Answer to Question #275994 in Physics for MRM

Question

a) Define the elastic modulus. Explain the different types of elastic modulus.

b) State and explain Einstein's Photoelectric Effect theory.

c) If 12𝑁 force is applied to a fluid of cross-section 5.34 𝑐𝑚2 with a shearing rate of 0.7 𝑠 −1 then find the viscosity of the fluid

Answer 1

a) The elastic modulus is the property of a solid within which the external effort does not cause deformations that cannot be restored.

The types:

Young's modulus.

Shear (Rigidity) modulus

Bulk modulus.

b) A quantum of light falling on metals causes it is to emit electrons.

c) Determine the value:

$$\gamma=\frac F{Au}=31100\text{ Pa}·\text s.$$
