Which of these actions will increase friction? Select three options.scratching a surface to make it rougherpolishing a surface to make it smootherincreasing the size of a flying objectadding extra weight to an objectplacing oil between two surfaces

Scratching a surface makes it rougher, which generally increases friction between surfaces. A larger flying object has more area interacting with the air, so air resistance increases. Adding weight presses surfaces together more strongly, increasing friction; polishing and adding oil generally reduce friction.
