Chlorophyll is the green pigment found in green plants, algae, and cyanobacteria. It is a complex molecule made up of carbon, hydrogen, oxygen, nitrogen and magnesium. Chlorophyll makes it possible for plants to convert carbon dioxide and water, in the presence of sunlight, into oxygen and glucose during the process of photosynthesis.

- The French society in the 18th century was divided into three estates. The first estate consisted of the clergymen, the second estate consisted of the nobles and the third estate consisted of the common people most of whom were peasants.
- While the peasants comprised about 90% of the French population, only few owned land. 60% of the land was owned by the members of the first two estates.
- One of the many reasons why the revolution broke out was because only the members of the third estate paid taxes to the state.
- The members of the first and second estates were exempted from paying any taxes to the king.
- The nobility and the clergy enjoyed many privileges in French society. The nobles extracted feudal dues from the peasants. The latter were also compelled to provide services to the noblemen by working in his fields and house. They also had to serve in the army.
- The church also collected religious taxes from the people known as ‘tithes’. The members of the third estate had to pay direct tax to the state known as ‘taille’. Indirect taxes were imposed on tobacco, salt and many other everyday items. Thus, the third estate was seething with financial difficulties

Matter- Matter is anything which occupies space and has mass is called matter. Air and water, sugar and sand, hydrogen and oxygen etc. Matter is made up of very small tiny particles. Particles of matter have space between them they attract each other.

Momentum is defined as the quantity of motion of the body. It is measured by mass × velocity , as momentum depends upon velocity, and it depends on the direction of the motion of the body as well. Momentum is a vector quantity since velocity is vector while mass is scalar.
Momentum = Mass × Velocity

- Chemical fertilizer and organic fertilizer are branches of fertilizer. Their common feature is providing nutrients to plants. Therefore, both of them improve the productivity ofsoil.
- Natural fertilizers such as manure, animal waste, and compost are considered as organic fertilizer. Fertilizers that synthesize are chemical fertilizers.
- Natural fertilizer includes several nutrients together while chemical or artificial fertilizer incorporates only one or two nutrient.*.On the other hand, natural fertilizer is rich with micronutrients but, chemical fertilizer lacks micro-nutrients.
- There are some advantages of natural or organic fertilizer. They are environmental friendly, improvethe soil texture and water holding capacity, minimize the soil erosion and have some alternative benefitssuch as enhancing microbial growth and applicable as a mulch
- Chemical fertilizer releases nutrients faster. Therefore, it is suitable for fast growing crops like annual crops. It ensures the uniform application of nutrients all over the field. It can immediately recover nutrient deficiency of a plant.

Matter: Everything that has mass and occupies space is called mass.
Mass means weight and space means surroundings. So almost everything around us is matter. Even we are also matter because we have mass and occupy space.
No, sunlight is not a matter because it does not occupy space. Sunlight is a form of electromagnetic radiation and is made of small particles called photons. Photons do not have mass and have very high speed.

The equation of motion is derived based on the Newton’s laws of motion. And it changes accordingly when an object changes with uniform velocity.
Given is that object moves with uniform velocity, that is no change in velocity so there will no acceleration.
As we know {tex}a=v-\left(\frac{u}{t}\right) {/tex}
Here, u = v (due to uniform velocity)
{tex}\begin{aligned} a &=\frac{0}{t} \\ a &=0 \end{aligned}.{/tex}
1st equation of motion is, v = u + at
{tex}\begin{array}{l}{v=u+0 \times t} \\ {v=u}\end{array}{/tex}
2nd equation of motion, {tex}s=u t+\frac{1}{2} a t^{2}{/tex}
{tex}\begin{array}{l}{s=u t+\left(\frac{1}{2} \times 0\right) \times t^{2}} \\ {s=u t}\end{array}{/tex}
3rd equation of motion, {tex}\mathrm{v}^{2}=\mathrm{u}^{2}+2 \mathrm{a} \mathrm{s}{/tex}
{tex}\begin{array}{l}{\mathrm{v}^{2}=\mathrm{u}^{2}+2 \times 0 \times s} \\ {v^{2}=u^{2}}\end{array}.{/tex}
