1. A generator consists of 250 turns of wire each with a radius of 8.7cm. The armature turns with a frequency of 120r/s in a magnetic field of 0.86T.
a) What is the the maximum emf generated?
b) What is the average emf generated during the time interval while the armature is moving one quarter of a turn from a position where the flux through the armature is maximum?
c) What is the average emf generated during one complete turn of the armature? Explain.
2. The output voltage of a 240W transformer is 10.0V and the input current is 12A.
a) By what factor is voltage multiplied?
b) What is the output current?
A steel wire with mass 20.7 g and length 1.11 m is strung on a bass so that the distance from the nut to the bridge is 1.10 m. Calculate the linear density of the string. Compute the wavelength of the string's vibration.
A horizontal force of magnitude 37.2 N pushes a block of mass 3.85 kg across a floor where the coefficient of kinetic friction is 0.585. Through that displacement, the thermal energy of the block increases by 40.6 J. What is the increase in thermal e..
