Read robert frost's "the road not taken." what are two key themes of this poem?

two roads diverged in a yellow wood,
and sorry i could not travel both
and be one traveler, long i stood
and looked down one as far as i could
to where it bent in the undergrowth;

then took the other, as just as fair,
and having perhaps the better claim,
because it was grassy and wanted wear;
though as for that the passing there
had worn them really about the same,

and both that morning equally lay
in leaves no step had trodden black.
oh, i kept the first for another day!
yet knowing how way leads on to way,
i doubted if i should ever come back.

i shall be telling this with a sigh
somewhere ages and ages hence:
two roads diverged in a wood, and i—
i took the one less traveled by,
and that has made all the difference.

a) we are faced with choices between good and bad.
b) it is necessary to make choices in life.
c) choices are not mandatory.
d) choices shape a person’s life.

A) We are faced with choices between good and bad.

D) Choices shape a person’s life

in   ¨and yet the books¨   by czelaw miloz the tone is positive since it tells us that when we touch a book, it starts to live and the perspective is in the third person and turns once into the first person. in "the rhinoceros" by eugene ionesco the tone is illogical and absurd   and the perspective is in the third person since it is a play.

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.
