Warm air aloft is normally higher pressure relative to colder air aloft, which is normally of lower pressure (at equivalent alti
Allisa [31]

Answer:

the statement given is False.

Explanation:

The pressure is defined by

     P = F / A

The force of the air is its weight,

     P = W_air / A

The weight of an air column on us depends on the energy of the molecules that is related to the temperature

      E = 3/2 K T

 When the air is warmer it has more energy so the molecules can move more distance and therefore the average density of the gas decreases, as the density decreases, the weight of the column on us also decreases, therefore the pressure low.

The correct statement is: When the air is hotter it has less pressure than when the air is cold.

 It is summary the statement given is False

A helium tank holds a volume of .02 m^3 at a pressure of 15.5*10^6 Pa and a temperature of 293 K. How many spherical balloons wi
lukranit [14]

Answer:

Explanation:

We shall find the volume of stored gas at atmospheric pressure .

P₁ V₁ = P₂ V₂

15.5 x 10⁶ x .02 = 10⁵ x V₂  ( atmospheric pressure is 10⁵ Pa )

V₂ = 3.1 m³

volume of one balloon = 4/3 x π r³ , r is radius of balloon

= 4/3  π x .11³

= .050658 m³

no of balloon = total volume to be filled / volume of one balloon

= 3.1 / .050658

= 61 .2

= 61

a satellite with a mass of 1800 kg is placed at an altitude of 594 km above the surface of Europa. What is the strength of the g
saul85 [17]
The formula for gravitational potential energy is Ep= mgh. Lets convert 594 km into m: 594 x 1,000 = 594,000 m. So we do: Ep= (1,800kg)(9.8N/kg)(594,000m) = (17,640N)(594,000) = 10,478,160,000 J.
