Answer:
5.131 × 10¹⁴ Hz
Step-by-step explanation:
<u>Planck relation</u>

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:






Answer:

The volume of the box is 41.21 inches cube.
Answer:
1) 36 yard
2) 2 feet
Step-by-step explanation:
1) Perimeter = 4 * side length
144 = 4 * s
s = 36
2) Area = Length * Length
4 = l * l
l = 2
