If you could save just one item from a disaster, what would it be? Describe this item and explain why you treasure it. Was it a gift or something
you bought for yourself? How does that make it even more important to you?

the correct answer is

1. lived in castle in naples

2.educated in monastery

3.received a doctorine in theology

4.taught in paris

5. studied in dominican monastery

1. b

2. a deadly disease

4. at the same time

5. a) true

b) true

c)false?

d)false?

7. para.1 = c

para.2 = d

para.3 = f

para.4= b

para.5= e

para.6 = a

what does the teacher mean

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.
