A chemical organic substance known as synthetic resin is mostly made up of atoms like carbon, hydrogen, and a little amount of oxygen, nitrogen, and Sulphur, among others, joined by specific chemical bonds.

A chemical organic substance known as synthetic resin is mostly made up of atoms like carbon, hydrogen, and a little amount of oxygen, nitrogen, and Sulphur, among others, joined by specific chemical bonds. The primary ingredient in plastic is synthetic resin, which serves as a bonding agent. It securely and tightly attaches other materials to itself in addition to its own structure.

Resin is still the most important ingredient that affects the characteristics and principal applications of plastic. Plastics are created by mixing resin with fillers and additives that appear to modify plastic. Plastic contains between 30 and 60 percent resin by volume.

Synthetic resin is divided into two groups based on the various chemical processes involved in its production: polymer resin (poly-addition), which includes materials like polyvinyl chloride and polystyrene, and condensation resin (poly-condensation), which includes materials like phenolic aldehyde, epoxy, and polyester, among others. Thermoplastic resin and thermosetting resin are groups based on how their properties change when heated.

Answer:

11 , 44

step-by-step explanation

the present age of rohan be x years

then rohan 's father will be 4 x years

6 years later, the sum of their age - 67

4x+6+x+6 – 67

5x - 67 - 12- 55

x - 55/5 - 11

Rohan 's present age - 11 years

Rohan 's father - 4x11 - 44 years

Answer:

type only one question then only I can answer

Explanation:

The intensity of the light incident is given by:

I=AtE

Here, I=20W/cm2, Area A=20cm2, time t=1min=1×60sec=60sec

∴20=20×60E

⇒E=20×20×60

E=24×10^3 J
