What is the frequency of yellow
Zina [86]

Answer:

5.131 × 10¹⁴  Hz

Step-by-step explanation:

<u>Planck relation</u>

\large\boxed{E = hf}

where:

  • E = Energy of the photon (J).
  • h = Planck's constant (J · s).
  • f = frequency of light produced (Hz).

Given values:

  • E = 3.4 × 10⁻¹⁹ J
  • h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f

\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}

\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}

\implies f=0.5131\times 10^{(-19-(-34))}

\implies f=0.5131 \times 10^{15}

\implies f=5.131 \times 10^{14}

Evaluate the indefinite integral. (Use C for the constant of integration.) <br> ex 5 ex dx.
melisa1 [442]

Answer:

  5 e^{x} +C

where C is constant of integration

Step-by-step explanation:

<u><em>Explanation:-</em></u>

<em>Given f(x) = 5 eˣ</em>

Now integrating with respective to 'x' , we get

                                                      I =  \int\limits {5 e^{x} } \, d x

<em> By using integration formula</em>

                                       \int\limits { e^{x} } \, d x = e^{x} +C

                                     I =  \int\limits {5 e^{x} } \, d x  = 5 e^{x} +C

<em>where C is constant of integration</em>
