Read the excerpt from amy tan’s essay “mother tongue.”

i know this for a fact, because when i was growing up, my mother’s “limited” english limited my perception of her. i was ashamed of her english. i believed that her english reflected the quality of what she had to say. that is, because she expressed them imperfectly her thoughts were imperfect.

which phrase from the excerpt uses informal english?

(a)“limited my perception”
(b)“her english reflected the quality”
(c)“she expressed them imperfectly”
(d)“when i was growing up”

(D) “when I was growing up”

Explanation:

Whether a piece of writing is formal or informal depends on the choices of vocabulary, the way it is organized and the tone.

Informal languages tend to be more personal than formal language by using first-person pronouns such as ‘I’ or ‘We’,  is more casual and spontaneous, and may use colloquialisms, contractions, and the active voice instead of the passive one. Likewise, the words in this style tend to be short, and are common while texting, in friends meetings, etc.

“when I was growing up” uses informal language: it is personal ("I"), casual, and the words can be used in informal settings and be understood by anyone. If you wanted to say the same phrase in a more formal way, "At the time of my childhood" would be a good option.

you didnt put the link on, so i cant read the paraphrase

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.
