Interpretation:
The terms accuracy and precision needs to be explained.
Concept introduction:
Accuracy is the measure of a degree of closeness of the measured value to its actual value while precision is a measure of a reproducibility of a set of measurements. Accuracy depends on the person measuring while the precision value depends on measuring tool.
Explanation of Solution
Accuracy is the measure of a degree of closeness of the measured value to its actual value while precision is a measure of a reproducibility of a set of measurements. Accuracy depends on the person measuring while the precision value depends on measuring tool. Accuracy can be calculated by using percent error formula while precision determined by the number of significant figures.

- Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related to the total force P by dU dx = P Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of x = x, in terms of the potential energy? 0 P, Force 19 Attraction Total Repulsion x, Distance Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb, corresponding to the peak in total force, is the theoretical cohesive strength.arrow_forwardDenote the dipole for the indicated bonds in the following molecules.
