f = 7.4 x 10²⁰s⁻¹
Explanation:
Given parameters:
wavelength of light = 405 x 10⁻⁹m or 405nm
Unknown:
Frequency of light = ?
Solution:
We can solve this problem using the wave equation:
V = f∧
where V is the velocity of light = 3 x 10⁸m/s
f is the unknown frequency
∧ is the wavelength of light
making f the subject:
f = =
}{405 x 10
}[/tex]
f = 7.4 x 10²⁰s⁻¹

Answer:
9.0 g/cm³
Explanation:
Density can be computed with the formula:
Where:
D = Density
M = Mass
V = Volume
In your problem we are given:
84 cm³ = volume
760 g = mass
So we just plug in our given into the formula:
The answer would then be:
9.0 g/cm³
