Answer 1

group flood blunt knife pressure sharp needle relative density hectopascal group higher pressure atmospheric

Answer 2

"1. Fluid - e. same pressure in every directions

"Pascal's law" states that fluid exerts same pressure in all directions.

2. Blunt knife Pressure - d. Lower pressure  

The "cutting edge" of the blunt knife is larger. Hence it has lower pressure.

3. Sharp needle - a. higher pressure

When the pressure and area relation is compared, it is inversely proportional. As the "area of sharpen needle" is less, the pressure is high.

4. Relative density - c. Specific gravity  

"Relative density" or "specific gravity" is the proportion of the "thickness of a substance" to the "thickness of a given reference material".

5. Hecto Pascal - b. Atmospheric pressure  

Hecto Pascal is the "SI unit of pressure" which is normally used to calculate the atmospheric pressure."
