40 million
1. Approximately how many people watch the March Madness tournament? There are more than 140 million that watch March Madness.
Answer:
Its the biggest terrestrial planet as the result of the interior being not able to cool down that much.
its rotates rapidly
Explanation:
the earth planet is not close to the sun,which puts it in the advantage of not loosing water.
Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.
An object<span> with twice as much mass will exert twice as much </span>gravitational<span> pull on other </span>objects<span>. The </span>gravitational<span> force increases as the size of an </span>object<span>increases. On the other hand, the strength of </span>gravity<span> is inversely </span>related<span> to the square of the distance between two </span>objects<span>.</span>
Answer:
The change in the internal energy of the gas 1,595 J
Explanation:
The first law of thermodynamics establishes that in an isolated system energy is neither created nor destroyed, but undergoes transformations; If mechanical work is applied to a system, its internal energy varies; If the system is not isolated, part of the energy is transformed into heat that can leave or enter the system; and finally an isolated system is an adiabatic system (heat can neither enter nor exit, so no heat transfer takes place.)
This is summarized in the expression:
ΔU= Q - W
where the heat absorbed and the work done by the system on the environment are considered positive.
Taking these considerations into account, in this case:
- Q= 500 cal= 2,092 J (being 1 cal=4.184 J)
Replacing:
ΔU= 2,092 J - 500 J
ΔU= 1,592 J whose closest answer is 1,595 J
<u><em>The change in the internal energy of the gas 1,595 J
