A 260(omega) resistor is in series with a 9.50×10?2H inductor and a 0.56 (mu)F capacitor. Compute the impedance of the circuit at a frequency of f1 = 500 Hz and at a frequency of f2 = 1000Hz in each case, compute the phase angle of the source voltage with respect to the current.
The drawing shows one horizontal wire with the current going up and one vertical wire with the current going to the right. Point A is dH to the right and dV above the intersection. Point B is dH to the left and dV below the intersection.
A uniform electric field of magnitude 249 V/m is directed in the negative y direction. A +13.4 ?C charge moves from the origin to the point (x, y) = (15.0 cm, 50.8 cm)
A student in an undergraduate physics lab is studying Archimede's principle of bouyancy. The student is given a brass cylinder and using a triple beam balance finds the mass to be 1.25 kg
A flat surface with area 1.6 m2 is in a uniform electric field of 560 N/C. What is an electric flux through the surface when it is oriented as follows.
Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.
A 150 g ball and a 220 g ball are connected by a 36{rm cm}-long, mass less, rigid rod. The balls rotate about their center of mass at 130 rpm. What is the speed of the 150 g ball.
When Capacitor C1 having voltage V is connected with another capacitor C2 having zero charge in parallel with C1 what would be the dissipated energy.
Suppose that a structure of arbitrary complexity has a number of forces applied to it (at various points) and yet is in static equilibrium. The principle of virtual work allows one to write an equation that relates the applied forces.
Both teenagers pull with a force of 55 at an angle of 35 relative to the forward direction, that is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magn..
A fan is spinning at 900 rpm. When its motor is turned off it makes 75 rev before coming to a stop. If the work down by dissipative forces is 44.4J, Find the moment of Inertia of the fan and the torque due to dissipative forces.
A mass of 125g is suspended from a spring of a spring constant of 38N/m. When this mass is pulled down 3mm and set in oscillation, what is the period and frequency of the oscillation? How different would be both, the period and frequency, if the m..
A person exerts a horizontal force of F = 175 N in the test apparatus shown in the drawing. (h = 0.25 m.) Find the horizontal force M that his flexor muscle exerts on his forearm.
