It’s me again lol you’re questions are simple the formula is given in the triangle
The answer is C 39 hz
Please look at the attached image below for the explanation
Answer:
No, its not possible for water to dissolve almost anything in the universe.
Explanation:
Solubility of a solute defines the ability of that solute to dissolve in a given solvent. It is defined as the maximum amount of solute dissolved in a solvent at equilibrium. The solution which results from dissolving this maximum amount is called a saturated solution, and one it has been reached, no more solute can be dissolved in it.
Different substances in the universe have diffferent solubilities in water, some very high (soluble) (eg. sugar and salt) and some very low (insoluble) (eg plastics). The substances that are able to form bonds with water (Hydrogen or Ionic) are more soluble than those who are not able to do so.
Answer:
Part a)
Part b)
Explanation:
As we know that the see saw bar is massless so here torque due to two masses is given as
here we will have
now we will have inertia of two masses given as
now we have
now the angular acceleration is given as
so we have
Part b)
Now if the rod is not massles then we will have total inertia given as
so we will have
now the acceleration is given as
That is because there are other forces like the friction forces that apply differently on both of them. The frictional forces applied to the sled are smaller than they are on the father, for example, so it's possible for him to pull it.
