“Nothing there!” said Peter, and they all trooped out again – all except Lucy. She stayed behind because she thought it would be worth while trying the door of the wardrobe, even though she felt almost sure that it would be locked. To her surprise it opened quite easily, and two moth-balls dropped out." 4. How did Lucy find the wardrobe? *

A. She was trying to hide from Susan, who was being mean to her.
B. She was looking for a place to store her belongings.
C. She was exploring in the room and wanted to see what was inside.
D. She heard someone inside calling her name and went in to see what was making that noise.

C

Explanation:

"She stayed behind because she thought it would be worth while trying the door of the wardrobe"

This shows that she was exploring.

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.

most likely you should find things like facts and important information to you understand. i hope this .
