Explanation

In indirect speech, the question is converted into a statement.

The question "Can I go and drive, father?" becomes "Jack asked his father if he could go and drive."

The pronoun "I" changes to "he," and the verb "can" changes to "could" in reported speech.

Explanation

Given: A : B = 3 : 1 and B : C = 1 : 2.

To find A : B : C, make the ratio of B the same in both expressions.

A : B = 3 : 1 means A = 3B.

B : C = 1 : 2 means C = 2B.

So, A : B : C = 3B : B : 2B, which simplifies to 3 : 1 : 2.

Now, multiply the entire ratio by 5 to make the B value in all ratios equal: 3 : 5 : 10.

The individual forces have opposite directions, even though their effects cancel out.
