1. How much money would a “meganaire” have?
2. At one time Bill Gates was worth 50\begin{align*}50\end{align*} billion dollars. Express this in words using the science prefixes for sizes.
3. A particle of negligible mass moves between two plates of a linear accelerator as shown in Figure 17. By how much does the energy (in eVs\begin{align*}\;\mathrm{eVs}\end{align*}) of the particle’s energy change?

4. A particle of negligible mass moves between two plates of a linear accelerator as shown in Figure 18. How much energy (in eVs\begin{align*}\;\mathrm{eVs}\end{align*}) does the particle’s energy change by?

5. A particle of negligible mass moves between two plates of a linear accelerator as shown in Figure 19. How much energy (in eVs\begin{align*}\;\mathrm{eVs}\end{align*}) does the particle’s energy change by?

6. What is the centripetal acceleration needed to turn a particle with a mass of exactly 100\begin{align*}100\end{align*} protons traveling at 2.00×108m/s\begin{align*}2.00 \times 10^8\;\mathrm{m/s}\end{align*} around a ring the size of the LHC (circumference=27km)\begin{align*}\mathrm{circumference} = 27 \;\mathrm{km})\end{align*}?
