it is difficult to cut vegetables with a blunt knife ----explain the reason by applying the concept of pressure
Answers
Answer:
It is difficult to cut vegetables with a blunt knife because it has more area compared to a sharp knife, which means that the pressure exerted by the blunt knife is less than that of the sharp knife.
Explanation:
The blunt knife has a larger area due to its bluntness and the pressure is distributed over a wider surface but when you use a sharp knife, due to its sharpness, the force you apply gets concentrated along the thin edge of the knife and it helps to apply a large pressure on a smaller area. Thus helping in cutting.
Answer:
pressure applied is inversely proportional to area
Explanation:
that's why when a knife is blunt the area of sharp edge of knife increases and thus cutting vegetables becomes difficult while when we apply force with sharp knife the edge is small in area and it applies greater pressure on the vegetable.
