In a series RLC circuit, the resistance is 50 ?,the capacitance is 75 µF and the inductanceis 70 mH. The AC generator provides an rmsvoltage of 100 V operating at 1000 rad/s.
1. Find the power supplied by the source. Answer in units of W.
2. Find the power dissipated in the resistor.Answer in units of W.
Two organ pipes play the same fundamental note (i.e., the same lowest frequency). Pipe A is open at one end and closed at the other. Find the ratio of the lengths of pipe B to pipe A
A plastic bucket with negligible mass and specific heat holds 2 kg of water at temperature 20c. Find the entropy change of the ice as it cools and freezes into ice
what magnitude of horizontal force must the person apply to keep it moving with constant velocity? c) If the person continued to push with the force used to start the motion, what would be the acceleration of the trunk.
A 25-N block slides down a plane inclined at 21.2 degrees to the horizontal with constant velocity. Find the total force resisting the motion of the block
A glass window 0.45cm thick measures 80cm by 37cm. To compare the relative efficiency of air and glass as insulators, calculate the heat flows through this window
An x-ray beam with a wavelength of 0.13 nm is directed at a crystal as the angle of incidence increases you observe the first strong interference maximum at an angle of 24.5 degrees. What is the spacing between the planes of the crystal
Radar at an airport tells an air traffic controller that a light airplane is approaching at 220 km/h at 33° north of east. Instruments also tell the air traffic controller that there is a wind blowing at 42 km/h at 25° west of south. What is th..
a 35 kg boy sits atop a sphere of frictionless ice of radius r=2.0m. He begins to slide and eventually falls off. How far above the ground does he lose contact with the ice
