The four classes of polymers are:
1. Nucleic acids. Examples are DNA and RNA
2. Protein. Examples are enzymes and hemoglobin
3. Carbohydrates. Examples as starch and glycogen
4. Lipids. Examples are triglycerides and phospholipids
The building blocks of nucleic acids are called bases and there are four types known as Guanine, Adenine, Thymine and Cytosine.
The building blocks of carbohydrates are glucose molecules.
The building blocks of protein are amino acids.
The building blocks of lipids are a combination of fatty acids and glycerol.
Answer:
We know that force applied per unit area is called pressure.
Pressure = Force/ Area
When force is constant than pressure is inversely proportional to area.
1- Calculating the area of three face:
A1 = 20m x 10 m =200 Square meter
A2 = 10 mx 5 m = 50 Square meter
A3 = 20m x 5 m = 100 Square meter
Therefore A1 is maximum and A2 is minimum.
2- Calculate pressure:
P = F/ A1 = 30 / 200 = 0.15 Nm⁻² ( minimum pressure)
P = F / A2 = 30 / 50 = 0.6 Nm⁻² ( maximum pressure)
Hence greater the area less will be the pressure and vice versa.
