Slope of stress-strain curve in elastic deformation region is a. plastic modulus b. poisson's ratio c. elastic modulus d. none the these a) all of these

c) Elastic Modulus

Explanation

As we know that when deformation is under elastic limit then stress applied to the given material is proportional to the strain developed in it

So here we can say that since they both are directly proportional to each other so the proportionality constant here is known as Modulus of elasticity.

So we can say it is given as

so now if we draw a graph between between stress and strain then it must be a straight line and the the slope of this straight line is given as

So here correct answer will be

c) Elastic Modulus

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
