Answer:

Explanation:

Within each shell of an atom there are some combinations of orbitals. In the n=1 shell you only find s orbitals, in the n=2 shell, you have s and p orbitals, in the n=3 shell, you have s, p and d orbitals and in the n=4 up shells you find all four types of orbitals.

jek_recluse [69]

Answer:

A(n) <u>living wage</u> is the idea that people should be able to purchase the essentials of life by working a forty-hour workweek. Many local municipalities have as a result set higher minimum wages than the federally mandated minimum wage to accomplish this goal.

Explanation:

Living wage is the idea given to reduce poverty specially in cities with higher costs. It's based on the fact that one who works forty hours per week, he or she should be able to afford the basic needs of life that includes the water, food and shelter. Research has shown that the implementation of this concept has played the role in reducing poverty and enhancing the quality of life of workers. Countries like New-Zealand and united kingdom has supported this concept.

The water line from the street to my house is 1 inch diameter and made of PVC (i.e. smooth). The line is roughly 450 ft long. Th

jekas [21]

Answer:

The right solution is "126 Psi".

Explanation:

The given values are:

P₁ = 130 psig

i.e.,

= $130\times 6.894$

= $896.22 \ Kpa$

or,

= $896.22\times 10^3 \ Pa$

Z₂ = 10ft

= 3.05 m

$\delta$ = 1000 kg/m³

According to the question,

Z₁ = 0

V₁ = V₂

As we know,

⇒ $\frac{P_1}{\delta_g} +\frac{V_1^2}{2g} +Z_1=\frac{P_2}{\delta_g} +\frac{V_2^2}{2g} +Z_2$

On substituting the values, we get

⇒ $\frac{P_1}{\delta_g} +0+0=\frac{P_2}{\delta_g} +0+Z_2$

⇒ $\frac{896.22\times 10^3}{1000\times 9.8} =\frac{P_2}{1000\times 9.8} +3.05$

⇒ $P_2=866330 \ P_a$

i.e.,

⇒ $=866330\times 0.000145$

⇒ $=126 \ Psi$

A high-temperature gas is compared to the same gas at lower temperature. Which of the following statements is true?

ycow [4]

Answer:

I think it is C

Explanation:

If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.
