Presión

The video tutorial explains that pressure is measured in newtons per square meter or pascals. At sea level, the human body is subjected to a pressure of 100,000 pascals. Despite this high pressure, we do not perceive it because the pressure is exerted equally in all directions, both inward and outward.

What is the unit of measurement for pressure?

• Joules

• Pascals

• Newtons

• Watts

At sea level, what is the approximate pressure exerted on the human body?

• 10,000 pascals

• 100,000 pascals

• 1,000,000 pascals

• 10 pascals

Why don't we feel the pressure exerted on our bodies at sea level?

• The pressure only affects objects, not living beings.

• The pressure is too low to be felt.

• The pressure is balanced in all directions.

• Our skin is too thick to sense it.

Which of the following is true about pressure at sea level?

• It is only exerted downwards.

• It is exerted equally in all directions.

• It is higher than at the top of a mountain.

• It is lower than in a vacuum.

What happens to the pressure exerted on the body when it is equal in all directions?

• It increases significantly.

• It is not perceived.

• It causes discomfort.

• It becomes negligible.
