What is the pressure at the bottom of a tank 1-m deep? Take the density of water to be 1000-kg/m^3, and gravitational accelerati
1 answer:
To solve this problem we will use the concepts related to hydrostatic pressure. Which determines the pressure of a body at a given depth of a liquid.
Mathematically this can be described as
Here
= Density
g = Gravity
h = Height (Depth)
If we replace the values given in the equation we will have to
Therefore the pressure at the bottom will be 9.8kPa

The longest wavelength of radiation used to break carbon-carbon bonds is 344 nm.
<u>Explanation:</u>
The longest wavelength of radiation can also be stated as the minimum radiation frequency required to cut carbon-carbon bond should be equal to the threshold energy of the carbon-carbon bonds.
The threshold energy will be equal to the binding energy of the carbon-carbon bonds. As it is known that carbon-carbon bonds exhibit a binding energy of 348 kJ/mole, the threshold energy to break it, is determined as followed.
First, we have to convert the energy from kJ/mol to J, i.e., energy for the carbon-carbon molecules,
As,
So,
Thus, is the longest wavelength of radiation used to break carbon-carbon bonds.

<h3>Briefing:</h3>Hydrogen has a spectral line at = 116nm=116×10⁻⁹m
Line is observed at = 107 nm=107×10⁻⁹m
Now, from the Hubble's law
V=×C
Where,
v is the velocity
Δλ = Change in wavelength = 116 - 107= 9nm=9×10⁻⁹m
λ = Actual wavelength=116nm=116×10⁻⁹m
C is the speed of the light=3×10⁸m/s
on substituting the respective values, we get
V=(9/116)×3×10⁸=23275862.069×10⁵m/s
V=2.3275862×10¹²km/s.
<h3>What is the wavelength?</h3>A waveform signal's wavelength, which is the distance between two identical locations (adjacent crests) in the succeeding cycles, determines whether it is sent through space or via a wire. Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimeters (mm).
