<h3>Answer:</h3>
  • E≈2,5 eV
<h3>Explanation:</h3>

_______________

λ=500 nm = 500·10⁻⁹ m

c=3·10⁸ m/s

h=6,63·10⁻³⁴ J·s = 4,14·10⁻¹⁵ eV·s

_______________

E - ?

_______________

\displaystyle \boldsymbol{E}=h\nu =h \frac{c}{\lambda} =4,14\cdot 10^{-15} \; eV\cdot s\cdot \; \frac{3\cdot 10^8\; m/s}{500\cdot 10^{-9}\; m} =2,484\;  eV\approx \boldsymbol{2,5\; eV}

One carpenter builds 1/5 of a house in 3/4 of a day and the other builds 2/5 of a house in the same amount of time. How many hou
AlladinOne [14]

Answer:

4/5 houses

Explanation:

The speed of the first carpenter is:

(1/5 house) / (3/4 day) = 4/15 house/day

The speed of the second carpenter is:

(2/5 house) / (3/4 day) = 8/15 house/day

Together, their combined speed is:

4/15 house/day + 8/15 house/day = 12/15 house/day

= 4/5 house/day

Per day, the two carpenters build 4/5 of a house.
