Read the passage. (1) In 1751, the Philadelphia Provincial Assembly had a bell made. (2) It was for the new State House. (3) The bell weighed more than 2,000 pounds. (4) The bell was 12 feet in circumference around the bottom. (5) It came to be known as the Liberty Bell because it was inscribed with a motto about liberty. (6) Unfortunately, the Liberty Bell cracked in 1752 during a test ring. (7) To fix the bell, the Philadelphia Assembly had it recast. (8) Some people say the bell cracked again in 1835. (9) It was tolling for John Marshall’s funeral. (10) However, that is probably just a legend. (11) It is a fact that on February 22, 1846, the bell cracked again. (12) That crack could not be fixed. (13) The Liberty Bell has had a crack in it ever since.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

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.
