Describe the gases that are emitting from a volcanic eruption. What affect do they have on the atmosphere and planet?

1 answer:

8 0

The types of gas expelled from a volcanic eruption include water vapor (the most abundant of volcanic gas), carbon dioxide, hydrogen sulfide, hydrogen halides and sulfur dioxide. When volcanoes erupt, they have a negative effect on the atmosphere and planet because all of the gases emitted (except water vapor) are hazardous to people, animals, plants, and property. These gases can add to the Greenhouse Effect by causing an increase in temperature. Some particles such as ash and sulfur dioxide act as an exact opposite by creating a cooling effect, reflecting sunlight away from Earth. There is also evidence that proves these eruptions can affect short-term weather.

What factors affect the chemical properties of seawater

Nady [450]

An ocean's salinity is affected by water and air temperature, the volume of water that flows into it, its age and the chemical composition of surrounding geological formations.<span> Because the effect of these factors varies over the area of an ocean, different levels are found within the ocean</span>

Throughout the problem, take the speed of sound in air to be 343 m/s . Part A Consider a pipe of length 80.0 cm open at both end

White raven [17]

Answer:

the lowest frequency f of the sound wave is 214.375 Hz

Explanation:

The computation of the lowest frequency f of the sound wave is shown below;

Length = L= 80 cm

= 0.8 m

V = 343 m/s (sound speed in air )

Now

V1 = n V ÷ 2 L

= 1 × 343 ÷ 2 × 0.8

V1 = 214.375 Hz

Hence, the lowest frequency f of the sound wave is 214.375 Hz

We simply applied the above formula so that the correct value could come

And, the same is to be considered

A planet orbits a star, in a year of length 2.35 x 107 s, in a nearly circular orbit of radius 3.49 x 1011 m. With respect to th

Naya [18.7K]

Answer:

a) w = 9.599 10⁴ rad / s , b) v = 3.35 10¹⁶ m / s , c) a = 3.22 10²¹ m / s²

Explanation:

For this exercise we must use the relation of angular kinematics

a) angular velocity, the distance remembered in orbit between time (period)

w = 2π r / T

w = 2 π 3.59 10¹¹ / 2.35 10⁷

w = 9.599 10⁴ rad / s

b) linear and angular velocity are related by the equation

v = w r

v = 9,599 10⁴ 3.49 10¹¹

v = 3.35 10¹⁶ m / s

c) the centripetal acceleration is

a = v² / r = w² r

a = (9,599 10⁴)² 3.49 10¹¹

a = 3.22 10²¹ m / s²

A snowball that will be used to build a snowman is at the top of a only hill. If the

Darina [25.2K]

Answer:

h = 24.11 m

Explanation:

Given that,

The potential energy of the snowball is 520 J

The mass of the snowball is 2.2 kg

We need to find the height of the hill. The potential energy of an object is given by the formula as follows :

$E=mgh$

g is acceleration due to gravity

h is height of the hill

$h=\dfrac{E}{mg}\\\\h=\dfrac{520}{2.2\times 9.8}\\\\h=24.11\ m$

So, the height of the hill is 24.11 m.

What is the time lapse between seeing a lightning strike and hearing the thunder if the lightning flash is 47 km away? The speed

Natali5045456 [20]

Answer:

141.14098 secs

Explanation:

Time taken to see the lightning flash can be gotten from:

Velocity = distance/time

Time = distance/velocity

Time = (47 * 1000)/(3 * 10^8)

Time = 0.0001567 secs

Time taken to hear the thunder can be gotten from:

Velocity = distance/time

Time = distance/velocity

Time = (47 * 1000)/(333)

Time = 141.14114 secs

The time lapse between the lightning flash and the thunder will be:

141.14114 - 0. 0001567

= 141.14098 secs
