Answer:

\boxed{\text{0.76m/s}}

Explanation:

\text{Average speed} = \dfrac{\text{total distance}}{\text{total time}}

Total distance = 2 m + 30 m = 32 m

      Total time = 2 s  + 40 s   = 42 s

\text{Average speed} = \dfrac{\text{32 m}}{\text{42 s}} = \textbf{0.76 m/s}\\\text{The average speed of the object is $\boxed{\textbf{0.76m/s}}$}

The complex [FeSCN]2+ has an absorptivity of 6.14×10−2 L/(mg⋅cm) at a wavelength of 580 nm. The transmittance of a solution samp
klio [65]

Answer:

4.36 ppm

Explanation:

First we convert percent transmittance to absorbance:

  • A = 2 - log(%T)
  • A = 0.268

Then we <u>calculate the concentration of the solution</u>, using <em>Lambert-Beer's equation</em>:

  • A = ε*l*C

It is usually used with molar concentrations but given that the given absortivity is in ppm terms and the answer is also in ppm, we can simply use the given value.

  • 0.268 = 6.14x10⁻²L·ppm⁻¹ * 1.00 cm * C
  • C = 4.36 ppm
