The force equal but opposite to the one shown is : ( D ) The force that the branch applies to the kitten
<h3>Opposite and equal forces </h3>
The force of gravity/weight of an object is equal and opposite to the reactive force because it cancels the effect of the weight of the object on the surface. In option D the force that the branch applies to the kitten resting on it is equal and opposite to the weight of the kitten.
Hence we can conclude that The force equal but opposite to the one shown is The force that the branch applies to the kitten.

<u><em>Your questio lacks the diagram but I have provided a general answer within the contest of your question </em></u>
Answer:
solvent = substance that can dissolve other substances
solute = substances that are dissolved
Scientific law = Describe what phenomena happen , Theory = Explains why phenomena occur
<u>The </u><u>emperical formula </u><u>can be </u><u>calculated </u><u>as follows:</u>
<u>mass :</u> 4.12g of N and 0.88g of H
<u>moles:</u> 4.12g/14.007 and 0.88g/1.008
<u>moles:</u> 0.294 and 0.873
<u>moles/smallest number</u>: (gives the ratio of atoms)
0.294/0.294 and 0.873/0.294
1 and 2.969
1 and 3
The simplest ratio of N : H is 1 : 3
<u>Hence the </u><u>emperical formula </u><u>is </u><u>NH3</u>
<u>Explanation:</u>
1. The emperical formula can be found by getting the <u>simplest ratio of atoms in a molecule.</u>
2. To get the simplest ratio of atoms we find out the <u>number of moles of each atoms in it.</u>
3. From the number of moles of atoms we can find the simplest ratio of each atom by dividing the <u>number of moles by the smallest number.</u>
