1: An open bottle in the lab contains crystals of Na2 SO4 . The temperature is 25 °C, the pressure 1 bar, and the relative humidity 85%. Determine whether the formation of the decahydrate according to the reaction below, Na2 SO4 + 10H2 O = Na2 SO4 · 10H2O, can take place under these conditions. What is the minimum relative humidity that will allow the reaction to proceed in the forward direction?
Male frogs give calls that attract female frogs to approach and mate. Researchers examined mating calls of closely related tree frogs in South America. If reinforcement of postzygotic isolation is occurring
The current in a single-loop circuit is 5.0 A. When an additional resistance of 2.0 O is inserted in series, the current drops to 4.0 A. What was the resistance in the original circuit
A synchronous motor is rated as 250 hp, 4.8 kV connected 60 Hz 12 poles with Xs=0.6 pu and Rs=0.01 pu. The motor rotational losses are 1.5 kW and the excitation power is 6 kW. The motor is supplied by rated voltage at the stator.
Consider LTI system S with impulse response h(t) = u(t) - u(t-2). A) Let x1(t) = d/dt(u(t) - u(t-2)). What is the output of the system B) Let x2(t) = cos(pi*t). What is the output of the system
c. Name and briefly explain three fabrication methods for quantum wires. d. Name three potential applications for quantum wires.
The data inputs I0 through I7 are wired as follows: I0 = I1 = 0, I2 = I6 = , I3 = I5 = I7 = 1; and I4 = D. (a) Determine the Boolean function that the MUX implements. (b) Implement the function using a 4×1 MUX with minimum extra logic gates.
Can you do a survey paper on Wavelet and Subband Coding - I need 10 pages and I will provide the references.
compute the fourier transform of the following signals, using the symbolic manipulator to perform the integrations. Plot the signal x(t) and the magnitude |X(&)| of the fourier transform a) x(t) =2e ^ (-4t) cos (10t) u(t)
Let the component at Omega(C) = 2pi* 3000 be the corrupting signal. Design an appropriate lter to lter out this component of the input. You can use fir1 command for this. Plot the frequency response of this lter.
Show (prove) that the signal 3^j2t is an eigenfunction of any LTI system, and nd the formula for the eigenvalue. That is, use the convolution integral and simplify to show that if you input 3^j2t into an LTI system
