Physics in Modern Medicine P5.1. Heavy metals such as lead (Z = 82) are excellent x-ray absorbers compared to water (composed of low Z oxygen (Z = 8) and hydrogen (Z = 1)). An average value of Z = 7.42 describes water-rich soft tissues in the body. For safety purposes it is often important to completely absorb x-rays in a protective layer, a process called shielding. Lead is often used to construct shields and protective garments, such as aprons, which...

The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant. Age 37 41...

At −73∘C, the process X⟶Y+Z has a standard free energy change of 11.5kJmol. What is the free energy change (in kilojoules per mole) at the same temperature with [X]=0.65 M, [Y]=1.8M, and [Z]=2.5M? The universal gas constant is 8.314Jmol K. Your answer should have three significant figures. (Round your answer to one decimal place). Do not include units in your answer.
