1. Which star(s) in the table above is most likely going to make a type 2 supernova as it dies? Support your answer with evidence from the data given.
Betelgeuse
2. Which star from the table above would have the longest life span? Support your answer with
data from the table.
3. Which star from the table should have a life span comparable to the earth's? Support your
answer with data from the table.
4. Which star listed in the data is fusing hydrogen the fastest?

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:

come closer and become far apart and become steam/gas
