The area of triangle ABC is _____.
Marizza181 [45]
I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 
SEE ATTACHED IMAGE.
 
Using Heron's Formula we can find the area of the triangle.
 A = root (s (s-a) * (s-b) * (s-c))
 s = (a + b + c) / 2
 Where,
 s: semi-perimeter
 a, b, c: sides of the triangle
 Substituting values:
 s = (15 + 16 + 20) / 2
 s = 25.5
 s = 26
 The area will be:
 A = root (26 * (26-15) * (26-16) * (26-20))
 A = 130.9961832
 A = 130 u ^ 2
 Answer:
 
The area of triangle ABC is:

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}
