A rectangular loop of wire is immersed in a non-uniform and time-varying magnetic field. The magnitude of the field is given by B = 4t2x2 , where t is the time in seconds and x is one dimension of the loop. The direction of the field is always perpendicular to the plane of the loop. The loop extends from x = 0 to x = 3.0 m and from y = 0 to y = 2.0 m. What is the...

A 105‑turn circular coil of radius 2.41 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 14.7 Ω resistor to create a closed circuit. During a time interval of 0.167 s, the magnetic field strength decreases uniformly from 0.481 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval.

Sample practice Ch. 6B – Silimar to Homework 6-15 Consider a horizontal supersonic flow a Mach 2.8 with a static pressure and temperature of one atm and 20 C, respectively. This flow passes over a compression corner with the deflection angle of 16 degrees. The oblique shock generated at the corner propagates into the flow, and is incident on horizontal wall as shown in the figure. Calculate the angle made by the reflective shock wave with respect to the wall...

A uniform spherical shell of mass M = 2.0 kg and radius R = 13.0 cm rotates about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 1.92×10-3 kg m2 and radius r = 4.0 cm, and its attached to a small object of mass m = 4.0 kg. There is no friction on the pulley's axle; the cord does not slip...

Consider a 10x108 m3 lake fed by a polluted stream having a flow rate of 2.0 m3 /s and pollutant concentration equal to 10.0 mg/L. There is also a sewage outfall that discharges 0.5 m3 /s of wastewater that has a pollutant concentration of 100 mg/L into the lake. The stream and sewage pollutants have a decay rate coefficient of 0.20 day-1 (first order). Under these flow conditions the lake remains the same volume (e.g. a stream enters and exits...
