You cause a particle to move from point A, where the electric potential is 11.3 V, to point B, where the electric potential is −

BabaBlast [244]

Explanation:

The electric potential is the electric potential energy per unit of charge

$V=\frac{U}{q}$

Using this definition, we can calculate the electrostatic potential energy change between point A and B:

$\Delta U=U_A-U_B\\\Delta U=qV_A-qV_B\\\Delta U=q(V_A-V_B)$

Electron: $q=-1.6*10^{-19}C$

$\Delta U=-1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=-5.952*10^{-18}J$

Proton: $q=1.6*10^{-19}C$

$\Delta U=1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=5.952*10^{-18}J$

Neutral hydrogen atom: $q=0$

$\Delta U=0$

Singly ionized helium atom: $q=1.6*10^{-19}C$

$\Delta U=1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=5.952*10^{-18}J$

How should ready-to-eat food be stored after it has cooled?

snow_lady [41]

Answer:

The answer is most likely C.

Ready-to-eat foods are stored at the top of the fridge, away from raw foods so that harmful bacteria cannot transfer from the raw food to the cooked food. Raw meat, poultry and fish in sealed containers to stop them touching or dripping onto other foods.
