Force = (mass) x (acceleration) (Newton's second law of motion)
Divide both sides of the equation by 'acceleration', and you have
Mass = (force) / (acceleration)
Mass = 17 newtons / 3.75 meters per second-sqrd = 4.533 kilograms (rounded)
Our solar system formed from a huge cloud of dust and gas called a
c. solar nebula
Based on the nebular hypothesis, our solar system formed from hydrogen gas and interstellar dust. The gas and the dust contracted and formed the early stage of the sun.
To solve the problem it is necessary to use the concepts of Orbital Speed considering its density, and its angular displacement.
In general terms the Orbital speed is described as,
PART A) If the orbital speed of a star in this galaxy is constant at any radius, then,
PART B) This time we have
, where 
is the angular velocity (constant at this case)
PART C) If the total mass interior to any radius r is a constant,
<h2>mass = 25kg</h2><h2>---------------------------------</h2>
force = 75N --- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
acceleration = 3m/s² ---- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
<h3>FORCE = mass × acceleration</h3>
75N = mass × 3m/s²
mass = 75÷3

The pH of the buffer solution is 7.30 for 0.172 m in Hypochlorous acid and 0.131 m in Sodium hypochlorite.
<h3>What is a buffer solution?</h3>
A weak acid and its conjugate base, or a weak base and its conjugate acid, are mixed together to form a solution called a buffer solution, which is based on water as the solvent. They do not change in pH when diluted or when modest amounts of acid or alkali are added to them. A relatively little amount of a strong acid or strong base has little effect on the pH of buffer solutions. As a result, they are employed to maintain a steady pH.
According to the question:
Ka = 3.8×10⁻⁸
pKa = - log (Ka)
= - log(3.8×10⁻⁸)
= 7.42
pH = pKa + log {[conjugate base]/[acid]}
= 7.42+ log {0.131/0.172}
= 7.302
