Explanation:

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

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

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.

Answer:

A

Explanation:

It depends on the scale of the volcanic eruption. A smaller eruption may only affect the nearby area, but a large one can affect the whole world. For example, the Krakatoa eruption of 1883 created an ash cloud which lowered global temperatures and affected the climate for a year afterwards.

An explosive eruption by a single volcano can affect only the lifeforms living on the volcano. The correct option is B.

A volcano is an opening in the Earth's surface through which molten rock, ash, and gas can escape. Volcanoes are formed by the movement of tectonic plates, which create weak spots or vents in the Earth's crust where magma can rise to the surface.

Volcanoes can form in different ways, but most are formed at plate boundaries, where one tectonic plate is moving under another (subduction zone), or where two plates are moving away from each other (divergent boundary). When magma rises to the surface, it can form a volcanic cone or mountain over time.

There are three main types of volcanoes, based on their shape and the type of eruptions they produce:

(i)Shield volcanoes - broad, gentle slopes formed by lava flows that spread out over a wide area.

(ii)Stratovolcanoes (also called composite volcanoes) - tall, steep-sided cones formed by alternating layers of lava, ash, and other volcanic debris.

(iii)Calderas - large, basin-shaped depressions that form when a volcano collapses or erupts so forcefully that it empties its magma chamber.

Volcanoes can be active, dormant, or extinct. Active volcanoes are those that have erupted recently or are expected to erupt soon, while dormant volcanoes have not erupted in a long time but could still erupt in the future. Extinct volcanoes are those that have not erupted in thousands of years and are unlikely to erupt again.

Here in the question,

An explosive eruption by a single volcano can have a significant impact on the surrounding environment and local communities, but its effects are generally limited to the immediate vicinity of the volcano. The eruption may release ash, gases, and lava flows that can cause damage to nearby ecosystems and affect the health of humans and animals living in the area. However, the effects are unlikely to extend beyond the local region, let alone affect lifeforms throughout the world.

Therefore,  B. only the lifeforms living on the volcano, is the correct option.

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2

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

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

The lens parameter that enables us to brighten an image is called" Refractive Index"

Refractive index of a material is a dimensionless number that describes how fast light travels through the material. Refractive Index is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.

Therefore, refractive index is the lens parameter that enables us to brighten an image.

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.
