The scientific name is: Enteroctopus dofleini
The diet of the octopus is: Young giant Pacific octopus feeds on dead animals and is characterized as a “neustonic feeder.” Adult preys on crustaceans, such as shrimp, crabs, scallops, clams, as well as other mollusks, flatfishes, redfish and smaller octopods.
The range is: Giant Pacific octopus occurs along the Pacific coast from Southern California north to Alaska and across to Japan. It is found in habitats that range from shallow tidal pools to ocean depths of about 4,920 feet (1500 m). It is most abundant in shallow waters to 16 feet (5 m) deep.
The charecteristics are: bulbous heads, large eyes, and eight very useful arms.
5 facts are:
1. Giant Pacific octopuses can grow to 29.5 feet (9 m) wide from the tip of one arm to the tip of another and 44 pounds (20 kg).
2. Giant Pacific octopuses can change color in one-tenth of a second.
3. Giant Pacific octopuses can be found more than 330 feet (100 m) underwater.
4. Female giant Pacific octopuses never leave their eggs during the brooding process and die shortly after from self-cannibalization.1
5. Female giant Pacific octopuses lay 18,000 to 74,000 eggs that are the size of a grain of white rice.
Human impact: Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving.
Reproduction: Giant Pacific Octopus Reproduction. After about two years, the female will seek out a male for her one time to reproduce and lay eggs. Once she finds a male, he will deposit a sperm packet into the female's mantle. The female will then store the sperm packet until she is ready to fertilize eggs.
Migration: The medium to large pacific giant is believed to go through a migratory stage in which it migrates from shallow to deep water and back again, the migratory cycle runs as follows: shallow water October-November/deep water February-March/shallow water April-May/deep water August-September.

4. Giant Pacific octopuses have huge, bulbous heads and are generally reddish-brown in color. Like the other members of the octopus family, though, they use special pigment cells in their skin to change colors and textures, and can blend in with even the most intricately patterned corals, plants, and rocks.
5. The giant Pacific octopus, also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus Enteroctopus. Its spatial distribution includes the coastal North Pacific, along California, Oregon, Washington, British Columbia, Alaska, Russia, Japan, and Korean Peninsula.
6. Humans are some of the greatest predators of the Pacific octopus. They are fished to be used as fishing bait for other creatures and to be sold as seafood. While they have the ability to inflict harm on humans if they wanted to, no attacks thus far have been fatal or even harmful.
7. After about two years, the female will seek out a male for her one time to reproduce and lay eggs. Once she finds a male, he will deposit a sperm packet into the female's mantle. The female will then store the sperm packet until she is ready to fertilize eggs.
8. Although the population of giant Pacific octopus is not considered endangered, it is important to prioritize the health of intertidal ecosystems and minimize threats such as pollution, habitat degradation from human development, and overharvesting of marine species that the octopus needs to prey upon.
9. The medium to large pacific giant is believed to go through a migratory stage in which it migrates from shallow to deep water and back again, the migratory cycle runs as follows: shallow water October-November/deep water February-March/shallow water April-May/deep water August-September.

what is the speed of a wave has a wavelength of 0.5 m/s and a frequency of 2 hz?
Answers
Answer: The equation that relates wavelength and frequency for electromagnetic waves is: λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.
10/0.5=20 meter.
Explanation:
The speed of a wave has a wavelength of 0.5 m/s and a frequency of 2 hz is 0.25 m.
What is wave ?Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.
There are two types of the wave longitudinal wave and transverse wave.
Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave.
Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a Transverse wave.
The relation between velocity, frequency and wavelength is,
c = λν
Where λ is wavelength, ν is frequency and c is velocity.
Given,
c = 0.5 m/s
ν = 2 hz
λ = ?
Putting all the values in the equation,

how would the heating curve for glass be different from the heating curve for water
Answers
Answer:
The heating curve for glass would be different from the heating curve for water because water has a strange behavior while glass also has a strange behavior but is different because it lacks the repeating crystalline structure of solids like ice, or water. Glass becomes soft and impressionable as temperature increases.
Since glass lacks the repetitive crystalline structure present in solids like ice or water, its strange behavior differs from that of glass when heated. This is because glass has a unique, strange behavior than water. As temperature rises, glass becomes brittle and impressionable.
What is Heat?A difference in temperature causes energy to flow from one body to another, recognized as heat. Energy is transferred, or heat flows, when two substances of different temperatures are brought together. The hotter body goes to the cold.
Typically, though not always, this energy transfer causes the temperature of the region of lower temperature to rise and the temperature of the warmer object to fall. It is possible for a substance to absorb heat without increasing its temperature by migrating from one physical state (or phase) to another, such as melting, sublimation, boiling, or shifting from one solid form to the other.

Answers
The distance between the two objects is 1.5 cm.
To calculate the distance between the two objects, we use the formula obtained from Columb's law
What is Columb's law?Columb's law states that the force of attraction or repulsion between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Formula:
F = kqQ/r²............... Equation 1Where:
F = Force between the two objectsr = Distance between the objectsQ and q = charges on both objects respectively.k = Columb's constantMake r the subject of the equation
r = √(kqQ/F).............. Equation 2From the question,
Given:
F = 60 Nq = 1.2×10⁻⁶ CQ = 1.2×10⁻⁶ Ck = 8.99×10⁹Substitute these values into equation 2
r = √[(1.2×10⁻⁶×1.2×10⁻⁶×8.99×10⁹)/60]r = √[(12.9456×10⁻³)/60]r = √(2.16×10⁻⁴)r = 1.47×10⁻² mr = 1.47 cmr ≈ 1.5 cm.Hence, The distance between the two objects is 1.5 cm.

Define propagation of sound
Answers
Considering the definition of speed and propagation of sound, sound is a sequence of waves of pressure which propagates through compressible media and depends on the characteristics of the medium in which the propagation occurs.
Definition of speed and propagation of soundSound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
That is, sound is a longitudinal wave, mechanical (does not travel in a vacuum) and propagates in all directions, so that the wave front is spherical.
Propagation of sound involves energy transport without matter transport, in the form of mechanical waves.
The speed of propagation of a sound wave depends on the characteristics of the medium in which the propagation occurs and not on the characteristics of the wave or the force that generates it. The speed of propagation of sound waves is also known as the speed of sound.
