Which of these is a rough approximation of the cogito?

ratelena [41]

Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase "I think, therefore I am".

Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to Rene Descartes. This Latin phrase is roughly translated as "I think, therefore I am", which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

What volume in liters will be occupied by 1.20 moles of helium gas at a pressure of 3.675 atm and 100*C?

lesya [120]

Answer:

V = 121.82 L

Explanation:

Given data:

Number of moles of gas = 1.20 mol

Pressure of gas = 3.675 atm

Temperature = 100°C

Volume occupied = ?

Solution:

Formula:

General gas equation:

PV = nRT

R = general gas constant.

Now we will convert the temperature into kelvin.

100+273 = 373 K

V = nRT/P

V = 1.2 mol × 0.0821 atm.L/mol.K × 373 K / 3.675 atm

V = 447.68 / 3.675 atm

V = 121.82 L

The p-value of a statistical test depends on all of the following, except:

vaieri [72.5K]

Answer:

The correct option is e.

Explanation:

p-value is the probability value for a given statistical model, the probability that, when the null hypothesis is true.

For two two samples the formula of test statistics is

$t=\frac{(\overline{x}_1-\overline{x}_2)-(\mu_1-\mu_2)}{\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}}$

where,

$\overline{x}$ is sample mean

$\mu$ is population mean.

$s$ is standard deviation.

n is sample size.

Variance is the square of standard deviation.

It means variance, mean, numbers of samples is used in calculation of p-value.

Degree of freedom define the shape of the t-distribution that your t-test uses to calculate the p-value.

$d.f.=n_1+n_2-2$

p-value of a statistical test depends on all of the following, except median.

Therefore the correct option is e.

Explain Charles law

kodGreya [7K]

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

Explanation:

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at $0^{\circ} \mathrm{C}$ for each one degree rise or fall in temperature”. Formula derived from law is as follows: $\mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}]$ here ${V}_{0}$ is volume of given mass of a gas at $0^{\circ} \mathrm{C}$ , ${V}_{t}$ is its volume at any temperature $t^{\circ} \mathrm{C}$ . Application of Charles law is hot air balloons.
