Answer:
Magma are the hot molten materials that rises up towards the surface due to the increasing force from the depth. These magma when comes out to the surface then they are considered as lava.
The felsic lava are those in which the amount of silica and aluminium is very high. Due to this high silica content, the viscosity is high. The amount of silica present in magma or lava is directly proportional to the viscosity of magma or lava. The felsic lava due to its high viscosity flows sluggishly.
Whereas, the basic lava are those in which the silica content is significantly less. Iron (Fe) and Magnesium (Mg) is mostly present in this type of lava. As a result of which it flows easily without any difficulty.
This is the reason why felsic magma (lava) are more viscous compared to the mafic magma (lava).
it is 10 because you have to set up an equation to get the answer

Answer:
When the 13 United States of America declared independence from the United Kingdom in 1776, the founders were attempting to break free from the tyranny of Britain’s top-down centralized government.
But the first constitution the founders created, the Articles of Confederation, vested almost all power in individual state legislatures and practically nothing in the national government. The result—political chaos and crippling debt—almost sunk the fledgling nation before it left the harbor.
So the founders met again in Philadelphia in 1787 and drafted a new Constitution grounded in a
novel separation of state and national powers known as federalism. While the word itself doesn’t appear anywhere in the Constitution, federalism became the guiding principle to safeguard Americans against King George III-style tyranny while providing a check against rogue states.
