor as a function of time
A 35 kHz sinusoidal voltage has zero phase angle and amaximum amplitude of 10 mV. When this voltage is applied across theterminals of a capacitor, the resulting steady-state current has amaximum amplitude of 644.73 microAmps.
The output should have an adjustable linear output voltagerange of between 0 to 5 V and be capable of supplying a current of150 mA throughout the voltage range. The design should include acircuit schematic and provide complete specification of all..
Use MATLAB to make the following plots of fields associated with propagating modes in a rectangular waveguide. The dimensions are a=2.3 cm, b=1.0 cm and the frequency is 18 GHz. Assume that the maximum electric field is 10mV/m.
A car travels at 30 km/hour. The diameter of the tire is 50 cm. Giving consideration to the Nyquist frequency how many shots of the tire must be taken to correctly capture the motion of the wheels
Apply Coulomb's law to obtain an expression for the electric field at any point P (r, 0) on the x-y plane. Show that your result reduces to the expression given by Eq. (4.33) as the length L is extended to infinity.
let a character stream fromthis source be Huffmancoded. Then, let groups of consecutive four message bitsbe encapsulated into 8-bit SEC-DED Hamming code words.Suppose the following two Hamming are received:0101111001100001.
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
(a) Draw the equivalent circuit. (b) Determine the ohmic value of the impedances. (c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in seri..
A 50 ohms lossless transmission line is to be connected to a load of 25 ohm. Use a lamda/4(quarterLamda) length of line of unknown impedance between the load and the 50-ohm line to match it,
