Question: The average atomic masses of some elements may vary, depending upon the sources of their ores. Naturally occurring boron consists of two isotopes with accurately known masses ( 10 B, 10.0129 amu and 11 B, 11.00931 amu). The actual atomic mass of boron can vary from 10.807 to 10.819, depending on whether the mineral source is from Turkey or the United States. Calculate the percent abundances leading to the two values of the average atomic masses of boron from these two countries.

Question: For experimental evidence, particularly of previously unobserved phenomena, to be taken seriously it must be reproducible or of sufficiently high quality that a single observation is meaningful.

Question: Distances between points in a plane do not change when a coordinate system is rotated. In other words, the magnitude of a vector is _invariant_ under rotations of the coordinate system. Suppose a coordinate system S is rotated about its origin by angle \varphi to become a new coordinate system \text{S}^{\prime} , as shown in the following figure. A point in a plane has coordinates ( _x_ , _y_ ) in S and coordinates \left( {x^{\prime},y^{\prime}} \right) in \text{S}^{\prime} . (a) Show that, during the transformation of rotation, the coordinates in \text{S}^{\prime} are expressed in terms of the coordinates in S by the following relations: \left\\{ \begin{matrix} {x^{\prime} = x\ \text{cos}\ \varphi + y\ \text{sin}\ \varphi} \\\ {y^{\prime} = \text{−}x\ \text{sin}\ \varphi + y\ \text{cos}\ \varphi} \end{matrix} \right.. (b) Show that the distance of point _P_ to the origin is invariant under rotations of the coordinate system. Here, you have to show that \sqrt{x^{2} + y^{2}} = \sqrt{{x^{\prime}}^{2} + {y^{\prime}}^{2}}. (c) Show that the distance between points _P_ and _Q_ is invariant under rotations of the coordinate system. Here, you have to show that \sqrt{{(x_{P} - x_{Q})}^{2} + {(y_{P} - y_{Q})}^{2}} = \sqrt{{({x^{\prime}}_{P} - {x^{\prime}}_{Q})}^{2} + {({y^{\prime}}_{P} - {y^{\prime}}_{Q})}^{2}}.
