One step of copper mining requires blasting ore to be able to blasted and extracted from mine.
This process causes harm to the Geosphere (Lithosphere)In this step, they blast the mines inside the earth. Which causes destruction and harm to the geosphere. We know that, land comes under Geosphere also known as Lithosphere.Mercury is used to recover minute pieces of gold that is mixed in soil and sediment. Sometimes Mercury can be lost in this process resulting in widespread contamination of local rivers and lakes.
This causes harm to the Hydrosphere.The portion of earth covered with water is known as hydrosphere.Since, The Mercury is getting mixed with the water. It is polluting the water that is the hydrosphere.Hundreds of tons of rock are unearthed, moved and crushed in mining operation significantly increasing the amount of dust and particulates in the air.
This causes harm to the Atmosphere.The particles of dust get increased in air and eventually gets mixed and spread everywhere.The air is getting polluted which means the atmosphere is getting harmed.Strip mining (also known as mountaintop removal) involves scraping away earth and rocks to get to coal buried near the surface. This often results in the destruction of ecosystems.
This causes harm to the Biosphere.The biosphere consists of plants and animals. And these plants and animals collectively form a habitat called ecosystem.When a ecosystem is destroyed, the biosphere is harmed.one step of copper mining requires blasting ore to be able to blasted and extracted from the mine

why freezer is made in the upper part of refrigrator
✒ Answerthe cold air produced from it is denser than the warmer air in the bottom
ExplainationFreezer is normally provided at the top of the refrigerator, because density of the cold air is high compared to the hot air. In a refrigerator the air contacts with the cooling coil and gets cooling.Because of the high density the cold air gets down and the warm air/hot air moves upward and gets cooling from the cooling coil/evaporator coil. This process is repeated. If the Freezer is provided at the bottom place of the refrigerator, the cold air can't to move full area of the refrigerator. So the freezer is normally provided at the top at the refrigerator

wht is error of parallax?
Answers
Answer: A parallax error is an apparent shift in an object's position as it is viewed from different angles. For example, the error is most easily noticed by looking at a nearby object with one eye closed, then looking at it through the other eye.
Explanation: Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances.
If two objects of the different masses are pushed with the same force; which will travel faster?
Answers
Using the formula force = mass*acceleration, you can plug in different variables to test out which mass has a greater acceleration:
F=ma
Small mass: m1=1 kg
Large mass: m2=2 kg
Force: F=3 N
Acceleration for small mass:
3=1a
a=3 m/s^2
Acceleration for large mass :
3=2a
a=1.5 3m/s^2
Since the large mass has a lesser acceleration, the small mass (with a greater acceleration) would travel faster.

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.
2. Young giant Pacific octopus feeds on dead animals and is characterized as a “neustonic feeder.”

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.

Answers
Here is your Answer:-
In optics, an image is defined as the collection of focus points of light rays coming from an object. A real image is the collection of focus points made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. In other words, a virtual image is found by tracing real rays that emerge from an optical device (lens, mirror, or some combination) backward to perceived or apparent origins of ray divergences. In diagrams of optical systems, virtual rays are conventionally represented by dotted lines.
Because the rays never really converge, a virtual image cannot be projected onto a screen. In contrast, a real image can be projected on the screen as it is formed by rays that converge on a real location.

The figures below show forces of different magnitudes that are exerted on the bar at different locations. In which case does the bar’s angular speed about the axis increase at the fastest rate?.
Answers
The case where the angular speed of the bar will increase at a fast rate is at smaller radius compared to the initial radius from the center of rotation.
Conservation of angular momentumThe principle of conservation of angular momentum states that the total angular momentum of a closed system is always conserved.
[tex]I_i \omega _i = I_f \omega _f[/tex]
where;
Ii is initial moment of inertia of the solid sphereIf is the final moment of inertia of the solid sphereωi is the initial angular speed ωf is the final angular speed[tex]\omega _f = \frac{I_i \omega _i }{I_f} \\\\\omega_f = \frac{(1/2MR_i^2)\omega _i}{1/2 MR_f^2}\\\\\omega _f = \frac{R_i^2 \omega _i}{R_f^2}[/tex]
where;
M is mass of the barR is radiusThe angular speed of the bar depends of the moment of inertia of the bar which in turn depends on axis of rotation.
Thus, the case where the angular speed of the bar will increase at a fast rate is at smaller radius compared to the initial radius from the center of rotation.
