$\Delta KE=3.71\times 10^{-15}\ J$

Explanation:

It is given that,

Potential difference, $PE=2.32\times 10^4\ V$

Using the conservation of energy as the potential energy lost by an electron gets converted to the kinetic energy gained by it. Its relation is given by :

$\Delta KE=\Delta PE$

Since, $\Delta PE=q\Delta V$

$\Delta KE=q\Delta V$

$\Delta KE=1.6\times 10^{-19}\times 2.32\times 10^4\ V$

$\Delta KE=3.71\times 10^{-15}\ J$

So, the kinetic energy gained by the electron is $3.71\times 10^{-15}\ J$

Permian-Triassic extinction theory stated that the mass extinction happened because huge asteroids falls down the earth and wiped out the dinosaur era.
Personally, i don't believe this theory because many pieces of evidence was found from the fossil that indicated the die-out happened gradually over million of years which contradict the current extinction theory
