An electron moving along the x axis has an initial speed of 1 × 106 m/s at the origin. its speed is reduced to 5 × 105 m/s at the point xp , 3 cm away from the origin. calculate the magnitude of the potential difference between this point and the origin. the mass of the electron is 9.109 × 10−31 kg and the elemental charge is 1.602 × 10−19 c. answer in units of v.

-2.13 V

Explanation:

Given parameters are:

m/s

m/s

C

kg

By conservation of energy principle, we know that the potential difference between two points is equal to the change in the kinetic energy between these points.

Hence,

⇒ V

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
