If carrots have 80j of energy how much energy will a rabbi get from eating the carrot

Answers

Answer:

8

Explanation:

According to the 10% law of energy transfer,

only about 10% of energy will be transferred to

the successive level from the previous trophic

level. Therefore according to this law carrot will

have the highest energy level as it is present at

the lowest trophic level.

Then it will transfer 10% of its consumed energy

to the rabbit and then snakes will get 10%

energy of rabbit after consuming it. Therefore if

the energy amount is given it can be calculated

by dividing it by 10 for upper trophic level.

So if a rabbit receives 80 calories of energy

from eating carrots it will pass only 8

(80/10=8) calory of energy on to a snake.

Therefore the correct answer is 8 calories

This type of soil is found in warm, humid climates. question 5 options: pedocal laterite pedalfer humus

Answers

Answer:

Laterite would be your answer.

Explanation:

I hope this helps!

Laterite is the type of soil is found in warm, humid climates.

What is laterite soil?

Laterite is rich in iron and aluminum soil and rock type that is thought to have originated in hot, humid tropical climates. Nearly all laterites are of rusty-red hue, because of significant iron oxide concentration.

They form as a result of intense and extended erosion of the underneath rock material, which occurs most often when there are high temperatures and significant rainfall, with alternate wet and dry intervals.

Tropical weather is a long-term chemical weathering process that results in a wide range of soil thickness. Laterite is the type of soil is found in warm, humid climates.

Hence laterite is the correct option.

What Daryl said is correct and the relationship among them is a causation than a correlation, because we know that high pitched sound wave has more frequency than that of low pitched sound wave. and we also know that if the medium is same then velocity of wave is same* so if there is high pitched sound wave, it has shorter wavelength and if there's low pitched sound wave it has longer wavelength. since there's an inverse relationship between wavelength and frequency.

What is your understanding of Electricity? Describe how electricity works, circuits, how does it move, what is moving? Where does electricity come from?

Answers

Answer:

How does Electricity work?

Electricity is a secondary energy source created at an atomic level thanks to the attraction of protons and electrons. It's generated when we move electrons around. When we move that energy down conductive wires, the electricity travels into our homes and businesses.

How does Electricity move?

Electrical energy travels as electromagnetic waves at the speed of light, which is 3*108 meters per second. The speed of electricity is quite fast even though the electrons move quite slowly. The electric field produces the force that causes these electrons to drift slowly.

Where does Electricity come from?

According to the U.S. Energy Information Administration, most of the nation's electricity was generated by natural gas, coal, and nuclear energy in 2019. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power.

velocity of the wave?
till

Answers

The sound wave travels faster at higher temperatures and slower at lower temperatures.

What will happen to the velocity of the wave if the temperature decreases?

At a lower temperature, particles of the medium are moving more slowly as compared to higher temperature. Due to lower temperature, longer time is required to transfer the energy of the sound waves.

So we can conclude that sound travels faster at higher temperatures and slower at lower temperatures.

How many electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form? 1 3 4 8

Answers

Answer:

8

Explanation:

It is because the outermost energy level carries a maximum of 8 electrons

8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form

What is a covalent bond?

The interatomic bond is formed when two atoms share an electron pair. The electrical attraction of their nuclei for the identical electrons causes the binding.

When the total energy of the bound atoms is lower than that of widely spaced atoms, a covalent bond is formed.

When an atom's outermost electron shell is full, it is the most stable and least reactive. The octet rule states that most key biological elements require eight electrons in their outermost shell to be stable.

Hence 8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form

A solid cylindrical disk has a radius of 0.15 m. It is mounted to an axle that is perpendicular to the circular end of the disk at its center. When a 50-N force is applied tangentially to the disk, perpendicular to the radius, the disk acquires an angular acceleration of 110 rad/s2. What is the mass of the disk?

Answers

Answer:

Torque = I α = 1/2 M R^2 α       where α is the angular acceleration

Torque = F R      where F is applied to a distance R from center

F R = 1/2 M R^2 α

M = 2 F / (R α) = 2 * 50 / (.15 * 110) = 6.06 kg
