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.

Answer:

The car travels the distance of 225m before coming to rest.

Explanation:

v = 45m/s

t = 5s

Therefore,

d = v*t

= 45*5

= 225m

Is there proof of the existence of God and Satan?If so what proof?

ivolga24 [154]

Religiously it has been proved that God exist and even satan exist
scientist does not believe God exist.The big bang theory is a theory that postulated that a big bang occur when and everything but my proverb says "in a film there is always behind the scene" if God doesnt exist who created mountains,hills,rivers,oceans,man,animal,spirit and if satan doesnt exist why does hell exist but if God doesnt exist why is it in grammar law to use capital letter for God
but my advise for you is to ask God to show you if He truly exist

Rocks A and B are located at the same height on top of a hill. The mass of rock A is twice the mass of rock B. How does the pote

Ronch [10]

Potential energy is defined by formula

$U = mgh$

here

m = mass

g = acceleration due to gravity

h = height

Now here two different stones are located at same height

while mass of stone A is twice that of stone B

so here we can say potential energy of A is

$U_a = (2m)gh$

Similarly potential energy of B is

$U_b = mgh$

now if we take the ratio of two energy

$\frac{U_a}{U_b} = 2$

so we can say potential energy of stone A is two times the potential energy of B
