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:
Explanation:
Number of molecules = Moles x Avogadro number
= 65 x 6.022 x 10^23
= 3.9 x 10^25
Answer would be B. I provided work on an image attached. Message me if u have any other questions on how to do it
Answer:
This experiment is uncontrolled because two different masses of substance A are used.
Explanation:
A controlled experiment is a structured experiment aimed at testing a particular observation or observations. The setup of a controlled experiment helps to determine the reason why a particular observation occurs and what must have led to it.
In the experiment highlighted above, different masses of a substance were used, they were heated to different temperatures. The set up does not show any correlation between the masses of substances heated and the temperatures. It is even difficult to try to predict the hypothesis for this kind of experimental set up. All the variables in play can best be assumed to be independent of one another.
