A 7 gram bullet, travelling horizontally at 380 m/s, pierces into your 2kg copy of Halliday, Resnick and Waller sitting on your table. The table and book have a coefficient of kinetic friction of k = 0.3 Find the distance, in meters, that the book and bullet will slide on the table before coming to rest.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

multiply 2kg by latent heat of vap
