Answer:

Area of rectangular poster = \frac{3}{16} yard²

Explanation:

P.S - The exact question is -

Given - A rectangular poster is \frac{1}{4} yard wide and \frac{3}{4} yard tall.

To find - What is its area ?

Proof -

We know that ,

The area of rectangle = Length × Breadth

Here,

Given that,

Length of rectangle = \frac{3}{4} yard

Breadth of rectangle = \frac{1}{4} yard

∴ we get

Area of rectangular poster = \frac{3}{4} × \frac{1}{4}  yard²

                                          = \frac{3}{16} yard²

⇒Area of rectangular poster = \frac{3}{16} yard²

Which is the largest atomic radius
katrin2010 [14]

Answer:

₁₁A

Explanation:

Atomic radius

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons.

This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases.

So in given elements consider A₁₁, B₁₂, C₁₃ ans D₁₇ as sodium, magnesium, aluminium and chlorine. This is the third period and as we move form sodium to chlorine atomic radius decreases. That's why sodium has greater size.

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased

The buildup of sediment where a river empties into a slow-moving or nonmoving body of water is known as a/an
777dan777 [17]

The buildup of sediment in which a river empties right into a slow-transferring or non transferring frame of water is referred to as a Delta.

<h3>What is Delta ?</h3>

Deltas are wetlands that shape as rivers empty their water and sediment into some other frame of water, together with an ocean, lake, or some other river.

A form of soil made nearly completely of windblown sediment is referred to as Loess.

The natural count number in soil comes from decaying flora and animals and their waste products.

Clay, that's made of tiny debris and drains water very poorly, is one of the essential additives of soil.

A form of soil referred to as peat is maximum probably to shape in a/an Coastal surroundings in Tropical placing.

Water enables withinside the improvement of soil with the aid of using carrying Mineral and vitamins from higher layers to decrease layers.

The Richness of nutrients from soil is not unusualplace in moist environments, like rain forests.

Quartz-wealthy determine cloth results in the improvement of Sandy soils.

The layers of soil composed specifically of natural count number are referred to as the O and A horizon.

A layer of soil wherein clay, iron, and different factors from the overlying soil accumulates is referred to as the B horizon, or subsoil.

  • Delta is stated to be a frame of sediments deposited whilst a river flows into a status water, together with the ocean or a lake.

  • Loess are wind blown deposits of silts and clay composed of quartz, feldspar and different minerals . Loess dominantly have excessive porosity.

  • Organic subjects compose specifically of stays of animal and flora . After this flora and animals dies they shape natural count number that provides to soil vitamins.

  • Clayey soil represent very tiny debris which have a bad draining cappotential because of it tiny bad spaces .

  • Tropical placing in a coastal surroundings affords the important environments for soils like peat to shape . It has plentiful of plant stays . Moreover peat is the primary degree of coal formation, containing wet and unconsolidated plant substances.

  • Minerals part of what help withinside the improvement of the soil .And additionally it is carried right all the way down to the earth with the aid of using water thru a procedure referred to as Leaching.

  • Richness of nutrient are not unusualplace in tropical surroundings which are moist and help plentiful life.

  • Sandy soil are fashioned from dad and mom substances containing minerals together with feldspar and quartz.

  • Horizon O and A are referred to as topsoil and are specifically compose of animal and flora stays and big quantity of minerals.

  • The subsoil or B Horizons consists of mineral together with irons , clay minerals because of percolation from the pinnacle soils and it has a tendency to build up here(subsoil).
