Which of the following statements define the pressure? pressure is a force distributed over a length o pressure is a force distributed over an area o pressure is a force distributed throughout a closed volume pressure is the weight of the substance/object under consideration none of the above

Answer:  Option C

Pressure is a force shared over an area

Explanation:

Pressure is the result of a force shared over an area. Pressure is explained as the physical force applied on the body.

The applied force is perpendicular to surface of body per unit area.

The symbol used for pressure is P.

Formula:

P=F/A

Where:

Pis the pressure,

F is the magnitude of the normal force,

A is area of the surface.

The types of Pressures:

Absolute pressureAtmospheric pressureDifferential pressureGauge pressure

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
