Hi
i will mark you as brainliest
reply to my questions
1) how do we get cotton fiber from cotton bolls?
2) write 3 steps involved in the processing.
remember i will mark you as brainliest!

Cotton fibre is a plant seed fibre that needs to be harvested and then separated from the seed. Harvesting is carried out by handpicking the cotton boll from the field or by automatic harvesting using a spindle picker. The process involved in separating cotton fibre from seeds is called ginning.

Explanation:

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.
