Plot the absorbance, A, versus the FeSCN2 concentration of the standard solutions (the values from your Pre-lab assignment). Fro

m this calibration curve, determine the concentration of FeSCN2 in each of the equilibrium solutions you prepared using their absorbance values. You should use the program Excel and the LINEST function to plot and analyze this data. You should report 6 values for [FeSCN2 ]eq.

As the amplitude decreases in a wave the energy increasesTrue or false
Montano1993 [528]

Answer:

True

Explanation:

To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

**Please Help, ASAP**
Novay_Z [31]

Explanation:

We need to rearrange the following formula for the values given in parenthesis.

(1) x+xy = y, (x)

taking x common in LHS,

x(1+y)=y

x=\dfrac{y}{1+y}

(2) x+y = xy, (x)

Subrtacting both sides by xy.

x+y-xy = xy-xy

x+y-xy = 0

x-xy=-y

x(1-y)=-y

x=\dfrac{-y}{1-y}

(3) x = y+xy, (x)

Subrating both sides by xy

x-xy = y+xy-xy

x(1-y)=y

x=\dfrac{y}{1-y}

(4) E = (1/2)mv^2-(1/2)mu^2, (u)

Subtracting both sides by (1/2)mv^2

E-(1/2)mv^2 = (1/2)mv^2-(1/2)mu^2-(1/2)mv^2

E-(1/2)mv^2 =-(1/2)mu^2

So,

2(E-\dfrac{1}{2}mv^2)=-mu^2\\\\u^2=\dfrac{-2}{m}(E-\dfrac{1}{2}mv^2)\\\\u=\sqrt{\dfrac{-2}{m}(E-\dfrac{1}{2}mv^2)}\\\\u=\sqrt{\dfrac{2}{m}(\dfrac{1}{2}mv^2-E)}

(5) (x^2/a^2)-(y^2/b^2) = 1, (y)

\dfrac{x^2}{a^2}-1=\dfrac{y^2}{b^2}\\\\y^2=b^2(\dfrac{x^2}{a^2}-1)\\\\y=b\sqrt{\dfrac{x^2}{a^2}-1}

(6) ay^2 = x^3, (y)

y^2=\dfrac{x^3}{a}\\\\y=\sqrt{\dfrac{x^3}{a}}

Hence, this is the required solution.

How Does A Shoe Box Solar Cooker Work?
Natalija [7]

Answer:

the sun gives off light while at the same time gives off heat. the shoe box cooker takes that heat and light and reflects it around the shoe box. then the heat settles down into whatever is in the shoe box. the heat after being reflected around the shoe box is magnified by the foil wrapped in the box thus allowing the food or drink to be heated. the foil is a conductor of heat because it is metal .

Explanation:

hope this helps!

Technician A says that the B-pillars aid in resisting roof crush.
Andreyy89

Answer:

The answer is "Both A and B" are right

Explanation:

During the previous twenty years car producers have made significant advances in planning vehicle structures that give more noteworthy tenant insurance in planar accidents (Lund and Nolan 2003). Be that as it may, there has been little agreement with respect to the significance of rooftop strength in rollover crashes, just as the best strategy for surveying that strength. In 2006 one-fourth of lethally harmed traveler vehicle tenants were associated with crashes where vehicle rollover was considered the most hurtful occasion (Protection Establishment for Expressway Wellbeing, 2007). Numerous lethally harmed tenants in rollovers are unbelted, and some are totally or mostly launched out from the vehicle (Deutermann 2002).

There is difference concerning how underlying changes could influence launch hazard or the danger of injury for inhabitants who stay in the vehicle, paying little mind to belt use.
