What is sound wave?</h3>
A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.

Pressure has inverse relationship with area of an object. The smaller the area is, more pressure it exerts. Increasing the sharpness of knife(decreasing its area), increases the pressure on an object i.e ability to cut increases on increasing the sharpness.
Hope this helps.
Answer:
Explanation:
1. The net force acting on an object is the combination of all of the individual forces acting on it.
2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
