The order of diffraction, m, is represented in this equation.
denotes the incident light's wavelength.
The separation of the two slits' centers is measured in terms of d.
The angle at which the mth order would diffract is given by,.
Utilizing the visible spectrum's maximum wavelength of 700 nm, we can determine the smallest spacing necessary to observe one full order of the visible spectrum.
d = mλ / sin (θ)
In order for sin () to be the greatest and the distance d to be the smallest,
Therefore, 700 nm is the minimum separation that would allow for the capability of detecting the full first order of the visible area spectra. Using this information, we can find the maximum number of lines per centimeter, which is the reciprocal of the number of lines per cm.
n = 1/d = 1, 430,000 lines per m, or 14,300 lines per cm.

How do grasshoppers smell?.
The grasshoppers smell on the antennae.
Grasshoppers sense contact through organs located in different parts of the body such as antennae and apply on the head serti on the abdomen and receptors on the legs. The gustatory organs are located in the mouth and the olfactory organs are located in the antennae. Grasshoppers have such powerful leaping legs that people sometimes don't realize they also have wings.
While locusts use their jumping ability to gain momentum in the air most grasshoppers have fairly powerful flight abilities and make good use of their wings to evade predators. Locusts are non-venomous and pose no danger to humans. But they have strong jaws! It may be temporarily painful. Most grasshoppers mean rubbing their hind legs against their forewings. Special vertebrae on the inside of the hind legs act like a kind of percussion instrument when in contact with the thickened edges of the wings.

Bh³/3 is the moment of inertia of a rectangular block of mass m.
Moment of inertia is a term used to describe a body's resistance to having the direction of its rotation along an axis changed by the application of a torque (turning force).
Axis options include internal, external, fixed, and moving. The moment of inertia (I), which is always represented in relation to that axis, is obtained by adding the results of multiplying each particle's mass by the square of its distance from the axis in the specific body. When determining the angular momentum of a rigid body, moment of inertia is equal to mass in linear momentum.

What are the 7 stages of the rock cycle?.
The 7 stages of the rock cycle are weathering, erosion and transport, deposition of sediment, burial and compaction, melting, uplift and deformation and metamorphism.
Weathering is a process of breaking down of rocks into smaller particles. Factors like temperature extremities, water and biological involvement of nature play an important role.
Erosion is a process of breaking down of rocks into sand-like particles. In the previous stage, water was only present as a factor for reactions to take place, while in erosion it acts as a transporting agent too.
Sediment is the constant deposition of small particles of sand, pebbles, that are broken down from rocks.
Burial and compaction happens when the sand particles are sedimented, they create layers which are soon covered by another layer of new sediments and the process goes on.
As soon as the rocks reach the bottom of the earth, the temperature rises and so does the pressure.
The process of forming a crust of earth upwards due to natural forces causing movement in the tectonic plates is called uplifting.

What is friction and what is the role it plays here?When something moves over or rolls over another solid object, there is friction. Even though friction force can be advantageous, such as the traction needed to move without slipping, they also present a sizable amount of resistance to motion.
Friction between alloys appears to be primarily caused by the attraction forces, also called as stickiness, between the contact zones of the surfaces, which are always microscopically unequal. As the defects of the rough surface rub up against the softer surface, the "welded" seams are torn apart and friction is produced.

temperature and light intensity are two factors that affect the rate of photosynthesis. which of these factors would you expect to have the greatest effect on the rate at which the calvin cycle proceeds, and why?
At Calvin cycle, temperature has a greater effect compared to light intensity.
Temperature regulates the rate of photosynthesis. The rate of photosynthesis increases with increased temperature. This is due to the fact that photosynthesis is a chemical reaction that is increased by temperature. At higher temperatures, the enzymes simply stop working and become denatured.
Furthermore, the temperature has an impact on the cycle. Because it relies on enzymes, temperatures that are either too high or too low will have an impact.
Meanwhile, a plant cannot photosynthesise efficiently if there is insufficient light even if there is enough of water and carbon dioxide and the temperature is appropriate. Increasing the intensity of the light raises the pace of photosynthesis until some other factor—a limiting factor—runs out.

Rewriting to find [tex]P_2[/tex]:
[tex]P_2=\frac{P_1V_1}{V_2}[/tex]
[tex]P_1=4.39atm\\V_1=5.26L\\V_2=3.78\\P_2=\frac{(4.39atm)(3.26L)}{3.78L}\\P_2=3.7861atm[/tex]
This answer follows Boyle's statement that pressure is inversely proportional to volume (V∝[tex]\frac{1}{P}[/tex]). As the volume decreases, the pressure must proportionately increase.
What are the effects of quotas?.
Import quota effects on the importing country's producers.
In the field of economics quota signifies the time-bound restrictions governments impose on trade. Generally this is done to preserve and motivate domestic business and balance trade. Governments implies quotas by placing barriers on the value or number of exported or imported goods.
Quotas limits market reach to imported products, which significantly results usually into an increase in the domestic price paid by consumers. This leads to a decrease in consumer surplus and lower real incomes.Quotas impose by employers may become less attractive to the job applicants who are male. Quotas may also lead to low engagement and negative job attitudes among male employees. Furthermore, this perception of unfairness may also cause men to be less supportive of diversity policies than they were at their initial stage to implementing quotas. All the benefits of quotas goes to the both producers and to the lucky importers who manage to get the scarce and valuable import permits.Hence, import quota effects on the importing country's producers.

what is the maximum wavelength of light (in nanometers) that would produce an output from a photovoltaic device manufactured from a semiconductor with an energy gap of 1.02 ev?
The maximum wavelength of light that would produce an output from a photovoltaic device manufactured from a semiconductor with an energy gap of 1.02 eV is 121 nanometer.
Given,
Energy gap = 1.02 eV
Wavelength = ?
We know that,
Speed of light, c, is given as 3 * 10⁸
Planck's constant, h, = 6.626 * 10⁻³⁴
Charge on photons = 1.602 * 10⁻¹⁹
To calculate the maximum wavelength of light we will use a formula of Einstein's equation
Mathematically, Einstein's equation for photon energy is given by this formula:
E = hf = hc/λ
Where:
E is the energy.
h is Plank's constant.
λ is the wavelength.
c is the speed of light.
To find wavelength using the above formula
λ = hc/E
Now, substituting the values, we get
λ = (6.626 * 10⁻³⁴)(3 * 10⁸) / (1.02)(1.602 * 10⁻¹⁹)
λ = 1.21 * 10⁻⁷ m
In 1 nanometer we have 10⁻⁹ m
λ = 121 nm
Therefore, the maximum wavelength of light that would produce an output from a photovoltaic device manufactured from a semiconductor with an energy gap of 1.02 eV is 121 nm.
