Explanation:
C) is incorrect. The mass is equivalent to the moment of inertia in an angular formula.
The others appear all correct.
T * theta = F * r * theta = F * (r theta) = fx = work
This is the only one that needed explanation. The others should be obvious.
Answer:
1. Planetary Model
2. Protons and Neutrons
Explanation:
1. planetary model is also known as quantum model, which is the model we use nowadays
2. Majority of the mass is from the total of neutrons and protons, electrons are so small that it is not included with the mass

<h3><u>Answer;</u></h3>
<u>An increase in pressure favors the formation of ozone </u>
<h3><u>Explanation;</u></h3>
- Ozone, O3, decomposes to molecular oxygen in the stratosphere according to the reaction
2O3(g) ⇆ 3O2 (g).
- There are more moles of product gas than moles of reactant gas. An increase in total pressure increases the partial pressure of each gas, shifting the equilibrium towards the reactants.
- Therefore; an increase in pressure favors backward reactions towards the formation of ozone.
Answer:250N
Explanation:
Spring constant(K)=500N/m
extension(e)=0.5m
Weight=k x e
Weight=500 x 0.5
Weight=250N
