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.

the magnetic flux density's induced emf across the coil is equal to 5e^-2t.

The magnetic flux across a surface in physics, specifically electromagnetism, is the surface integral of the normal component of the magnetic field B over that surface. The standard notation is B or. The weber is the SI unit for magnetic flux, and the maxwell is the CGS unit.

According to Faraday's law, induced EMF is equal to the rate at which magnetic flux changes. BA = Magnetic flux = Area x Magnetic field strength. As a result, induced EMF is calculated as follows: (change in Magnetic Flux Density x Area)/change in Time.

If the floor were not frictionless, the sphere's angular speed would change and increase until the sliding between the sphere and the floor came to an end. As a result, correct option is C.

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.

A solid sphere is placed on a frictionless floor in a very long corridor and is given a quick push so that it begins to slide, without rotating, along the corridor. How would the angular speed of the sphere be changing if the floor were not frictionless?

A.) It would remain zero because the net torque is still zero.

B.) It would remain zero because the angular momentum is conserved.

C.) It would be increasing until the slipping between the sphere and the floor stops.

D.) It would be increasing until the linear and the angular speeds become equal.

If I wanted to search for faint rings around a giant planet, the best option to make my observations is e)after the spacecraft passed the planet. So, correct option is e.

Planets having faint rings are:

Saturn -it is considered as the most attractive planet with rings in our Solar System, since they are made up of a very large ring system, which even has different areas and interior systems. Composition of rings are mostly of dust and ice particles.

Uranus-This planet too has a ring system. It is a less colorful system than that of Saturn, but more colorful than that of Jupiter. It is made up of a total of 13 well-defined and structured rings.

Neptune-The last planets in the Solar System  (since Pluto is not considered as the planet because of its extinction) that has a ring system is Neptune. This ring system looks similar to  Jupiter’s, very faint and difficult to identify without taking  help of very special equipment and space telescopes.

Ionic bond energies typically range from 170 to 1500 kJ/mol (cited estimates vary). Purely ionic compounds have spherical ions in their crystal lattices; however, if the positive ion is tiny and/or highly charged.

It will deform the negative ion's electron cloud, an effect encapsulated in Fajans' laws. An ionic bond is a stable bond created by the full transfer of the valence electron. Positive ions, known as cations, and negative ions, known as anions, are created as a result of this type of connection.

Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created.

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.

The sound level drops by 7.6 dB when we move 2.4 times as far away from the bird.

The decibel ratio of the measured sound intensity to the reference sound intensity is known as the sound intensity level (SIL), also known as the acoustic intensity level.

Let the initial distance be r₁ and the moved away distance be r₂. Then, r₂=2.4r₁.

Let the initial intensity be I₁ and the moved away intensity be I₂.

Then, the relationship between sound intensity and distance is,

[tex]\frac{I_2}{I_1}=\frac{{r_1}^{2}}{{r_2}^{2}}[/tex].

Let β₁ and β₂ be the two sound intensity levels. The difference in sound intensity is given by,

[tex]\begin{aligned}\beta_2-\beta_1&=\mathrm{10\;dB}\left(\log\frac{I_2}{I}-\log\frac{I_1}{I}\right)\\&=\mathrm{10\;dB}((\log I_2-\log I)-(\log I_1-\log I))\\&=\mathrm{10\;dB}\log \frac{I_2}{I_1}\end{alinged}[/tex]

The average intensity of solar radiation incident on the upper atmosphere of the earth is = 1390 w/m² (ii)

The intensity of radiation emitted from a source in all directions at a distance r can be found by dividing the total energy emitted per second or power P by the surface area of a sphere of radius r. So, the intensity of radiation at a given point. Using the values of (i), (ii), we get -

This failure or this maximum force that the beam can withstand can be found out by bending moment diagram. According to this diagram, the failure occurs at the mid-point of the beam. If the force is uniform or acting on the mid-point of the beam.

If the force is anywhere except at the mid-point then the failure occurs at the point of application of the force. The maximum force is present at the point of application and from the nearest end, the force linearly increases.

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.
