Question: An uncharged nonconductive hollow sphere of radius16.0cm surrounds a17.0µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along thezaxis, and a hole is drilled in the sphere. Calculate the electric flux through the hole.
A 2722-kg weight is being pushed up an inclined surface at constant speed by a cylinder. The coefficient of friction between the weight and inclined surface equals 0.15. for a pressure of 6.9 MPa, determine the required cylinder diameter.
A car is traveling on a street at 24.6 m/s. An ambulance is behind the car, moving in the same direction and with a speed of 38.7 m/s. The siren on the ambulance is emitting sound at a frequency of 1575 Hz. The speed of sound in the air is 343 m/s..
A 11 GHz uniform plane wave with maximum electric field of 100 V/m propagates in air in the direction of a x-direction. The magnetic field has only a a(z) component ( in the z direction), which is approximately equal to 100 mA/m at x = y = t = 0.
redesign the 1s-counting machine, assigning the states in the binary counting order (S0-S3=00,01,10,11). Compare the cost of the resulting sum-of-product excitation equations with the ones derived in the text.
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
The American Standard Code for Information Interchange (ASCII) has 128 binary-coded characters. If a certain computer generates 100,000 characters/second, determine the following: a. The number of bits (binary digits) requiredper character.
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
Draw a circuit model of the path of current through the human body for a person touching a voltage source with both hands who has both feet at the same potential as the negative terminal of the voltage source.
Given a four-volt peak to peak square wave, calculate the mean-square error in approximating the wave by only its fundamental sinusoidal component. Assume the average value is zero (no DC offset).
1. An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. 2. You are tuned to an AM station at 1200 KHz. Write down the frequency components of the received AM signal.
Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the following.
A 600 V, dc shunt motor has armature and field resistance of 15 ohms and 600 ohms respectively. When the motor runs unloaded, the ine current is 3 A, and the speed is 1000rpm. Calculate the developed torque at a full load armature current of 50 A.
