Answer: Atmosphere can be broadly divided into four distinct layers based on their altitude and temperature.

These layers are- Troposphere, Stratosphere, Mesosphere, and Thermosphere.

1) Troposphere ( extends upto 18 km from earth surface)- a layer that is closest to the surface of earth. It is called zone of weather as all the weather phenomenon ( such as storm, wind, precipitation, formation of clouds) occur in this layer. Temperature decreases with altitude in this layer.

2) Stratosphere (extends from 18 km to 50 km) - a layer above troposphere, where temperature increases with increase in altitude.

A boundary between stratosphere and mesosphere where temperature remains constant as elevation increases  is called Stratopause.

3) Mesosphere (extends 50 km upto 85 km) - a layer above stratosphere, where temperature decreases with increase in altitude.

A boundary between mesosphere and thermosphere, where temperature remains constant as elevation increases  is called Mesopause.

4) Thermosphere (extends from 85 km upto 600 km)-  a layer above mesosphere, where temperature again increases with increase in altitude. It is an extremely hot layer because of absorption of X rays and UV rays.

Thus, correct match for the question is-  

Troposphere -A) Layer closest to the Earth where all weather occurs.

Mesosphere- E) begins between 50-60km and decreases in temperature as elevation increases.

Mesopause- C) temperature remains constant as elevation increases.

Stratosphere -B) temperature increases as elevation increases.

Stratopause -D) temperature remains at a constant zero degrees Celsius as elevation increases.

A pressure that will support a column of Hg to a height of 256 mm would support a column of water to what height? The density of
Paul [167]

Answer:

<em>The height of water in the column = 348.14 cm</em>

Explanation:

<em>Pressure:</em><em>This is defined as the ratio of the force acting normally ( perpendicular) to the area of surface in contact. The S.I unit of  pressure is N/m²</em>

<em>p = Dgh............... Equation 1</em>

<em>Where p = pressure, D = density, g = acceleration due to gravity, h = height.</em>

<em>From the question, the same pressure will support the column of mercury and water.</em>

<em>p₁ = p₂</em>

<em>Where p₁ = pressure of mercury, p₂ = pressure of water</em>

D₁gh₁ = D₂gh₂.................. Equation 2

making h₂ the subject of equation 2

h₂ = D₁gh/D₂g............... Equation 3

Where D₁ and D₂ = Density of mercury and water respectively, h₁ and h₂ = height of mercury and water respectively

Given: D₁ = 13.6 g/cm³, D₂ = 1.00 g/cm³, h₁ = 256 mm = 25.6 cm.

Constant: g = 9.8 m/s²

Substituting these values into Equation 3,

h₂ = (13.6×9.8×25.6)/1×9.8

<em>h₂ = 348.14 cm</em>

<em>The height of water in the column = 348.14 cm</em>

uranmaximum [27]

Answer:

V = 10.88 m/s

Explanation:

V_i =initial velocity = 0m/s

a= acceleration= gsinθ-\mu_kcosθ

putting values we get

a= 9.8sin25-0.2cos25= 2.4 m/s^2

v_f= final velocity and d= displacement along the inclined plane = 10.4 m

using the equation

v^2_f=v^2_i-2as

v^2_f=0^2-2(2.4)(10.4)

v_f= 7.04 m/s

let the speed just before she lands be "V"

using conservation of energy

KE + PE at the edge of cliff = KE at bottom of cliff

(0.5) m V_f^2 + mgh = (0.5) m V^2

V^2 = V_f^2 + 2gh

V^2 = 7.04^2 + 2 x 9.8 x 3.5

V = 10.88 m/s
