A generator utilizes a coil that has 160turns and a 0.65 T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that all turn of the coil is a square (an approximation), Decide the length of the wire from which the coil is made.
If it is known that an electric dipole is located at the origin andthat its E-field at the point P(2[m], 30°, 90°) isE=4âθ[V/m], find the magnitude and direction of the dipole momentp.
A 275 kg piano slides 4.4 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-36). The effective coefficient of kinetic friction is 0.40. a)Calculate the force exerted by the man. b..
If the elastic limit of copper is 3.68 x108 N/m2, determine the minimum diameter a copper wire can have under a load of 42.2 kg if its elastic limit is not exceeded.
