<span>The law of sines can be solved when you know any two angles of a triangle and a side (AAS-case). The second case is when you know two sides and a non-included angle (SSA-case). Recall law of sines is Sin(A)/A = Sin(B)/B = Sin(C)/C .</span>
The kinetic energy of the pendulum is increasing and the potential energy is decreasing. Potential energy is being converted to kinetic energy.
I hope this helps!
This is an example of displacement reaction
<u>Explanation:</u>
- The chemical reaction in which the one element replaces the other element in a compound is called a displacement reaction. This reaction is also called a replacement reaction.
AB + C -----> AC +B
2ZnS + 3O2 -----> 2ZnO + 2SO2
- This happens when A is more reactive than B and gives a stable product. Here the zinc sulfide compound reacts with the oxygen element to the stable product of zinc oxide and sulfur dioxide.
- In short, the more reactive element displaces the less reactive element is called a displacement reaction.
