Varun said to Ayaan,'' you should take care of your old parent .'' (reported speech direct to indirect)

Varun told Ayaan that he should take care of his old parent.

Explanation:

In reporting or writing speeches, the direct form is when the exact words of the speaker are used along with the speech marks/ inverted commas. But in the indirect speech form, the inverted commas will be removed and the verbs in the direct speech are to be changed according to their tenses. This means that if the verb is in the present tense in the direct speech, then the indirect speech will use the corresponding past tense of that verb.

In the given example, Varun is talking to Ayaan about his (Ayaan's) old parent. Thus, the "you" and "your" in the speech refers to Ayaan. So, we take out the commas and the inverted commas and change the pronouns accordingly. And the modal verb "should" remains unchanged in a reporting speech.

Thus, the indirect speech of the given speech becomes-

Varun told Ayaan that he should take care of his old parent.

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.
