The statement 'CO2 is removed from the atmosphere, and O2 is released' describes the redox reaction involved in photosynthesis. It is a redox reaction.
What is photosynthesis?
Photosynthesis refers to a series of reactions by which plants can produce simple carbohydrates by using solar radiation and oxygen (O2).
These photosynthetic reactions are well known to release carbon dioxide (CO2) into the atmosphere.
During Photosynthesis, CO2 is reduced to simple carbohydrates (e.g., glucose), while water (H2O) is oxidized to O2, thereby producing a redox reaction.

What is the work done by gravity on a 4 kg ball
a. as it goes from point B to point A?
b. As it goes from point A to C?
(horizontal distance between A and B is 8 m; between B and C is 3.2 m)
Answer:
a. Work done = 313.92 Joules
b. Work done = 439.49 Joules
Explanation:
Work done = Force x distance
Where: Force = mass x gravity
Thus,
Work done = Force x gravity x distance
The earth's acceleration to gravity = 9.81 m/[tex]s^{2}[/tex].
a. The work done as it goes from B to A can be determined as;
work done = 4 x 9.81 x 8
= 313.92 Joules
b. The distance between A and C is the total horizontal distance covered from A to C.
i.e 8 + 3.2 = 11.2 m
The work done as the ball goes from point A to C can be determined as:
work done = 4 x 9.81 x 11.2
= 439.488
work done = 439.49 Joules

In which of these can convection not occur
A. Gases
B.solids
C.liquids
D.fluids
I believe the answer would be B.solids.
Explanation:
Hope this helped!
In solids these can convection not occur and convection can occur in both liquids and gases, as they are both considered fluids. Thus, option B is correct.
However, convection cannot occur in solids, as the particles in solids are generally fixed in position and do not have the freedom to move and transfer heat through bulk motion as in convection.
A solid is one of the three fundamental states of matter, along with liquids and gases. It is characterized by having a definite shape and volume. Solids are composed of tightly packed particles, such as atoms, molecules, or ions, that are held together by strong intermolecular forces.
These particles vibrate in fixed positions but do not have the ability to move freely throughout the substance. As a result, solids maintain their shape and volume under normal conditions and exhibit relatively low compressibility compared to gases and liquids. Examples of solids include metals, rocks, wood, plastics, and ice.

1) Do waves transport energy or matter?
Tell me what the laws of thermodynamics are in a simple way
Answer:
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

A rope is used to pull a box 15.0 m across a floor. The rope is held at an angle of 46.0˚ and a force of 628 N is used along the rope. What is the work done? Your answer should be rounded to the tenths place, and include the correct units. View question
Answer:
6544.07 J
Explanation:
From the question given above, the following data were obtained:
Distance (d) = 15 m
Force (F) = 628 N
Angle (θ) = 46°
Workdone (Wd) =?
The work done can be obtained by using the following formula:
Wd = Fd × Cos θ
Wd = 628 × 15 × Cos 46
Wd = 9420 × 0.6947
Wd = 6544.07 J
Therefore, the workdone is 6544.07 J

Why can water dissolve some ionic compounds, like NH4Cl, as well as some nonionic compounds, like methanol?
Answer:
Water is polar molecule. ... The ionic compounds are dissolved as these ions attract the hydrogen( negative charge attraacts them) and oxygen (positive charge attracts them) whereas methanol is a polar molecule and forms hydrogen bond with water molecules and hence dissolves.

Explanation:
Triply charged uranium-235 and uranium-238 ions are being separated in a mass spectrometer. (The much rarer uranium-235 is used as reactor fuel.) The masses of the ions are 3.90×10−25kg3.90×10−25kg and 3.95×10−25kg,3.95×10−25kg, respectively, and they travel at 3.0×105m/s3.0×105m/s in a 0.250-T field. What is the separation between their paths when they hit a target after traversing a semicircle? (b) Discuss whether this distance between their paths seems to be big enough to be practical in the separation of uranium-235 from uranium-238.
Answer:
[tex]0.025\ \text{m}[/tex]
Yes
Explanation:
[tex]m_8[/tex] = Mass of uranium 238 ion = [tex]3.95\times 10^{-25}\ \text{kg}[/tex]
[tex]m_5[/tex] = Mass of uranium 235 ion = [tex]3.9\times 10^{-25}\ \text{kg}[/tex]
v = Velocity of ions = [tex]3\times 10^5\ \text{m/s}[/tex]
q = Charge of triply charged ions = [tex]3\times 1.6\times 10^{-19}\ \text{C}[/tex]
B = Magnetic field = 0.25 T
The force balance is
[tex]\dfrac{mv^2}{r}=qvB\\\Rightarrow r=\dfrac{mv}{qB}[/tex]
The difference between the radius of the ions are
[tex]\Delta r=(m_8-m_5)\dfrac{v}{qB}\\\Rightarrow \Delta r=\dfrac{(3.95\times 10^{-25}-3.9\times 10^{-25})\times 3\times 10^5}{3\times 1.6\times 10^{-19}\times 0.25}\\\Rightarrow \Delta r=0.0125\ \text{m}[/tex]
Separation is given by
[tex]\Delta d=2\Delta r=2\times 0.0125\\\Rightarrow \Delta d=0.025\ \text{m}[/tex]
The separation between their paths when they hit a target after traversing a semicircle is [tex]0.025\ \text{m}[/tex].
Yes, the distance between the paths is 2.5 cm is a practical separation between as it is easily measurable.

The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
Hope this helps!
Answer:
This
Explanation:
First Law: Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
Second Law: In other words, it states that the force that is applied in the crash is proportional to mass of impacting cars. This means that the bigger the force of impacting cars, the bigger the force applied, which implies a greater destruction.
Third law: Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

If the efficiency and mechanical advantage of a certain machine are given as 65 % and 3 respectively.What is the velocity ratio of the machine?
a.3.5 %
b.4.6 %
c.7.9 %
d.11.2 %
Answer:
b. 4.6 %
Explanation:
From the question,
E = M.A/V.R................ Equation 1
Where E = percentage Efficiency of the machine, M.A = machanical accurancy of the machine, V.R = Velocity ratio of the machine
Make V.R the subject of the equation
V.R = M.A/E
Given: M.A = 3, E = 65% = 0.65
Substitute this values into equation 2
V.R = 3/0.65
V.R = 4.6
Hence the right option is b. 4.6 $
