A generator with an rms voltage of 150V is connected in series to a resistor 3.25 kilo-ohm and a capacitor 3.50 microfarad.
A) At what frequency must this circuit be operated for the current to lead the voltage by 17.0 degrees?
B) Using the frequency found in part A, find the average power consumed by this circuit.
A 6.5- kg block oscillates with an amplitude of 0.100 m on a light spring of constant k = 16.0 N/m. What is the maximum value of the block's velocity
Objective questions based on kinematics.
A stunt man whose mass is 70 kg swings from the end of a 3.10 m long rope along the arc of a vertical circle. Assume that he starts from rest when the rope is horizontal; find the tensions in the rope that are necessary to make him follow his circ..
You have a battery marked 6.00 V.When you draw a current of 0.245 A from it, the potential difference between its terminals is 5.13 V
What would be the final temperature of 100g of 16°C water when 107 g of 40°C iron nails are submerged in it? (The specific heat of iron is 0.12 cal/g °C. Here you must equate the heat gained by the water to the heat lost by the nails.)
A hiker's trip consists of three segments. Path A is 9km long heading 60.0° north of east. Path B is 6.0km long in a direction due east. Path C is 5.0 km long heading 315° counter clockwise from east.
A proton moving at 7.00 106 m/s through a magnetic field of magnitude 1.74 T experiences a magnetic force of magnitude 7.40 10-13 N. What is the angle between the proton's velocity and the field
Boat A negotiates a curve whose radius is 363m. Boat B negotiates a curve whose radius is 110m. Each boat experiences the similar centripetal acceleration. What is the ratio of speed of boat A to that of boat B.
The objective lens in a microscope with a 21.0 cm long tube has a magnification of -50.0 and the eyepiece has a magnification of 15.0. What is the focal length of the objective
