What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

Planck relation

$\large\boxed{E = hf}$

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.) ex 5 ex dx.

melisa1 [442]

Answer:

$5 e^{x} +C$

where C is constant of integration

Step-by-step explanation:

Explanation:-

Given f(x) = 5 eˣ

Now integrating with respective to 'x' , we get

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

By using integration formula

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

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

where C is constant of integration
