Question

Which of the following belong to the second kind of lever.
(a) pair of scissor (b) pair of forceps (c) door

Answer 1

Answer:

answer is a

Explanation:

pair of scissors

Answer 2

(c) door belongs to the second kind of lever.

(c) door:

A door is classified as a second-class lever since its pivot is at one end, the door's weight is in the middle, and the force to open the door is applied at the other end.

Explanation for incorrect answer:

(a) pair of scissors:

Two pivoting blades make up a pair of scissors. The cutting edges of lower-quality scissors are not exceptionally sharp. So this is the wrong answer.

(b) pair of forceps:

An instrument similar to tongs or pincers is used in surgery and other medical operations for gripping and holding items. So this is the wrong answer.

As a result, the door belongs to the second type of lever.
