Can someone help me answer this ASAP!! thank you!

Answer:

Sandy soil

Explanation:

Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.

Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.

Permeability is very important for determining the quality of soils.

There are 5 stages of breast cancer: stage 0 (zero), which is non-invasive ductal carcinoma in situ (DCIS), and stages I through IV (1 through 4), which are used for invasive breast cancer. The stage provides a common way of describing the cancer, so doctors can work together to plan the best treatments.

Answer:

Pressure is an important physical quantity—it plays an essential role in topics ranging from thermodynamics to solid and fluid mechanics. As a scalar physical quantity (having magnitude but no direction), pressure is defined as the force per unit area applied perpendicular to the surface to which it is applied. Pressure can be expressed in a number of units depending on the context of use.

Answer:

H⁺(aq) + OH⁻(aq) = H₂O(l)

Explanation:

To find the net ionic equation start by finding the balanced equation.

2HClO₄(aq) + Ba(OH)₂(aq) ⇒ 2H₂O(l) + Ba(ClO₄)₂(aq)

Then put it into the ionic equation.

2H⁺(aq) + 2ClO₄(aq) + Ba²⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l) + Ba²⁺(aq) + 2ClO₄(aq)

Remove all the ions that do not change.

2H⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l)

And reduce to the lowest common coefficient.

H⁺(aq) + OH⁻(aq) = H₂O(l)

Answer:

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

because potential energy is created with the position of a body when you pick up something the thing will have stored energy which is transferred from you so the stored energy is potential energy created by the position of a body that when you see over your head you scared of that thing not to bit you because it has stored energy if you see the thing already failed on the ground you wouldn't scared of that because the enery is already gone

The lightning storm is just what you'd expect it to be, and the comb is collecting particles of what looks like paper?

Anyway, the rock and the magnet are forcefully pulling the metal objects towards it with electromagnetism.

Answer:

A

Explanation:

An atom that is a different isotope of a given element would contain 6 protons, 7 neutrons, and 6 electrons. Therefore, option (A) is correct.

Isotopes are atoms of an element that contain the same atomic number as the original element but a different atomic mass. Isotopes of an element possess the same number of electrons and the number of protons but different numbers of neutrons in their respective nucleus.

For example, the isotopes of carbon are carbon-14, carbon-13, and carbon-12. Carbon-14 has a total of 8 neutrons, carbon-13 have a total of 7 neutrons, and carbon-12 has a total of 6 neutrons. So all the isotopes of carbon have different numbers of neutrons.

Given element has 6 protons, 6 neutrons, and 6 electrons. So the isotope of this element will have  6 protons, and 6 electrons but not 6 neutrons. Therefore, the element with 6 protons, 7 neutrons, and 6 electrons is the isotope of the given element.

Sodium-22 remain : 1.13 g

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually, radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

half-life = t 1/2=2.6 years

T=15.6 years

No=72.5 g

[tex]\tt Nt=72.5.\dfrac{1}{2}^{15.6/2.6}\\\\Nt=72.5.\dfrac{1}{2}^6\\\\Nt=1.13~g[/tex]

Answer:

The answer is A. Construction. The production of raw materials for construction in factories is harmful for the environment due to CO2 emissions. The chemicals used in construction and the diesel used by construction vehicles are also harmful to the environment.

Explanation:

In an ecosystem , human activity which constitutes to air pollution is construction.

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 ecosystem 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.There are different types of ecosystems.

Explanation:

Answer:

B.Hypothese

Explanation:

i don't know but that's first came in my mind

Answer:

a hypothesis

Explanation:

A hypothesis is a statement that is supposed or assumed before conducting any experiment. It is the assumption that is made on the basis of certain knowledge and controlled evidence in the initial time of the experiment. The initial assumption helps in taking the experiment or the investigation further. The truth is not ascertained in the initial phase rather the completion of the investigation is necessary to make a hypothesis turn into a theory.  

In the given situation, the statement given is a hypothesis because the use of the warm water for the growth of the plants is the assumption made with respect to the metabolism effect on the humans.

Answer:

See explanation

Explanation:

When the bromine free radical attacks 2,3-dimethylbutane, two free radicals may result. One of them is primary (formed by attack on then end -CH3 group) the other is secondary.

Recall that the order of stability of free radicals is tertiary > secondary > primary > methyl.

Hence the secondary free radical is more thermodynamically stable hence it is the major free radical formed in the first propagation step.
