Answer:
Electroplating involves deposition of a thin layer of metal onto the surface of a substance(compound) through electric current. This helps preserve the substance(compound) from rust and oxidative damage.
As an entrepreneur which has been provided a loan by a bank to set up a small electro plating unit. I would venture into electroplating electronic/electric appliances parts.This is because these types of appliances are in vogue now and used my millions of people for their day to day activities. This means that more people will come for various degrees of production and repairs which would include electroplating . This translates to more customers and more money for the repayment of the loan.
Answer:
the net electric charge of the iron atom is 2.24 × 10⁻¹⁸ C
Explanation:
Given the data in the question;
we know that neural iron atoms should have same number of protons and electrons i.e 26 and 26 but in the sun's atmosphere, many of their electrons stripped away.
so; we have 26 protons and 12 electrons, meaning ( 26-12=14) 14 electrons have been stripped away.
when we loss electron, we gain positive charge
so, the Net charge of the iron atom of with 26 protons and 12 electrons will be;
q = 26 ( proton charge) + 12( electron charge )
we know that; a singular proton has a charge of 1.6×10⁻¹⁹ C
protons carry negative charge while electrons carry negative
we substitute
q = 26 ( 1.6×10⁻¹⁹ ) + 12( -1.6×10⁻¹⁹ )
q = 2.24 × 10⁻¹⁸ C
Therefore, the net electric charge of the iron atom is 2.24 × 10⁻¹⁸ C
La gravedad te acelera a 9.8 metros por segundo por segundo. Después de un segundo, estás cayendo 9.8 m/s. Después de dos segundos, estás cayendo 19.6 m/s, y así sucesivamente. Es la raíz cuadrada porque caes más rápido cuanto más caes.
