A scientific probe is a device that is sent to gather information from areas with harsh or dangerous conditions so as to not endanger humans. such devices may be sent to the sea floor, into a volcano, or into space. they collect information on those areas such as pressure, temperature, and makeup of the environment and send that information back to scientists so that they can evaluate and record that collected data.
Answer:
the correct one is: a diffraction limits the resolving power to approximately the size of the wavelength of the light used
Explanation:
To be able to solve two structures with a light source, the Rayleigh criterion must be met that stable the two structures are solved when the first minimum of diffraction at one point is in the code of the first maximum of the other point
Using this criterion we can find an expression for the first minimization of the diffraction spectrum m = 1
sin θ tea = λ / a
now the structure of the comatose has a separation of around 1 nm and the wavelength of visible light ranges from 400 to 700 nm, when substituting we find
sin θ = 400/1 10
sin θ = 400
sin θ = 700/1
sin θ = 700
These values are neither impossible since the sin function is bounded between -1 to 1, so we cannot see the diffraction
When reviewing the different statements, the correct one is: a diffraction limits the resolving power to approximately the size of the wavelength of the light used:
Answer:
[OH⁻] = 1 × 10⁻¹¹ mol/dm³
Explanation:
Since the hydronium ion concentration of the gastric fluid is [H₃O]⁺ = 1.0 × 10⁻².
The pH at this point is pH = -log₁₀[H₃O]⁺ = -log₁₀[1.0 × 10⁻²] = 2
When milk of magnesia is added, the pH increases by one unit, so the new pH is 1 + 2 = 3
Since pH + pOH = 14, then pOH = 14 - pH = 14 - 3 = 11
The hydroxide ion concentration of the fluid is gotten from
pOH = -log₁₀[OH⁻]
11 = -log₁₀[OH⁻]
-11 = log₁₀[OH⁻]
taking antilog
[OH⁻] = 1 × 10⁻¹¹ mol/dm³
Answer:
solving for: velocity
equation: velocity = distance / time
substitution: velocity = 1425 km / 12.5 hrs
answer: 114 km/hr
The heat released or absorbed by a process where temperature changes is calculated from the product of the mass of the sample, its heat capacity (4.18 J/g C for water) and the change of the temperature.
Heat = mC(T)
Heat = 90 (4.8) (64) = 27648 J or 27.65 kJ needed
