1.	b) A sharp knife is more effective than a blunt knife. Why?
Answer» The area under the sharp knife is less than the area under the blunt knife. Hence, the pressure exerted by the sharp knife is more than the pressure exerted by the blunt knife on an object. Therefore, when a same amount of force is applied on both the knives, the sharp knife penetrates deeper into the object than the blunt knife. the sharp knife has less area than blunt knife (less area =more amount of force) and blunt knife has large area than sharp knife (large area= less amount of force)... so easy😉😉😉😉😉😉😉😉 A sharp knifecuts objectsbetterbecause due to its very thin edge, the force of our hand falls overa sharpsmall area of the object producing a large pressure. ... Ablunt knifehas a thicker edge and does not cut the object easily.
