Answer:
h = 16.67m
Explanation:
If the kinetic energy of the cylinder is 510J:
Where the inertia is given by:
Replacing this value:
Speed of the block will therefore be:
By conservation of energy:
Eo = Ef
Eo = 0
So,
Solving for h we get:
h=16.67m
Answer:
2 in front of water and 1 in front of oxygen
Explanation:
This question is describing balancing a chemical reaction. A balanced chemical reaction has the same number of atoms of each elements on both the reactant and product side. According to the question, the reactants contains 4 atoms of oxygen. The reactants give rise to water (H20) and O2 in the products side.
This reaction is most likely the decomposition of hydrogen peroxide (H2O2) as follows:
H2O2 (l) ----> H2O (l) + O2(g)
Based on the description, H2O2 will be 2H2O2 as it is said to contain four atoms of oxygen. This means that, in order to have a balanced equation, we must place coefficient 2 in front of water and coefficient 1 in front of oxygen. That is;
2H2O2 (l) ----> 2H2O (l) + O2(g)

That's called an "acceleration" or "slowing down".
