An L-R-C series circuit is constructed using a 175? resistor, a 12.5?F capacitor, and an 8.00-mH inductor, all connected across an ac source having a variable frequency and a voltage amplitude of 25.0 V. At wo= 3160 rad/s, find the potential difference across the ac source, the resistor, the capacitor, and the inductor at the instant that the current is equal to one-half its greatest positive value.
A 13 g bullet traveling 217 m/s penetrates a 2 kg block of wood and emerges cleanly at 153 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
At one instant a bicyclist is 49m due east of a park's flagpole, going due south with a speed of 14 m/s. Then 40s later, the cyclist is 49m due north of the flagpole, going due east with a speed of 14m/s. For the cyclist in this 40s interval, what..
A 30 cm spring is compressed to 2 cm. a force of 200 N was used to do this. How much potential energy is stored in the spring
A rotating cylinder about 12.00 km in length and 8.00 km in diameter is designed to be used as a space colony. With what angular speed must it rotate so that the residents on it would experience the same acceleration because of gravity on Earth.
fired horizontally at a speed of 550, goes completely through the block, emerging at a speed of 180 . Illustrate what is the speed of the block immediately after the bullet exits?
In each cycle of its operation, a refrigerator removes 8 J of heat from the inside of the refrigerator and releases 22 J of heat into the room. How much work per cycle is necessary to operate this refrigerator.
A 340 g air track cart traveling at 1.25 m/s collides elastically with the 300 g cart traveling in the opposite direction at 1.33m/s. What is the speed of the 300g cart after collision.
What is the amplitude of the subsequent oscillations. A catcher "gives" with a baseball when catching it. If the baseball exerts a force of 519 N on the glove, so that the glove is displaced 10.0 cm, how much work is done by the ball.
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
A wire coil is oriented so that its plane is perpendicular to a magnetic field of 0.58 T initially pointing to the left. What is the average induced emf, if the diameter of the coil is 49 cm
An ion source is producing 6Li ions, which have mass 9.99 x10-27 kg and charge +e. The ions are accelerated by a potential difference of 30 kV and pass horizontally into the region in which there is a uniform vertical magnetic field of magnitude B..
