how freezing could be used to remove sugar from a mixture of sugar and water.
what is the mineral salt
intake of chlorophytes
Explanation:
Microalgae can offer several benefits for wastewater treatment with their ability to produce large amounts of lipids for biofuel production and the high economic value of harvested biomass for biogas and fertilizer. This study found that salt concentration (∼ 45 g L⁻¹) had more of an effect than salt type on metabolisms of Chlorella vulgaris for wastewater treatment and biofuel production. Salinity stress decreased the algal growth rate in wastewater by 0.003 day⁻¹ per mS cm⁻¹ and slightly reduced nutrient removal rates. However, salinity stress was shown to increase total lipid content from 11.5% to 16.1% while also increasing the saturated portions of fatty acids in C. vulgaris. In addition, salinity increased the algal settling rate from 0.06 to 0.11 m day⁻¹ which could potentially reduce the cost of harvesting for algal biofuel production. Overall, C. vulgaris makes a suitable candidate for high salinity wastewater cultivation and biofuel production.

Answer:
kilogram metre per second square
a uniform metre scale rests horizontally on a knife edge at the 60cm mark when a mass of 10 gram is suspended from one end . at which end this mass be suspended . what is the mass of meter scale?
Answer:
40 gram or 0.04 kilogram
Explanation:
From the diagram attached,
The mass must be suspended at end B.
Applying the principle of moment,
Sum of clockwise moment = sum of anti-clockwise moment.
From the diagram,
Taking the moment about the pivot,
X(60-50) = 0.1(100-60)
Where X = weigth of the meter rule
10X = 4
X = 4/10
X = 0.4 N
X = 0.4/10
X = 0.04 kg
X = 40 g
Hence the mass of the meter rule = 0.04 kg or 40 gram

The illustration in figure below shows a uniform metre rule weighing 30 N pivoted on a wedge placed under the 40 cm mark and carrying a weight of 70 N hanging 2 from the 10 cm mark. The ruler is balanced horizontally by a weight W hanging from the 100 cm mark. Calculate the value of the weight W.
Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
[tex](70\ N)(40\ cm - 10\ cm)-(30\ N)(50\ cm-40\ cm)-(W)(100\ cm - 40\ cm) = 0\\W(60\ cm) = (70\ N)(30\ cm)-(30\ N)(10\ cm)\\\\W = \frac{1800\ N.cm}{60\ cm}[/tex]
W = 30 N

Answer:
[tex]L=11.3\ kg-m^2/s[/tex]
Explanation:
Given that,
Angular speed of a skater, [tex]\omega=3\ rot/s=18.84\ rad/s[/tex]
The moment of inertia of the skater, I = 0.6 kg-m²
We need to find the angular momentum of the skater. The formula for the angular momentum of the skater is given by :
[tex]L=I\omega[/tex]
Substitute all the values,
[tex]L=0.6\times 18.84\\\\L=11.3\ kg-m^2/s[/tex]

Eye at the lowest radiated power of 1,2 x10 x (- 17) W. Determine how many photons of light with a wavelength of 500nm fall on the retina of the eye every second
Answer:
[tex]\frac{n}{t} = 30\ photons/s[/tex]
Explanation:
The radiated power can be given in terms of the wavelength as follows:
[tex]Rasiated\ Power = \frac{nE}{t} = \frac{nhc}{\lambda t}[/tex]
where,
Radiated Power = 1.2 x 10⁻¹⁷ W
n = no. of photons = ?
h = plank's constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength = 500 nm = 5 x 10⁻⁷ m
t = time
Therefore,
[tex]1.2\ x\ 10^{-17}\ W = \frac{n(6.625\ x\ 10^{-34}\ J.s)(3\ x\ 10^8\ m/s)}{(5\ x\ 10^{-7}\ m)(t) }\\\\\frac{n}{t} = \frac{1.2\ x\ 10^{-17}\ W}{3.975\ x\ 10^{-19}\ J}\\\\\frac{n}{t} = 30\ photons/s[/tex]

Answer:
Heres the link!
Explanation:
https://www.bbc.co.uk/news/science-environment-56491033
Answer:
here's the link you asked for: https://www.nyas.org/ebriefings/the-physics-of-everything/ and here's the info inside the link: During the second quarter of 2016, the Academy hosted a series of evening panel discussions boldly titled "." With grant support from The John Templeton Foundation, the six panels addressed how physics is addressing grand questions and the potential limitations on what we may be able to learn using physics to address those questions.
The first session posed the question "" Three physicists explored the frontiers of cosmology and quantum physics. There may always be limits to our understanding in areas such as string theory, dark matter, and multiverses. But the panelists agreed that it is best to proceed as if explanations based in physics can be found.
The second session asked "" The panelists argued that philosophy has much to offer physics, in contrast to the assertions of some prominent physicists. In such areas as the role of observations in quantum mechanics and the experimental validation of theory, the panelists illustrated the power of a critical, interdisciplinary approach to understanding not only the facts but the significance of physics ideas.
Physics has achieved its success in part by selecting problems that can be addressed by reducing them to simple parts following simple laws. Less amenable subjects were discussed in the third session, "" Biology, ecology, and social phenomena such as cities are all not easily described with simple equations, but still show amazing regularities. The panelists, including two physicists, a philosopher, and a computer scientist, sketched their hopes for unifying principles that explain these regularities.
One complex phenomenon that has so far evaded physical analysis was the topic of the fourth session, "." Two of the panelists, a neuroscientist and a roboticist, did not even regard consciousness as a distinct phenomenon but rather as a byproduct of systems that model themselves. In contrast, a philosopher and a physicist felt that this behavioral description misses something essential about what consciousness "feels like." Both groups expressed hope for experimental tests of their views.
The fifth session addressed the question, "" Recent experimental observations of thousands of planets orbiting other stars bolster the expectation that ours is not the first civilization. The panelists explored how we might look for others and why we have not encountered any yet. One troubling possibility is that civilizations that achieve global scale inevitably encounter challenges such as climate change that they fail to overcome.
The sixth session was entitled "." Two physicists and a computer scientist discussed amazing developments at the intersection of quantum gravity (as manifested in black holes) and quantum information. Trying to reconcile these disparate observations has overturned the traditional view of black holes, with no clear resolution so far. At the same time, an abstract connection between gravitational models and quantum models in one fewer dimension is providing insight into both fields, including new methods for error correction in quantum computing as well as benchtop tests of black hole physics.
The wide ranging discussions of the six panels illustrate the power of physics to explain the universe as well as the vast frontiers of that universe that still remain to be explored.

A 50 KG girl on a swing is pushed with a net force of 200 N. What is the girl’s acceleration?
Answer:
a = 4 m/s2
Explanation:
Given: 200 N, 50 kg
To find: a
Formula: [tex]A = \frac{f}{m}[/tex]
Solution: To find a, divide the force by the weight
A = F ÷ m
= 200 ÷ 50
= 4 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

A machine used 20 J of energy to make a
bicycle start. However, 6 J of energy was
wasted as heat. What is the percentage
efficiency of the machine?
a 30%
b 75%
C 70%
d 60%
Answer:
a. 30%
Explanation:
Given the following data;
Energy as effort, Ee = 20 J
Energy as heat, Eh = 6 J
To find the percentage efficiency (P.E);
P.E = Eh/Ee * 100
Substituting into the formula, we have;
P.E = 6/20 * 100
P.E = 6 * 5
P.E = 30 %
Therefore, the percentage efficiency of the machine is 30 %.

What is the difference between sounds that have the same pitch and loudness? the standing wave the natural frequency the sound quality the resonance
Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.

Choose the correct statement below that accurately describes the shear and normal stresses in a beam. A. Shear stresses are maximum at the neutral axis and normal stresses are maximum furthest from the neutral axis. B. Normal stresses are maximum at the neutral axis and shear stresses are maximum furthest from the neutral axis. C. Shear stresses and normal stresses are maximum at the neutral axis. D. Shear stresses and normal stresses are maximum furthest from the neutral axis.
Answer:
A. Shear stresses are maximum at the neutral axis and normal stresses are maximum furthest from the neutral axis.
Explanation:
Normal stress :
Normal stress is defined as the stress or the restoring force that occurs on the plane when an external axial load is applied on it. For a beam the normal stress is maximum at the point furthest from the neutral axis and is zero at the neutral axis of the beam.
Shear stress :
Shear stress is a stress which occurs when the force acts on the surface of the member in a parallel direction. It changes the shape of the member. For a beam, the shear stress is maximum at the neutral axis.
