- How much money would a “meganaire” have?
- At one time Bill Gates was worth \begin{align*}50\end{align*}
50 billion dollars. Express this in words using the science prefixes for sizes. - 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 \begin{align*}\;\mathrm{eVs}\end{align*}
eVs ) of the particle’s energy change? - A particle of negligible mass moves between two plates of a linear accelerator as shown in Figure 18. How much energy (in \begin{align*}\;\mathrm{eVs}\end{align*}
eVs ) does the particle’s energy change by? - A particle of negligible mass moves between two plates of a linear accelerator as shown in Figure 19. How much energy (in \begin{align*}\;\mathrm{eVs}\end{align*}
eVs ) does the particle’s energy change by? - What is the centripetal acceleration needed to turn a particle with a mass of exactly \begin{align*}100\end{align*}
100 protons traveling at \begin{align*}2.00 \times 10^8\;\mathrm{m/s}\end{align*}2.00×108m/s around a ring the size of the LHC (\begin{align*}\mathrm{circumference} = 27 \;\mathrm{km})\end{align*}circumference=27km) ?
