Which elastic modulus describes the relationship between stress and strain for a block of iron sliding across a horizontal floor? The friction force between the sliding block and the floor causes the block to deform. A. Young's Modulus
B. Shear Modulus
C. Bulk Modulus
D. None of these

B. Shear Modulus

Explanation:

In this scenario, the friction force between the sliding block and the floor causes the block to deform.

Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.

Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.

This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.

Mathematically, Shear Modulus is given by the formula;

Where;

G is the Shear Modulus.

F is the force applied to the object.

A is the area of the object.

l is the length of the object.

Dx is the change in length.

Shear Modulus is measured in Pascals.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
