The correct choice is Buffers.
Buffers contains both acids and bases in equilibrium.when base is added to buffers, they adjust the pH value by releasing hydrogen ions.when acid is added to buffers, they adjust the pH value by consuming hydrogen ions. hence these substances resist any change in their pH value by releasing or absorbing hydrogen ions.This process keeps the pH value constant.
<span> the </span>law of conservation of energy<span> states that the total </span>energy<span> of an isolated system remains constant it would be said to be conserved over time. </span>Energy<span> can neither be created nor destroyed but then rather, it transforms from one form to another.

The acceleration due to gravity of an object with a mass of 10000 g = 42.02 x 10^-16 m/s²
<h3>What is gravitational constant?</h3>
According to Sir Isaac Newton's rule of universal gravitation and Albert Einstein's theory of general relativity, the gravitational constant, indicated by the capital G, is an empirical physical constant that is used to calculate the gravitational effects.
<h3>According to the given information:</h3>
mass of object = 10kg
gravitational constant = 6.67 x 10^-11
radius of earth = 6.3 x 10^6
we know that:
acceleration due to gravity = GM/R²
= ((6.67 x 10^-11)*10)/(6.3 x 10)²
Solving this we get :
42.02 x 10^-16 m/s²
The acceleration due to gravity of an object with a mass of 10000 g = 42.02 x 10^-16 m/s²
