Answer:
Explanation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. Here follows the most common kinds of variation.
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. In the following equation y varies directly with x, and k is called the constant of variation:
y=kx
Another form of variation is the inverse variation which works when there is a relationship between two variables in which the product is a constant. When one variable increases the other decreases in proportion so that the product is unchanged.
Answer:
They each contributed to the development of the atomic theory
Explanation:
They each contributed to the development of the atomic theory. ... Bohr said there was no certain path for electrons, and in the current theory, the exact path cannot be predicted. But there is an electron cloud.
The chemical formula for steam is H2O(g)
mass of steam = mole of steam * molar mass of H2O
= 1 * (1*2+16) = 18 g
by E = m * c * change in temperature,
From 140C steam to 100C steam
18 * 2.01 * (140-100) = 1447.2J
latent heat of vaporization of water = 2.26x10^6 J/kg* 0.018 = 40680 J
From 100C water to 0C water
18 * 4.2 * (100-0) = 7560 J
latent heat of fusion of ice = 334 J/g * 18 g = 6012 J
From 0C ice to -45C ice
18 * 2.09 * (45-0)
= 1692.9 J
1447.2 + 40680 + 7560 + 6012 + 1692.9 = 57392.1 J
Answer:
I would go for number 5 . It sounds more logical to me.
An emerald can be described as a precious gemstone that is commonly green. However, emeralds can be other colors. Emerald commonly describes a color, such as emerald green eyes.
