Write the acid for each conjugate base: ch3nh2 and h2po4

Correct answer choice is:

3) Friction

Explanation:

Low viscosity relates to materials that are thin, such as water, while high viscosity materials are thick. The viscosity of a fluid is a sum of its opposition to progressive deformation by shear strain or tensile stress. For liquids, it compares to the simple idea of thickness, for example, honey has a very greater viscosity than water.
