On a frictionless table, a glob of clay of mass 0.220 kg strikes a bar of mass 0.600 kg perpendicularly at a point 0.150 m from the center of the bar and sticks to it. If the bar is 1.380 m long and the clay is moving at 8.700 m/s before striking the bar, at what angular speed does the bar/clay system rotate about its center of mass after the impact (in rad/s)?
What is the modulation used to transmit HDTV signals over the air in US terrestrial broadcasting? What is the transmitted bit rate and the compression method?
Assume that we make an enhancement to a computer that improves some mode of execution by a factor of 10. Enhanced mode is used 50% of the time, measured as a fraction of the execution time when the enhanced mode is in use.
A y polarized UPW motion in + x direction in free space has a maximum value of 20 (V/m) at a point x=1.5 (m) with the next adjacent minimum at x=2.75 (m) at time t=0 Obtain the wavelength and the frequency of the wave.
A new government law requires that the lead content of drinking water be less than 1.0 ppb. You are a safety engineer, and you have recently tested your companys drinking water using two methods. Method A gives a reading of 0.85 ppb
Two delta-connvected loads are connected in parallel and powered by a balanced Y-connected system. The small of the two loads draws 10k VA at a lagging Power Factor (PF) of 0.75, and the larger draws 25k VA at a leading PF of 0.80.
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
What should the signal definitions be for the equations, such that the minimal about of hardware (gates) are used assuming we have an abundance of NAND gates Show the signals definitions and resulting circuitry.
A 3-phase transmission line series load of 2000MVA, .8 p.f. lag at 735 kv. The ABCD parameters of the line are : A = .8746 =D, B = j128.33Ω, C = j.0018315 (s). Calculate Vs, Is, voltage regulation and efficiency of the line.
Important information about Frequency Divider, Design a frequency divider circuit that will output three pulse frequencies: 25 kHz, 10kHz, and 2.5kHz. Assume that only a 150 kHz CMOS compatible signal is available for the divider input
you have a RC circuit with an unknown capacitor. You have a 20V source and a 33k ohm resistor. the question states. The voltage Vc for the network has risen to 16V 5seconds after the switch was closed. Determine the value of C in microfarads.
Let x(t) = cos(3/4(t+1/2)+1/4) a. Determine the frequency, the period of x(t) b. Given another signal, y(t)= sin(3/4(t+1)+3/8), is y(t) identical to x(t) Why
