Ear "popping" is an unpleasant phenomenon sometimes experienced when a change in pressure occurs, for example,in an airplane. If

you are in a two-seater airplane at 3000 m and a descentof 100 m causes your ear to "pop, what is the pressure change that your ear pops at in millimeters of mercury? If the airplane n

Answer:

Changes in the pressure create the flow of the air to move up and down in the ear and thus create popping sound.

Explanation:

  • The ear-popping is caused by the phenomenon of the opening of the Eustachian tube when one swallows and it might be automatically when you blow our nose or are setting in an airplane and this sound is created when the air enters the middle ear through the tube.

nikklg [1K]

Answer:

1013.25 millibars

Explanation:

  • The standard atmospheric pressure that is measured formthe sea levels to the surface to the high altitudes of the earth is the 1013.25 millibar or is 17 pounds per inches as the air over the higher altitudes is more sensitive and it's measured in pascal.
  • <u>And are a function of the plant's mass and the radius of the surface and the amount of the distribution of the gases and the vertical distribution of the air. And hence is calculated by the values that are reduced to the mean sea levels. </u>

1. Describe the various types of air masses and how they interact to form the four frontal types. Also include the general weath
grandymaker [24]

Answer:

Fronts are defined as body of two air masses and are of four types.

Explanation:

Air masses always be in motion which brings different types of weather. Transition between the two air masses is a front.Basically there are four different types of fronts and the weather which are associated with them also varies.

So the four fronts are:

  • WARM FRONT: It has a wide range from 10-100km.Winds move easterly before the front passes.Chances of rainfall increases when the front cloud approaches . And the wind starts blowing southwesterly or southerly and then the temperature becomes warm with the clouds cleared. Has a huge amount of humidity.
  • COLD FRONT: It is narrow down to a range of <1km.Over a short distance Temperature changes when cold air advances and warm air displaces.Moisture change also causes sharply. At the ahead of the front their is higher moisture content and behind it is lower.
  • OCCLUDED FRONT: When a cold front catches up with a warm front. Their are both cold and warm occulusions. In a warm occulusion colder air is found behind the front and conversely in cold occulusion warmer air is found at the front end. Winds blow either fromsouth or east. And then it gets shifted from west or northwest.
  • STATIONARY FRONT: Boundary between warmer and colder front doesn't move. Precipitation may get developed.
  • Finally the context of midlatitude cyclogenesis leads to understanding the different type of fronts  which helps us to know the kind of weather  and the knowledge help us to predict how the areas near the fronts will be impacted regardless of precipitation' wind and temperature.
