Since prehistoric times what has been the correlation between atmospheric carbon dioxide level and global temperature

Physics

Answer:

The correlation based on one source of estimates of temperatures and CO2 levels (namely the Vostok data) is <em>positive</em> with an R^2 coefficient of about 0.75.

Explanation

There are only few sources of data for us to estimate this correlation over long periods of time. One of these are the "Vostok" ice core data that span some 400 thousand years of estimated temperature and CO2 levels (https://cdiac.ess-dive.lbl.gov/trends/co2/vostok.html). A paper referenced below shows the coefficient of determination of 0.75.

It should be pointed out that a correlation, and even more so causality between historical CO2 and temperatures has been subject of an ongoing scientific debate. This debate is further compounded by politically motivated factors. So it remains to be added: use care adopting conclusions of others in this active field of science, try to perform own analysis of raw/original sources yourself, whenever possible.

const2013 [10]

Answer:

6,600N

Explanation:

According to second law of motion, Force = mass × acceleration

If acceleration = change in velocity/time = 15/0.10

Acceleration = 150m/s²

Given mass = 44kg

Force = 44× 150

Force = 6,600N

Magnitude of the average force exerted on the passenger during this time is 6,600N

Determine the empirical formula for a compound that is 36.86% n and 63.14% o by mass.
olga2289 [7]

Answer:

NO_{1.499}

Explanation:

Let assume that 100 kg of the compound is tested. The quantity of kilomoles for each element are, respectively:

n_{N} = \frac{36.86\,kg}{14.006\,\frac{kg}{kmol} }

n_{N} = 2.632\,kmol

n_{O} = \frac{63.14\,kg}{15.999\,\frac{kg}{kmol} }

n_{O} = 3.946\,kmol

Ratio of kilomoles oxygen to kilomole nitrogen is:

n^{*} = \frac{3.946\,kmol}{2.632\,kmol}

n^{*}= 1.499

It means that exists 1.499 kilomole oxygen for each kilomole nitrogen.

The empirical formula for the compound is:

NO_{1.499}
