Assuming that the door is relatively thin, the moment of inertia will be the same as that of a rod rotating about an axis at its end. If the mass of the door is 10 kg and its width is 1.5 m, find the angular acceleration of the door after applying..
A rectangular loop of wire in free space joints point A(1,01,) to point B(3,0,1) to point C(3,0,4) to point D(1,0,4) to point A. The wire carries a current of 6mA, flowing the az direction from B to C. A filamentary curent of 15A flows
Two capacitors labeled A and B are connected in series. They have the same charge but A has twice the voltage across it than B has. Which capacitor has the greatest capacitance
Draw schematic for a Bridge (full-wave) peak-rectifier capable of providing de output voltage of 12V with a ±1 V ripple and a load current of 0.5A. Calculate the transformer ratio, the filter capacitor value, and the PIV for the diodes.
Noise is generally viewed as one of a number of general biological stressors. It is felt that excessive exposure to noise might be considered a health risk as noise may contribute to the development and aggravation of stress related conditions suc..
Determine (a)secondary voltage; (b)secondary current; (c)primary current; (d)input impedance at primary terminals of transformer; (e)active, reactive, and apparent power input to transformer.
A conical section of material extends from 2.0 cm = r = 9.0 cm for 0 = (theta) = 30° with (permitivity) = 9.0 and (omega) = 0.020 S/m. Conductive plates are placed at each radial end of the section. Determine the resistance and capacitance of the ..
Two capacitors are connected in parallel across the terminals of a battery. One has a capacitance of 1.97 mF and the other a capacitance of 4.11 mF. These two capacitors together store 5.47 X10^-5 C of charge. What is the voltage of the battery
an automobile travels 1200ft in 30s while being accelerated at a constant rate of 1.8 ft/s^2. Determine (a) its initial velocity, (b) its final velocity, (c) the distance traveled during the first 10s
A jogger accelerates from rest to 3.75 m/s in 3.58 s. A car accelerates from 16.7 to 31.6 m/s also in 3.58 s. (a) Find the magnitude of the acceleration of the jogger. (b) Determine the magnitude of the acceleration of the car.
You are designing a PCS base station that operates at 1800 MHz. The receiver is co-located on a tower with UHF police and business radio systems that operate at 450 MHz. Since the the 4th harmonic from the UHF system is directly in the PCS band
