Consider the elastic head-on collision between a sledge hammer with 9000 g mass and a golf ball with a 4 g mass. The initial velocity of the sledge hammer is 22 m/s, and the golf ball is initially at rest. Estimate the approximate final speed v2 of the golf ball
Read the binary number from the user and store it into a C string (i.e. char[ ]) The c string shall be able to accommodate a 32 bit binary number, note each digit in the binary number is a character, and there must be a null character at the end ..
A circle, centered at the origin with a radius of 2 units, lies in the xy plane. Determine the unit vector in rectangular components that lies int he xy plane, is tangent to thte circle at 3.
An 8-bit A/D converter has Vref- = 2 V and Vref+ = 5 V. The analog input signal vin has a frequency range of 300 Hz to 3.4 kHz. a) If vin = 7 V, what is the binary value on the A/D output pins b) If vin = 1 V, what is the binary value on the A/D outp..
The generator is delivering 48 MW to the bus bar at the rated voltage with its field current adjusted for a generated emf of 46 kV per phase. Determine the armature current and the power factor. State whether power factor is lagging or leading
Find the electric field of a long line charge at a radial distance where the potential is 12V higher than at a radial distance \(r_{1}=1m\) where the magnitude of the electric field is 5V/m .
The electron distribution in the conduction band peaks at energies close to the conduction band edge. Using the Boltzmann approximation, find the energy in the conduction band (as a function of temperature) at which the electron density peaks
An amplifier output is being evaluated by a technician. The output is found to be a sine wave. The measured time lapse from one sine-wave peak to the next is 5 milliseconds.
A 20 V source with a Thevenin Resistance of 3 Ohms is set to the resonant frequency and connected to the RLC circuit. Draw the circuit diagram and determine the magnitudes of the voltage across the capacitor and the total voltage across the RLC ci..
A 25MVA, three phase, 13.5kV, Y-connected, two pole, 60Hz synchronous generator was tested by the open circuit test and short circuit test and tabulated in table 1. If the armature resistance is 0.24 ohms per phase.
A square cross section, air filled toroid has Inner radius 12 cm. outer radius 14 cm. and thickness 2 cm. How many turns are required to produce an inductance of 1 mH
When we give sinusoidal voltage across a capacitor the current across it has 90 degree phase lag. Then this means as voltage increases(sine) the current decreases(cosine)[in 1st quadrant]....Whether this indicates capacitor exhibits negative r..
A piston-cylinder assembly contains 2 kg of water vapor initially at 1 MPa and 250 oC. The water vapor is cooled at constant pressure until the water reaches a quality of 50%. a. Show the process on P-v and T-v diagrams with respect to the sa..
