In  ecosystem, particles are carried as  bed load by rubbing particles together.Path of stream can be varied depending on amount of humus present in  soil and is measured in cubic meters per second and carrying capacity depends on  type of material through which stream flows.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explanation:

its common sense

Answer:

Newton's Third Law of Motion states that to every action there is an equal and opposite reaction. When the earth pushes on you to send you into the air after jumping, you also push on the earth with the same force. But forces are different from accelerations. A force F is a push or pull on an object

Copper is a chemical element, a reddish, and extremely ductile metal of Group 11 of the periodic table that is an unusually good conductor of electricity and heat. It is found in the free metallic state in nature.

Explanation:

Answer:

A

Explanation:

The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.

Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.

Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.

For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

Magnesium Ion

Explanation:

This is a Magnesium ion. There are 12 protons from the magnesium atom. There are 10 electrons because 12-2=10. There are 12 neutrons because 24-12=12

Answer:

The electronegativity from order of least to highest is:

Ne, Ca, Fe, F

Explanation:

Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).

According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.

Hence, based on Pauling scale, the order of electronegativity from least to highest is:

Ne > Ca > Fe > F

Answer:

A). Arrow A shows the direction heat flowed because the temp of his hand increased as the heat was absorbed by his hand.

Explanation:

As per the given description, Eric can conclude that when 'heat is either prepended or separated from an object after the completion of his test' as arrow A displays the direction in which the heat has flown because his hands' temperature increased after the heat was absorbed by his hand. It implies that heat is prepended when the temperature of his hand increases and vice versa when the heat is removed. Thus, option A is the correct answer.

letter A is right.

1) Sour taste - Put some soda on your tongue

2) Corrode metals - Put a little soda on a clean metal surface

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

Explanation:

The amount of energy which  is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C is 49,545 J.

Amount of energy absorbed by any material will be calculated by using the below equation:

Q = mcΔT, where

m = mass of aluminum = 0.2 kg

c = specific heat of aluminum = 897 J/kg.K

ΔT = change in temperature = 18 - 15 = 3°C = 276.15 K

On putting these value on the above equation, we get

Q = (0.2)(897)(276.17) = 49,544.89 = 49,545 J

Hence required amount of energy is 49,545 J.
