Does the reference point selected for the properties of a substance have any effect on thermodynamic analysis? Why?
MrMuchimi

Answer:

No, the reference point selected for the properties of a substance does't have any effect on thermodynamic analysis.

Step-by-step explanation:

Consider the provided information.

We need to determine that the reference point selected for the properties of a substance have any effect on thermodynamic analysis.

The answer for this question is No.

The reference point selected for the properties of a substance does't have any effect on thermodynamic analysis.

Because in thermodynamic analysis we are deal with the change in the properties.

If we are doing calculation, the reference state chosen is irrelevant as long as we use values in a single consistent array of tables and charts.

Hence, The reference point selected for the properties of a substance does't have any effect on thermodynamic analysis.

Find the area, in square feet, of a triangle whose base is 42⁄3 feet and whose altitude is 84⁄7 feet. A. 135⁄21 B. 20 C. 40 D. 2
CaHeK987 [17]

Answer:

Option B. 20\ ft^{2}

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=\frac{1}{2}bh

we have

b=4\frac{2}{3}\ ft

h=8\frac{4}{7}\ ft

Convert mixed numbers to an improper fractions

b=4\frac{2}{3}\ ft=\frac{4*3+2}{3}=\frac{14}{3}\ ft

h=8\frac{4}{7}\ ft=\frac{8*7+4}{7}=\frac{60}{7}\ ft

substitute the values

A=\frac{1}{2}(\frac{14}{3})(\frac{60}{7})\\ \\A=\frac{14*60}{2*3*7}\\ \\A=\frac{840}{42} \\ \\A=20\ ft^{2}

Tristan is building steps up to a deck that is 156 5 6 yards above the ground. The steps must all be the same height. If he want
ss7ja [257]

Answer:

The height of each step is 1957 yard

Step-by-step explanation:

we are given

Tristan is building steps up to a deck that is 15656 yards above the ground

so, total height =15656 yards

Number of steps =8

now, we can use formula

Height of each step = ( total height)/( number of steps)

now, we can plug these values

and we get

Height of each step is

=\frac{15656}{8}yards

=1957yards
