1 answer:

3 0

Copernicus- developed heliocentric model, discovered the chemical element Copernicum has the symbol Cn and atomic number 112, started the scientific revolution.

Brahe- known for his precise and comprehensive astronomical and planetary observations, which heavily influenced future discoveries; built the maps of Hven that helps in accurate determinations of latitude and longitude.

Kepler - solved the mystery of the planets; believed the Solar System's planets orbited the sun in circular path that determined by an arrangement of the five platonic solids.

Galileo - Father of Modern Science; discovered the first moons ever known to orbit a planet other than Earth; first person to study the sky with a telescope; discovered the rings of Saturn; our moon has mountains; Milky Way is made up of stars; established that everything falls to the ground at the same rate regardless of weight; identified the parabola; proposed theory of relativity; discovered pendulums; tried to measure the speed of light; showed the set of perfect squares.

Newton- generalized the binomial theorem; showed sunlight is made up of all the colors of the rainbow; discovered the law of gravitation; Laws of motion and calculus.

What features form when rocks bend?

bezimeni [28]

When the sedimentary layers of rocks are soft and under pressure they can be bent into curved structures called geosynclines. One theory is that heat partially melts the sedimentary layers of rocks allowing them to be bent into the curved shapes.

Hope this helps :)!

Phosphorus crystallizes in several different forms, one of which is a simple cube with an edge length of 238 pm. What is the den

algol13

<u>Answer:</u> The density of phosphorus is $3.81g/cm^3$

<u>Explanation:</u>

To calculate the density of phosphorus, we use the equation:

$\rho=\frac{Z\times M}{N_{A}\times a^{3}}$

where,

$\rho$ = density

Z = number of atom in unit cell = 1 (CCP)

M = atomic mass of phosphorus = 31 g/mol

$N_{A}$ = Avogadro's number = $6.022\times 10^{23}$

a = edge length of unit cell = $238pm=238\times 10^{-10}cm$ (Conversion factor: $1cm=10^{10}pm$ )

Putting values in above equation, we get:

$\rho=\frac{1\times 31}{6.022\times 10^{23}\times (238\times 10^{-10})^3}\\\\\rho=3.81g/cm^3$

Hence, the density of phosphorus is $3.81g/cm^3$

The correct option is A.
The dependent variable is the variable that is measured during the experiment, it is the variable that is affected during the experiment. Experiments are design in such a way that the dependent variable depends on and respond to independent variable.
