Answer:
Explanation:This question is simply asking you to describe the following equations:
E = hv
v = c/L
E = hc/L
where E is the energy, h is Planck's constant, v is the frequency, c is the speed of light and L is the wavelength.
By looking at the equations you should be able to tell what the relationships between energy, frequency and wavelength are. If you are having difficulty describing them, then create a table with actual values and see what happens to the energy as you increase or decrease the frequency and/or wavelength.
Answer:
of the velocity of a full size plane in the air
Subatomic particles
Explanation:
Grand unification theory or GUT is a model that tries to describe the universe.
Answer: v = 6.0 m/s
Explanation:
T = m(v²/R - g)
(T/m + g)R = v²
v = √((79.0/0.98 + 9.81)0.40) = 6.0140... ≈ 6.0 m/s
Answer:
a) f₁ = 3.50 m
, b) f₂ = 0.84 m
Explanation:
For this exercise we must use the constructor equation
1 / f = 1 / p + 1 / q
where f is the focal length, p is the distance to the object and q is the distance to the image
a) the distance where the image should be placed is q = 3.50 m and the object is located at infinity p = ∞
1 / f₁ = 1 /∞ + 1 / 3.50
f₁ = 3.50 m
b) in this case the image is at q = -0.600 m and the object p = 0.350 m
1 / f₂ = 1 / 0.350 -1 / 0.600
the negative sign, is because the image is in front of the object
1 / f₂ = 1,1905
f₂ = 1 / 1,1905
f₂ = 0.84 m
