Question

pls answer the question​

Answer 1

Answer:

b will fall

surface area will help

less surface area cut fast

Answer 2

Answer:

A). Rod B will sink more

REASON - The area (thickness) of Rod B is less than Rod A. So, it will create more pressure because area and pressure are inversely proportional to each other and hence it will sink more.

B). School bags have thick / broad straps to increase the area because if the area will be more, the pressure will be less ( AREA AND PRESSURE ARE INVERSELY PROPORTIONAL TO EACH OTHER) and hence we can carry the school bags easily.

C). Cuttings tools have sharp edges to reduce down the surface area because if the area will be less, the pressure will be more (AREA AND PRESSURE ARE INVERSELY PROPORTIONAL TO EACH OTHER) and hence things can be cut down more efficiently.
