Q1. A dockworker applies a constant horizontal force of 79.0 to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves the distance 13.0 in a time 5.40.
Q2. A step-up transformer has 300 turns on its primary coil and 90000 turns on its secondary coil if the current flowing through the secondary is 5 amps what is the current flowing in the primary?
Q3. A 22.5-ohm and a 14.8-ohm resistor are connected in parallel across a 28.8-V battery. Find out the voltage drop (in Volts) across the 22.5-ohm resistor.
