Magnitude of the current induced in the coil

Reference no: EM13551647

A coil with 50 turns (radius 15cm) with a total resistance of 4 ohms is placed in a uniform magnetic field directed perpendicularly to the plane of the coil. The magnitude of this field caries with the time according to B=Asin(alpha t) where A=80*10^(-6) and alpha=50pi rads/s. What is the magnitude of the current induced in the coil at t=20ms

What is the index of refraction of the unknown liquid : A laser beam is directed from air (n = 1.0) into an unknown liquid. The angle of incidence is measured to be 60° and the angle of refraction is measured to be 45°. What is the index of refraction of the unknown liquid?

Air resistance is dominant and ignoring lesser contribution : The equation F = arv + br2v2 gives the magnitude of the resistive force (in newtons) exerted on a sphere of radius r (in meters) by a stream of air moving at speed v (in meters per second), where a and b are constants with appropriate SI units.

A variable force given by the analytical expression : A variable force, given by the analytical expression F = 3x2 with x in meters, acts on an object, changing only the kinetic energy of the object. Assume the particle starts out at x=0. a) Make a sketch of the force acting on the object as a function ..

What is acceleration experienced by driver during the crash : Acceleration is sometimes expressed as multiples of g, the acceleration due to Earth’s gravity. In a car crash, the car’s (and driver’s) velocity may go from 26 m/s to zero in 0.15 seconds. On average, what is the acceleration experienced by the driv..
