Question
Consider the following two statements:
  1. Free-electron density is different in different metals.
  2. Free-electron density in a metal depends on temperature.
Seebeck effect is caused
  1. Due to both A and B.
  2. Due to A but not due to B.
  3. Due to B but not due to A.
  4. Neither due to A nor due to B.

Answer

  1. Due to both A and B.

Explanation:

See back effect is caused due to free electron density is different in different metals or free electron density in a metal depends on temperature.

Figure (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. (b) is stretched by the same force F.

What is the maximum extension of the spring in the two cases?

A physical quantity $\text{X}=\frac{\text{a}^2\text{b}^{\frac{-3}{2}}}{\text{c}^4}$ A student says that the relative error in $2\frac{\Delta\text{a}}{\text{a}}-\frac{3}{2}\frac{\Delta\text{b}}{\text{b}}-4\frac{\Delta\text{c}}{\text{c}}.$ Do you agree with the student? If not, what is the relative error in X?
