An object of mass m = 0:1 kg is dropped from a high tower. Suppose the magnitude of the force due to air resistance is 0:98v2. (The gravitational constant is g = 9:8 m s2 ).a) Write down the dierential equation satised by velocity.b) How long does it take the object to acheive half of its terminal velocity?
How does a squirrel cage induction machine differ from a wound rotor induction machine What are the advantages and disadvantages of each as a motor and as a generator
The line is terminated in a load RL = 25 ohm. Use the bounce diagram to plot V(t) at a point midway along the length of the line from t = 0 to t = 25 ns.
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
The trees can be harvested early at reduced yield: the net profit is then $250T per $1,000 initial investment, for T in years. To the nearest whole year, at what T is the rate of return largest
A manufacturer specification sheet lists the transfer function of a pressure sensor as 45±5% mV/kPa with a time constant of 4±10%. A highly accurate test system applies a step change of pressure from 20 kPa to 100 kPa.
A shunt DC motor has RA = 0.7-ohm and VT =429.6 V. For an output power of 50.4 hp, we have nm = 1,452 rpm and IA = 110.8 A. The field current remains constant for all parts of this problem. Find the rotational power loss in watts.
Sketch a time diagram similar to Figure 3.22 illustrating what happens when a frame gets lost between the sender and the receiver. It should be clear from your diagram how the protocol handles this situation.
Find the system transfer function H(s) = Y(s)/X(s) if the input x(t) and the output y(t) of the system are related by the equation y(t) + 3y(t) = x(t) - x(tau)d tau. Assume y(0) = 0.
A constellation diagram has two points located at (3,0) and (-3,0) on the I(in-phase)-Q(quadrature phase) plane. Find the value of peak amplitude and the type of modulation this diagram represents.
A permanent magnet DC motor with a 10 ohms armature is stopped by dynamic braking. at operating speed, the counter EMF in the motor armature is 15 volts. What will be the peak current through the switch at the instant it shorts out the motor
A natural gas power plant has a condenser that extracts 18,000 Btu/kg of natural gas. Compute the mechanical energy of the turbine and the overall system efficiency.
The power amplifier for a car stereo amplifier has a rated output power of 750 watts when operating at room temperature. Assuming a Class B amplifier with the maximum theoretical efficiency is used,
