Why does Harriet Tubman point a loaded rifle at one of the runaway slaves?

“Harriet Tubman carried a small pistol with her on her rescue missions, mostly for protection from slave catchers, but also to encourage weak-hearted runaways from turning back and risking the safety of the rest of the group. Tubman carried a sharpshooter's rifle during the Civil War.”

No are u crazy

Explanation:

alone =having no one else present.

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.
