The impact of the heavy stone would produce waves with a higher amplitude because the stone would pick up more speed while falling.
Answer:
Freeze Fracture replication
Explanation:
<u>Freeze Fracture replication</u> is a technique that allows investigation of the microheterogeneity of a membrane so that one can see localized differences in different parts of the membrane.
Freeze fracture replication is a technique used with electron microscopy to splits frozen cell membranes apart for visualization of the membrane structure and the organization of proteins within the sea of phospholipids.
The four steps in making a freeze-fracture replication are
(i) rapid freezing,
(ii) fracturing,
(iii) replication and
(iv) replica cleaning.
Answer:
a) f = 809.5 Hz
, b) f = 1619 Hz
Explanation:
The condition for destructive interference from the speakers is
Δr / lam = Ф / 2π
λ = Δr 2π / π
We substitute
λ = 0.21 2 π/π
Lam = 0.42 m
Now let's use the ratio of the speed of sound and the wavelength and the frequency
v = λ f
f = v /λ
f = 340 / 0.42
f = 809.5 Hz
b) in this case the intensity is maximum
Lam = Δr 2π / 2π
Lam = 0.21 m
fF= v / lam
f = 340 / 0.21
f = 1619 Hz
Answer:
Vertical -- angle --- horizontal
Explanation:
The intensity transmitted by a polarized is given by the expression
I = I₀ cos² θ
Where tes is the angle between the polarization of light and the direction of polarization.
From this expression it is observed that if the angle is zero (parallel) the transmission is maximum and if in the angle it is 90 ° (perpendicular) the transmission is zero.
With these arguments we will analyze the three polarizers placements.
The light has an initial vertical polarization, so that the first possible polarizer is transmitted, it must be parallel, bone with vertical polarization
It is second polarizer must have some angle so that the light that comes out has vertical and horizontal polarization
Finally, the third polarizer must be horizontal for the horizontal second polarizer component to be transmitted.
Consequently the order is
Vertical -- angle --- horizontal
