How does American culture support individualism?

ser-zykov [4K]

The United States has one of the most individualistic cultures in the world. Americans are more likely to prioritize themselves over a group and they value independence and autonomy. This societal ethos can be seen in how Americans relate to each other–Americans do not tend to touch each other during interpersonal interactions. Americans maintain a greater distance of personal space between themselves and others, compared to more touch-oriented, collectivistic cultures like in Latin American or Mediterranean countries. As such, there is less physical contact and touch between friends, family, and strangers. Studies have revealed that touch increases social bonding and feelings of goodwill towards others. Touch, as a social-psychological phenomenon, is fundamentally linked to a culture’s level of individualism. Americans’ individualistic culture makes non-sexual, interpersonal touch less frequent. However, the lack of touch–the distant, American way of interacting–also contributes to its individualistic culture, in a self-reinforcing cycle.

What is the temperature of 12.20 mol of gas in a 18.35 l tank at 16.40 atm? round your answer to the tenths place.

lys-0071 [83]

Based on the calculations, the temperature of this ideal gas is equal to 300.5 K.

<h3>How to calculate the temperature.</h3>

Mathematically, the temperature of an ideal gas is given by this formula:

$PV=nRT\\\\T=\frac{PV}{nR}$

<u>Where:</u>

P is the pressure.

R is the ideal gas constant.

T is the temperature.

n is the number of moles.

V is the volume.

<u>Given the following data:</u>

Number of moles = 12.20 moles.

Volume = 18.35 L.

Pressure = 16.40 atm.

Substituting the given parameters into the formula, we have;

$T=\frac{16.40 \times 18.35}{12.20 \times 0.0821}\\\\T=\frac{300.94}{1.00162}$

T = 300.5 K.

Factor the expression into an equivalent form 12y^2-75.

elena-14-01-66 [18.8K]

Hello oddworld7836!

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Factor the expression into an equivalent form 12y² - 75.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$12 y ^ { 2 } - 75$

By observing the expression, we can see that, 3 is the only common factor in both the terms of the expression. So, take the common factor 3 out.

$12 y ^ { 2 } - 75 \\ = 3\left(4y^{2}-25\right)$

Now, look at (4y² - 25). They don't have any common factors but they appear in the form of the algebraic identity ⇨ a² - b² = (a + b) (a - b). Here,

a² = 4, a = 2 (√a² = ✓4 = 2)
b² = 25, b = 5 (√b² = ✓25 = 5)

So, the (4y² + 25) becomes...

$(4 {y}^{2} - 25) \\ = \left(2y-5\right)\left(2y+5\right)$

Now, bring the 3 (common factor) & rewrite the complete expression.

$12 y ^ { 2 } - 75 \\ = \boxed{ \boxed{ \bf \: 3\left(2y-5\right)\left(2y+5\right) }}$

We can't further simplify it. Also, remember that the simplified form of an expression is equivalent to the expression. So, 3 (2y - 5) (2y + 5) is equivalent to 12y² - 75.
