It's some risky to say "the best one" in general. The best one for what? (environment, cost availability, sustainability, easy access, usability, storage feasability,,,) Solar seems the best for individual buildings (eventually combined with geothermal). Wind is OK for distribution, but generators should not occupy land instead of trees (neither solar panels should), not fil up the seas and kill birds, mess up landscape, etc, Hydraulic has been sinds many time a good sustainable solution but is limited and only possible in countries with mountains, like Norway, Switzerland... Also generating power from seawaves. Not all biofuels are sustainable: they must have a sustainable origin.

Hope it helps you

use the pendulum equation to calcuate the period of a 1.50 pendulum. Remeber that the vaule of "g" is 9.81 m/s² please help ​
kati45 [8]

Answer:

L = 3.51

Explanation:

Pendulum equation is T = 2pi\sqrt{L/9.81}

T = 1.5 and we are solving for L

1.5=2\pi \sqrt{L/9.81}

square both sides to get 2.25 = 2\pi ( L/9.81)

multiply both sides by 9.81 then divide by 2 and 3.14 as a substitue for pi. The answer should be about 3.51 in length

L = 3.51

What is the thinnest film of a coating with n = 1.39 on glass (n=1.52) for which destructive interference of the red component (
Illusion [34]
In optics, you have to create a layer of coating that is approximately 1/4 of the light's wavelength. The working equation for this problem is:

d = λ₀/4n, 
where
λ₀ is the wavelength of the incident light
n is the refractive index of the coating

Substituting the values,

d = (650 nm)/4(1.39)
<em>d = 116.9 nm</em>
