Answer 1

Answer:

Pressure is defined as the force per unit area. i.e.,

Pressure=

Area

Force

Blunt blades have larger area compared to the sharp-edged blade.

According to above equation, if area is more, you have to apply more force to get the same pressure. Hence, it is difficult to cut the cloth using a pair of scissors with blunt blades

Answer 2

Answer:

Blunt blades have larger area compared to the sharp-edged blades. Thus, the applied force produces a lower pressure in case of blunt blades, which makes it difficult to cut the cloth.
