Imagine that you are in a rowboat with ofcfovab, for your last ride together. you are having a lovely time with our crate, but when you row the boat to the middle of the pond, you decide to drop the crate off the boat (without capsizing the rowboat) and watch it sink to the bottom of the pond. assuming the depth of water in the pond could be measured, explain in detail (using mathematical and diagrammatical support) the relationship between the depth of the water when the crate was in the rowboat and the depth of the water after the crate has sunk to the bottom of the pond. note: mathematical does not imply the use of numbers.

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.

i would say

magnets not strong enough
