How does a sharp knife increase pressure when cutting?a)By increasing ...
Pressure is calculated as Pressure = Force ÷ Area. A sharp knife has a smaller contact area, which increases pressure for the same force, making cutting easier. Increasing force also raises pressure but is not the primary role of sharpness, and increasing area reduces pressure, making options A, C, and D incorrect.
