Answer:

8.99×10^-7m

Explanation:

The wavelength can be calculated using the expression below

E=hcλ

Where E= energy= 2.21 x 10^-19 J.

C= speed of light= 3x10^8 m/s

h= planks constant= 6.626 × 10^-34 m2 kg / s

E=hcλ

λ= E/(hc)

Substitute for the values

λ=( 2.21 x 10^-19 )/(6.626 × 10^-34 × 3x10^8 )

= 8.99×10^-7m

How do engineers evaluate potential solutions to complex<br> problems?
loris [4]

Answer:

  1. Break down a problem into smaller units or sub-problems.
  2. Reverse engineering, or taking something apart so as to evaluate and provide solutions.

Explanation:

For the first one, if you are a computer engineer for example, it is hard to troubleshoot a whole program but if you write small stand alone sections, you can easily troubleshoot the smaller section.

koban [17]
1. According to Rutherford and soddy's law of Beta emission:

{K}^{42} \: ---> {Ca}^{40} + {2e}^{0}

3. According to Rutherford and soddy's law of Alpha emission:

{U}^{238} \: ---> {Th}^{234} + {He}^{4}

4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
