Determine the number of conduction electrons in a 10.5 ✕ 10−6 kg sample of silver that have an energy between the range of 5.800 eV and 5.834 eV. The density of silver is 10.5 ✕ 103 kg/m3. How can you determine the number of allowed states per unit volume that have energies between E and E + dE? See if you can find a way to express the number of conduction electrons in terms of the volume of the sample, the number of allowed states per unit volume that have energies between E and E + dE, and the range in energies of interest.

The null hypothesis H0 is that the mean customer rating is equal to 75, and the alternative hypothesis H1 is that the mean customer rating is not equal to 75. The test statistic has a normal distribution and the value is given by (x - u) / (o / √n). Based on the test performed, there is enough evidence to support the claim that the mean customer rating is not equal to 75 at the 0.10 level of significance.

The electrons in a CRT TV tube have an energy of about $1 \cdot 10^4 eV$. If $\Delta p/p = 0.01$ in the direction of the electron trajectory for this case, calculate the minimum uncertainty in the position that defines where the electrons land on the phosphor in the picture tube.

9. The diagram below is composed of a square-based right prism topped by a right prism with a triangular base. The base of the prism with a triangular base is an isosceles triangle. The two prisms are equivalent. The sum of the volumes of the two prisms is 6,400m³. If the height of the square-based prism is 8m, what is the total height of the diagram below? 8m

Write a script which will calculate and plot the following function using data values (array) for the Domain x - 0 to x = 20. Have your plot show reasonable titles legend and labels created from the code (not editing the result in the figure window) and each part in a separate colour. Place appropriate open or solid circles at the discontinuities in the function of sufficient size to see.\\ $f(x) = \begin{cases} 2x - 5 & \text{if } x < 5\\ \log(2x^2 + 3) & \text{if } 5 \le x < 10\\ e^{x/100} & \text{if } 10 \le x < 17\\ \sqrt[3]{x^2 + 4} & \text{otherwise} \end{cases}$
