Physics
1 answer:
Stells [14]3 years ago
8 0

Explanation:

After the shock of seeing animals falling from the sky and silence, comes what you may have already imagined; that is, we would die from lack of oxygen - and in about 3 minutes. The worst thing is that not even patients connected to respirators in hospitals or divers equipped with cylinders could survive, since there is a need for pressure to be able to breathe.

A system consists of electrons and protons only. It contains 150 electrons and has a total charge of +22e. What is the mass of t
liubo4ka [24]

According to the statements the number of electrons is 150, then

e = 150

But there is a positive charge of +22e, then the number of protons would be

p = 150+172

If the mass of the electrons is

m_e = 9.11*10^{-31} kg

And the mass of the protong is

m_p = 1.673*10^{-27}kg

We have that the total mass of the system would be

m = e*m_e +pm_p

m = 150 * (9.11*10^{-31})+170(1.673*10^{-27})

m = 2.84547*10^{-25} kg
