Inequalities are mathematical expressions that include more than one mathematical value for which they are true. In this case, all temperatures greater than the boiling point of water are satisfactory for the expression. The boiling point of water is 100 °C, so the inequality becomes:
t > 100 °C
Different explanations that lead to the same result
-You need to substract the number of protons from the mass number.
-Mass number - atomic number= number of protons
-Following this equation:
CARBON
atomic number= 6
mass number= 12
mass number= protons + neutrons
12= 6 + x
x= 12-6
x= 6
Answer:
4 is the best answer but incomplete.
Explanation:
Heat from the Earth is also radiated back into space. The in and out of energy is what makes it an open system.
The answer is A. Most galaxies appear to be moving away from each other. Scientists discovered this when looking through very expensive microscopes, and saw that the universe was always growing and expanding, as if exploding from one point and moving outward.
