Answer:

Magnetism is believed to be caused by the alignment of small, numerous sub-units called : <em><u>Domains</u></em>

<em><u></u></em>

Explanation:

Domains : A magnetic domain is the region in which in which magnetic field of the atoms are grouped together and aligned.

  • In unmagnetized material all the magnetic Domains  point in different direction.
  • In magnetised material (ferromagnets , antiferromagnets) , The Domains point in a particular( fixed Pattern) direction.

A 250 ml sample of saturated a g o h solution was titrated with h c l , and the endpoint was reached after 2. 60 ml of 0. 0136 m h c l was dispensed. Based on this titration, what is the k s p of a g o h <u>. Ksp=1.9×10⁻⁸</u>

<h3>What is titration?</h3>

Titration is a typical laboratory technique for quantitative chemical analysis used to calculate the concentration of a specified analyte. It is also referred to as titrimetry and volumetric analysis (a substance to be analyzed). A standard solution with a known concentration and volume is prepared as the reagent, also known as the titrant or titrator. To ascertain the concentration of the analyte, the titrant reacts with an analyte solution (also known as the titrand). The titration volume is the amount of titrant that interacted with the analyte.

A typical titration starts with a beaker or Erlenmeyer flask being placed below a calibrated burette or chemical pipetting syringe that contains the titrant and a little amount of the indicator (such as phenolphthalein).

PLEASE ANSWER “Tessa uses a toy slingshot to launch a tennis ball across the park for her dog to fetch. For her first launch, sh
Inessa05 [86]

The third launch ( with 300 N force) had  the greatest acceleration of the tennis ball

<h3>Further explanation  </h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

\large{\boxed{\bold{a=\frac{\sum F}{m}}}

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

From the above equation it has been shown that the force acting on the object is directly proportional to its acceleration, so <em>the greater the force exerted on the object, the greater the acceleration of the object produced.</em>
