11. According to Newton's 2nd Law, which of the following statements is CORRECT? (READ each statement CAREFULLY!)

Option (b) is correct.

Explanation:

The net force acting on an object is given by :

F = ma

Where

m is mass

a is acceleration

The force is acting on an object is directly proportional to its acceleration. It means if the force acting on an object is twice then it will accelerate twice. Hence, the correct option is (b).

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
