The answer iiiis...B: Column.

A column is a <em>vertical line, </em>while a row is a <em>horizontal line</em>. Elements in the same vertical line (or group, for fancy-science-talk), share similar properties. Since were looking for a vertical line, your answer would be B.

Answer:

1552.83J Released

Explanation:

1. mass/m=225

Initial temp:86C, final:32.5C

Changed Temp: 32.5-86= -53.5C

s=0.129 J/gC

Formula: q= m times s times changed Temp.

q=(225)(0.129)(-53.5)

q= -1552.83 J

q=1552.83 J Released

The pressure in car tires is often measured in pounds per square inch (lb/in.2), with the recommended pressure being in the rang

Mashutka [201]

Answer:

1.36 atm

Explanation:

First, we have to transform lb and in² into the International System of Units.

The international unit for force is the Newton. The equivalence (based on Earth's gravity) is 1 lb = 4.448 N.
The international unit for area is the m². The equivalence is 1 m² = 1550 in².
The resulting unit is known as Pascal. 1 Pa = 1 N/m².

$\frac{27.0lb}{in^{2}} .\frac{4.448N}{1lb} .\frac{1550in^{2}}{1m^{2} } =1.38 \times 10^{5} Pa$

The equivalence between Pascal and atm is 101,325 Pa = 1 atm. Then,

$1.38 \times 10^{5} Pa.\frac{1atm}{101,325Pa} =1.36atm$
