Answer:

The correct answer is Troposphere.

Explanation:

The troposphere is the closest atmospheric layer of the earth's surface and 80% of the total mass of the atmosphere and 99% of the water vapor are located here.

In this layer, the higher the altitude, the temperature and the steam will be lower. This steam is responsible for regulating air temperatures thanks to the absorption of energy from the sun. <u>Here is the air we breathe and all the climatic processes of our planet. </u>

80% of the mass of the atmosphere is located in this layer because in it the air is much denser than in the other layers.

Answer:

The angular distance in revolution is $revolution = 3.439 \ revolution$

The angular distance in radians is $\theta_{rad}= 21.6 \ radians$

The angular distance in degrees is $\theta =1238.04^o$

The angular size is $Z = \frac{2}{9} \pi \ radians$

Explanation:

From the question we are told that

The diameter is $d = 10 \ inches$

The distance moved by the rim is $D = 108 \ inches$

Generally the circumference of the pie plate is mathematically represented as

$C = \pi d$

Substituting the values

$C = 10 *3.142$

$= 31.42 \ inches$

The number resolution carried out by the pie plate is evaluated as

$revolution = \frac{D}{C}$

Substituting value

$revolution = \frac{108}{31.4}$

$revolution = 3.439 \ revolution$

The angular distance $\theta_{rad}$ is mathematically evaluated as

$\theta_{rad} = \frac{D}{r}$

Where r is the radius which is mathematically evaluated as

$r = \frac{d}{2} = \frac{10}{2} = 5 \ inches$

Substituting this into the equation for angular distance

$\theta_{rad} = \frac{108}{5}$

$\theta_{rad}= 21.6 \ radians$

The angular distance traveled in degrees is

$\theta = 3.439 *360$

$\theta =1238.04^o$

When the pie is cut into 9 equal parts

The angular size would be mathematically evaluated as

$Z = \frac{2\pi}{9}$

$Z = \frac{2}{9} \pi \ radians$

What mistake did Kamala make? Gamma rays should have a very high frequency, not a very low frequency. Visible light should have

olasank [31]

Answer:

The answer is "Option A".

Explanation:

Please find the complete question in the attached file.

Kamala uses Gamma radiation inside this question should be very high, not very low. Electromagnetic radiation is a penetrating type resulting from radioactive nuclear decline. Its radiation is a very high-frequency, radioactive waveform to frequencies greater than $10^{19} \ Hz$ usually emitted from the radioactive decline.

lukranit [14]

Answer:

Explanation:

Let the time required for acceleration a₁ and deceleration a₂ be t₁ and t₂ .

Since final velocity during acceleration and initial velocity during deceleration are same

a₁ t₁ = a₂ t₂

5t₁ = 2 t₂ ------------------------------------------ ( 1 )

Distance travelled during acceleration = 1/2 a₁t₁²

= 1/2 x 5 x t₁² = 2.5 t₁²

Distance travelled during deceleration = 1/2 a₂t₂²

= 1/2 x 2 x t₂² = t₂²

Total distance travelled = 2 miles = 2 x 1760 x 3 ft = 10560

2.5 t₁² + t₂² = 10560

2.5 ( 2t₂ / 5 )² + t₂² = 10560

.4 t₂² + t₂² = 10560

1.4 t₂² = 10560

t₂ = 86.85 s

t₁ = 2t₂ / 5 = 34.75 s

t₁ + t₂ = 121.6 = 122 s

Total time taken = 122 s .

maximum velocity = a₁t₁

= 5 x 34.75 = 173.75 = 174 m/s .
