What is the strain on an object, when a force of 3 Newton is applied on it and it expands the length of the object from 4cm to 6 cm?

What is the strain on an object, when a force of 3 Newton is applied on it and it expands the length of the object from 4cm to 6 cm? Correct Answer 0.5

Given:- Force applied=3 N Original length(o)=4cm New length=6 cm Extended length(e)=New length-Original length Extended length(e)=6-4=>2cm Strain (s) = Extended length(e)/Original length(o) Strain (s)=2cm/4cm=>0.5.

Newton, Einstein, and Tesla working alone can do a piece of work in 20, 30, and 60 days respectively. All three of them start the work together, but after x days Newton leaves and then after y more days Einstein leaves and Tesla completes the remaining work. If Einstein had not left, Tesla and Einstein would have completed the remaining work in (y + 6) days after Newton had left. If both Newton and Einstein had stayed, the work would have been completed in (x + 6) days. What is the total number of days taken to complete the work?

In this question, the first and last sentences of the passage are numbered 1 and 6. The rest of the passage is split into four parts and named P, Q, R, and S. These four parts are not given in their proper order. Read the sentence and find out which of the four combinations is correct. S1: A force exists between everybody in the universe. P: Normally it is very small but when one of the bodies is a planet, like earth, the force is considerable. Q: It has been investigated by many scientists including Galileo and Newton. R: Everything on or near the surface of the earth is attracted by the mass of the earth. S: This gravitational force depends on the mass of the bodies involved. S6: The greater the mass, the greater is the earth's force of attraction on it. We can call this force of attraction gravity. The Proper sequence should be:
