B. It’s called ferromagnetic
Answer:
D) You will feel the same weight as you do on Earth.
Explanation:
According to Einstein's equivalence principle, states that the weak equivalence principle holds and that: The test result of any non-gravitational experiment in a freely falling laboratory is independent of the velocity of the laboratory and its location in spacetime. This simply means gravitational force is proportional to inertial mass, and the proportionality is independent of the kind of matter.
Hence, You will feel the same weight as you do on Earth because you won't feel any change and will have no way to know that you've left Earth.
At pH = 2 the ratio of the concentration of the hydrogen to the hydroxide ion is 10¹⁰. The hydrogen ion concentration at pH, 2 is 10⁻² and the hydroxide ion is 10⁻¹².
<h3>What is pH?</h3>
The parameter of measuring the concentration of the hydroxide and the hydrogen ion in the solution in order to determine the basic and the acidic nature is known as pH.
The concentration of H⁺ ions is calculated as:
pH = -log [H⁺]
2 = -log [H⁺]
[H⁺] = 10⁻²
The concentration of OH⁻ ions is calculated as:
pH + pOH = 14
pOH = 14 - 2
pOH = 12
Solving further:
pOH = -log [OH⁻]
12 =-log [OH⁻]
[OH⁻] = 10⁻¹²
At a pH = 2, the ratio of hydrogen ions to hydroxide ions:
10⁻² ÷ 10⁻¹² = 10¹⁰
Therefore, at pH = 2 the ratio is 10¹⁰.
