Explanation:
Coal is chemically complex fuel. ... The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities. Today, many of the effects of coal burning have been reduced significantly or eliminated.
Answer:
d=2760,9m
Explanation:
<em>The gravitational force between two equal masses is defined as </em>
<em>F=G.m^2/d^2 where m is mass, G is the universal gravitation ( approximately= 6,67x10^-11N.m^2/kg^2) constant , F is the attractive (or repulsive) force and d is the distance between the masses. </em>
<em>Substitude the values of the quantities into the equation </em>
<em>d^2= G.m^2/F</em>
<em>d= 2760,9m</em>

Answer:
Hey there!
This is a convergent boundary. Here, a oceanic crust collides with a continental crust.
Hope this helps :)
The answer is : Magma with low viscosity. It makes for a weak volcanic eruption. <span>If the </span>viscosity<span> is </span>low (thin)<span>, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When </span>magma<span> reaches the surface of the earth, it is called lava. </span>
