(7, n) b. (12, n) c. (1.33, n) d. (0.75, n) 10. which of the following statements is true?

Explanation:

Step1: Recall Newton's Second - Law formula

Newton's Second Law is $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Solve question 6

Based on the formula, the correct answer for the formula of Newton's Second Law of Motion is $F = ma$. So the answer is B.

Step3: Solve question 7

Given $m = 2$ kg and $F = 10$ N. From $F=ma$, we can find $a=\frac{F}{m}$. Substitute the values: $a=\frac{10}{2}=5$ m/s². So the answer is B.

Step4: Solve question 8

From $a=\frac{F}{m}$, when $F$ is constant, $a$ is inversely proportional to $m$. Increasing the mass $m$ will decrease the acceleration $a$. So the answer is C.

Step5: Solve question 9

Given $m = 4$ kg and $a = 3$ m/s². Using $F = ma$, substitute the values: $F=4\times3 = 12$ N. So the answer is B.

Answer:

1. B. $LXI0$
2. B. $LXI0$
3. C. Increasing the mass
4. B. $LXI0$
