A transformer has 500 loops in its primary coil and 5,000 loops in its secondary coil. What is the voltage in the primary coil if the voltage in the secondary coil is 20,000 v?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
