Answer:
Atom is made up of NUCLEUS and electrons revolving around nucleus.
Nucleus itself contains protons and neutrons. Protons and neutrons are approximately 1680 times heavier than the electrons. So the major contribution to the mass of an atom comes from the nucleus.
Final answer:
The mass of an atom is mostly carried by the nucleons, protons, and neutrons, in its nucleus. Electrons contribute very little to the overall mass of an atom because of their small mass.
Explanation:
Essentially, all of the mass of an atom is due to the nucleons. An atom is primarily composed of protons, neutrons, and electrons. However, the mass of an electron is so small that it contributes very little to the overall mass of an atom. The term 'nucleons' refers to the particles in the nucleus of an atom, namely the protons and neutrons. These particles carry most of the atom's mass given their relatively large mass compared to electrons.

Answer : The distance covered by slow snail in 24 hours is
Explanation :
As we are given that the a slow snail can travel 2.2 cm in 1 minute. Now we have to calculate the distance covered by slow snail in 24 hours.
First we have to convert 24 hours in minutes.
Conversion used : (1 hour = 60 minutes)
As, 1 hour = 60 minutes
So, 24 hour = 24 × 60 minutes
= 1440 minutes
Now we have to calculate the distance covered by slow snail in 24 hours.
In 1 minute, the distance covered by slow snail = 2.2 cm
In 1440 minute, the distance covered by slow snail = 1440 × 2.2 cm
= 3168 cm
=
Now we have to convert 'cm' into 'pm'.
Conversion used :
As,
So,
Therefore, the distance covered by slow snail in 24 hours is

The main issues of using synthetic polymers include toxicity poor biocompatibility etc. Synthetic polymers stay non-degradable for ling time and make the surface polluted.
What are synthetic polymers?
Natural polymers are naturally made substances such as cellulose, starch, glycogen etc. Polymers made by man are called synthetic polymers. Synthetic polymers are diverse and are made through several polymerization techniques.
PVC, polyethylene, polyesters Teflon etc. are very common polymers in daily life. A major class of synthetic polymers include plastics which are major pollutants nowadays.
Most of the synthetic polymers are non-biodegradable and will cause landfill issues. Some them are toxic in nature and might cause several health issues. Blending them with biodegradable polymers is a solution for this.
