Answer:
The value is
Explanation:
From the question we are told that
The wavelength is 
The velocity is 
The mass of electron is 
Generally the energy of the incident light is mathematically represented as

Here c is the speed of light with value
h is the Planck constant with value 
So

=> 
Generally the kinetic energy is mathematically represented as

=> 
=> 
Generally the ionization energy is mathematically represented as

=>
Formula for kinetic energy is 1/2mv^2 so that answer should most probably be 94521.6J
C. A little backward, 100 or 110 degrees
It will sink because it is heavier. The density of water 1.00 g/ml
