Kinetic (sliding) friction between glass and counter

Reference no: EM139470

Q1. A solenoid is to be constructed that will have a resistance of 5.00 ohms and produce a magnetic field of 0.0400 T at its center when it carries a current of 4.00 A. The solenoid will be made of wire that is 0.500 mm in diameter and have a radius that is 1.00 cm.The resistivity of the copper wire is 1.70 x 10-8 ohm-m

a) how many turns of wire (N) would be essential to make the solenoid? b) How long will the solenoid be?

Q2. Howard the soda jerk at Beas diner slides a 0.70 kg root beer from the end of the counter to a thirsty customer. A force of friction 1.20 N brings drink to a stop right in front of the customer. What is the coefficient of kinetic (sliding) friction between glass and counter?
