Review the passage. single trees, or small groups of trees in open pastures are exceedingly dangerous during a thunder storm; tall trees on the shores of a river or lake are particularly selected as targets for thunder bolts by the storm king. but the safest place in a thunder storm, next to a house, is a forest. the reason of this is that each wet tree is a lightning rod silently conducting the electric fluid without causing explosions. which best explains how to identify the text structure used in the passage? a) the text structure is compare and contrast; the words but and without indicate this. b) the text structure is problem and solution; the words safest and causing indicate this. c) the text structure is sequence; the words exceedingly and particularly indicate this. d) the text structure is cause and effect; the words the reason of this is indicates this.

The text structure is cause and effect; the words the reason of this is indicate this. So D.

c. spelling errors, if not i am so sorry. but i hope it !

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.
