Exercise 10 Suppose a grocery store normally sells 100 cartons of milk per day and the price elasticity of demand for milk is 1.7. If the store lowers the price of milk by \( 10 \% \), about how many cartons of milk will it then sell per day?

\( A = \left[ \begin{array} { c c c } { AB } \\ { \left. \begin{array} { c c c } { 1 } & { 3 } & { - 1 } \\ { 2 } & { 0 } & { 4 } \\ { 1 } & { 2 } & { 5 } \end{array} \right] \quad B = \left[ \begin{array} { l l l } { 3 } & { 2 } & { 1 } \\ { 4 } & { 0 } & { 1 } \\ { 0 } & { 1 } & { 1 } \end{array} \right] } \end{array} \right. \)

Which type of EM radiation has the: Longest wavelength? Shortest wavelength? Highest energy? Lowest frequency? Give one word for each of the following descriptions. The type of radiation that can travel through flesh, but not through bones. It therefore casts a shadow of bones. The type of radiation that causes the skin to become brown. Visible light with the longest wavelength. Use the wave equation \( v=\mathrm{f} \lambda \) to answer the following questions. Calculate the highest frequency that radio waves can have. Calculate the lowest frequency that gamma rays can have. ( \( \left.1 \mathrm{~nm}=1 \times 10^{-9} \mathrm{~m}\right) \) What is the main difference between radio waves and gamma rays? Radio waves tend to move around objects, while gamma rays tend to move through objects. Give a possible explanation for this phenomenon. What frequencies of light are visible to the human eye? \( \left(1 \mathrm{~nm}=1 \times 10^{-9} \mathrm{~m}\right) \) Calculate the highest energy associated with X rays. ily task 10.2 : Classwork/Homework/Data-interpretation
