In general, atmospheric pressure is greatest near earth's surface and as you move upward away from sea level.
a. decreases
c. stays the same
b. increases
d. doubles

The correct answer to the question is : Decreases.

EXPLANATION:

In general,the atmospheric pressure is always highest near the surface of earth.

As per the question, we are moving up. The more we go above the surface of earth, the air density gradually decreases.

The air pressure is the force exerted by air per unit area. It is the air density which determines the pressure exerted on a particular location.

As there is decrease of air density when we go upward from see level, the pressure exerted by air molecules decreases.

Hence, the atmospheric pressure decreases when we move upward from the sea level.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
