Get started for freeA metal sphere has a radius \(r\) of \(4.00 \mathrm{~cm}\). What is the volume \(V\) of this sphere in cubic centimeters? The formula for the volume of a sphere is \(V=(4 / 3) \pi r^{3}\), where \(\pi=3.14159 .\)
The density of water at \(4.00^{\circ} \mathrm{C}\) is \(1.00 \mathrm{~g} / \mathrm{mL}\). The density of ice at \(0{ }^{\circ} \mathrm{C}\) is \(0.917 \mathrm{~g} / \mathrm{mL}\). Water is different from most other substances in that the solid phase (ice) is less dense than the liquid phase. Explain why this characteristic makes ice fishing possible.
Use a scientific calculator to do the following calculations. Express each answer in scientific notation and to the correct number of significant figures. (a) \(9.865 \times 10^{3}+8.61 \times 10^{2}\) (b) \(\frac{\left(6.626 \times 10^{23}\right) \times\left(3.00 \times 10^{8}\right)}{4.5 \times 10^{-7}}\) (c) \(\frac{5.6200 \times 10^{-9}}{3.821 \times 10^{9}}\) (d) \(\frac{4.5600 \times 10^{3}-2.91 \times 10^{1}}{5}\), where the 5 is an exact number
Define density, and explain why the unit for density is called a derived SI unit.
(a) Solve the equation \(y=z / x\) for \(x\). (b) Solve the equation \(y=z / 2 x\) for \(x\).
