The question is incomplete, the complete question is :
Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of
kg and the mass of bacterium is on order of
kg
Answer:
The total numbers of atom in bacterium are
.
Explanation:
Mass of hydrogen atom, m=
kg
Mass of bacterium , M=
kg
Mass of bacterium atom =m'
Given ; 

let the number of atoms in bacterium be N


The total numbers of atom in bacterium are
.
Answer:
will cloning technology be useful?
Explanation:
Answer:
electrons
Explanation:
The photoelectric effect occurs when electrons are emitted from metal when the metal is struck by light of certain frequencies.
Some of the applications of this effect include photomultipliers (which are a key component in spectroscopy instruments) and night vision devices.
