2.25 amperes
Ohms law dictates that electrical voltage = current times resistance. Since you are given voltage and not the current, you will be dividing voltage by the resistance.
9.0V ÷ 4.0ohms = 2.25 amps

Answer:
Addition of shells increases the distance of outer electrons from the nucleus.
Explanation:
Shielding effect is known as the attraction between the nucleus and an electron of any atom. In other words, it is the reduction in effective nuclear charge on an electron cloud.
Addition of electron shells results in the shielding of electron from nucleus. As the number of electron shells increases then farther will be the electrons placed from the nucleus and hence it will become easier to expel the electrons from outer shells with only little amount of ionization energy.
So, the amount of ionization energy require will be indirectly proportional to the shielding effect because more the shielding of electrons from the nucleus less will be the ionization energy require to expel the electrons.
Question: Whats the earths core made of ?
Answer: The outer core is about 1,400 miles thick and is made of iron and nickel, along with small amounts of other dense elements they have a lot of diffrent pieces that make up the core but this is also found on top of the erths surface
Explanation: so earths core is fascinating to scientest it has so many objects and metals making up the core

Sir Isaac Newton laid the foundations for the creation of modern calculus through his work in the field of mathematics. His discovery of formulas that could be used to derive the areas of curved objects led to many of the mathematical breakthroughs of the last two centuries. He also helped in the field of science by discovering laws such as the universal gravitation law.
