2. Consider this line: “And next came the primal instinct of self-preservation—or was it self annihilation, the instinct that society has grafted on the natural branch?” How do you think “the primal instinct of self-preservation” affects people’s actions? Explain your answer.

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.

1. list two reasons why fossil fuels should continue to be used as a source of energy in america.

why? ? and you will probably get ban

explanation:

yes a mod can probably ban you, and will if you continue to spam. i don't know why you would want to be ban.
