What happens during the carbon fixation stage of the calvin cycle (light-indepedent reactions)?.
One of the Calvin cycle's three phases is carbon fixation. The inorganic carbon atom is incorporated into the organic molecule during this process.
Describe carbon fixation.Carbon fixation is the process by which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules. Chemical energy is stored in these molecules. The sustainability of life depends on this process.
The Calvin cycle of photosynthesis has a step called carbon fixation. At this point, the enzyme rubisco was used to link RuBP to the inorganic carbon atom, which had been fixed into the organic molecule.
Three carbons are fixed in this process for each turn of the light independent cycle. In this process, 3 carbons fix for each turn during the light independent cycle. Every three-carbon fixation leads to 6 3-PGA in end.

Assuming a constant angular acceleration, the linear acceleration of a point on the edge of the wheel 2.0 s after the wheel has started accelerating is equal to the angular acceleration multiplied by the radius of the wheel.
What is acceleration?
Acceleration was the last mathematical concept covered in Lesson 1. Acceleration is a frequently misunderstood concept that means something very different from what sports announcers or other people usually mean when they use it. Acceleration is described as follows: The rate that an object keeps changing its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is accelerating. Sometimes when a person is moving quickly, sports announcers will say that the person is accelerating. But speed has nothing to with acceleration. Even when moving very quickly, a person may not be accelerating. Changing the speed at which an object is moving is what acceleration is all about.
Assuming a constant angular acceleration, the linear acceleration of a point on the edge of the wheel 2.0 s after the wheel has started accelerating is equal to the angular acceleration multiplied by the radius of the wheel.

serenity challenges carlos to come up with a way to use the double-slit experiment to determine the wavelength of monochromatic light. which response is correct?
The double slit experiment can be explained using the condition of the interference with which we can find the wavelength of the monochromatic light.
When waves gather, they can interfere constructively or destructively. To build a stable and well-defined interference pattern, two conditions must be met:
The wave source must be coherent. That is, they emit identical waves with a constant phase difference.
Waves should be monochromatic - they should have a single wavelength. Suppose we have two sources emitting the same wave in phase. Whether constructive or destructive interference occurs at points close to the source depends on the path length difference δ. This is the distance from the point to one source minus the distance from the point to the other source.

This is the distance between consecutive corresponding points of the same phase in the wave. A crest, trough, or zero-crossing of two adjacent waves, characteristic of both traveling and standing waves, and other spatial wave patterns. The reciprocal of wavelength is called spatial frequency. Wavelength is usually represented by the Greek letter lambda (λ). The term wavelength is also sometimes applied to the sinusoidal envelope of modulated waves and waves formed by interference of modulated waves or multiple sinusoids.

how do sun and moon cause the ocean currents
The sun and moon cause ocean currents in several ways. First, the sun's heat causes the ocean water to expand and become less dense, which creates a rise in sea level. This rise in sea level creates a current that flows away from the equator and towards the poles.
Second, the moon's gravitational pull causes the oceans to bulge, creating tidal currents. These tidal currents can be very strong, and they cause the water to flow in circular patterns around the coasts.
Third, the moon's gravitational pull also causes the earth to rotate on its axis. This rotation creates a current called the Coriolis effect, which causes the ocean water to move in a circular pattern around the earth. This current helps to distribute heat and nutrients throughout the oceans.
Overall, the sun and moon cause ocean currents through their effects on sea level, tidal forces, and the earth's rotation.
Answer:
The sun warms up parts of the oceans. Warm waters rise just like warm air rises. So, as the warmer ocean waters begin to rise in a particular area, the cooler ocean waters from a different area will move in to replace the warmer ocean waters, and this creates our ocean currents.

Equilibrium, in physics, the state of a system when neither the state of motion nor the state of internal energy tends to change over time. A simple mechanical body is in equilibrium when it experiences neither linear nor angular acceleration. This state will continue indefinitely unless disturbed by an external force. Equilibrium occurs for a single particle when the vector sum of all forces acting on the particle is zero. A rigid body (which by definition differs from a particle by its properties of extension) is in equilibrium when, in addition to the states listed above for particles, the vector sum of all torques acting on the body is equal to zero, Its state of rotational motion remains constant. An equilibrium is said to be stable when a small externally induced displacement from that state produces a force opposing the displacement tending to return the body or particle to the equilibrium state. Examples include weights suspended from springs or bricks placed on a flat surface. Equilibrium is unstable when small deviations produce forces that tend to increase the displacement.

what is the lift (in newtons) due to bernoulli's principle on a wing of area 89 m2 if the air passes over the top and bottom surfaces at speeds of 260 m/s and 180 m/s , respectively?
Bernoulli's principle predicts that a wing with an area of 89 m² will experience a lift of 2020656 N when air moves over its top and bottom surface with velocities aircraft 260 m/s and 180 m/s, respectively.
Why is the Bernoulli principle crucial?Engineers can use Bernoulli's Principle to safely engineer the fluid flow within and around airplanes, engines, and healthcare delivery devices by making sense of a fluid dynamics phenomenon. Bernoulli's principle, a fundamental idea in fluid dynamics, connects a fluid's pressure to its speed.
Briefing:According to the Bernoulli's principle, the determined based expresses force:
[tex]P_{1} + \frac{1}{2}p(v_{1})^{2} = P_{2} + \frac{1}{2}p(v_{2})^{2}[/tex]
[tex]P_{1} - P_{2}[/tex] = (0.5) (1.29) (260)² - (0.5) (1.29) (180)²
P₁ - P₂ = 22704
F = PA = (22704) (89)
F = 2020656 N
A wingspan with either an area measuring 89 m² has a load of 2020656 N as a result.

if the rotational speed of a cd changes from 475 rpm to 200 rpm as it plays 30 minutes of music, what is the cd's average rotational acceleration?
The duration of a CD is 59.8 minutes. The CD is rotating angularly at 460 revolutions per minute when the music begins (rpm).
The temporal rate at which angular velocity changes is known as angular acceleration. The standard unit of measurement is radians per second per second. Therefore, = d d t. Rotational acceleration is another name for angular acceleration. After the music has finished, the CD is spinning at 202 rpm. The beginning angular velocity was 460rpm/60*2*Pi, which equals 48.17rad/s. The end angular velocity was 202rpm/60*2*Pi, which equals 21.15rad/s. The time in s was 59.8min*60, which equals 3588s. The angular acceleration was (21.15 - 48.17)/3588.

draw the process and control scheme for this system if a constraint controller is used, such that when the smaller of two parallel control valves reached 100%, then the controller output is routed
Technique controllers keep the output of manner variables together with temperature, pressure, glide, or stage within a pre-set variety.
Manner controllers maintain the output of machine variables together with temperature, strain, glide, or degree inner a pre-set variety. They use feedback from sensors to discover any deviation from a setpoint and automatically alter output until parameters are again inside variety.
The challenge of a constraint control scheme is to push a target variable as a ways as viable in the preferred course. With distinctive phrases, The purpose variable shall obtain is relying on the goal most or minimal rate without violating some other boundaries.
Constraints are used to restrict the form of data which can go right into a table. This guarantees the accuracy and reliability of the data inside the desk. If there can be any violation among the constraint and the facts motion, the movement is aborted. Constraints may be column degree or table stage.
