Answer:

The Nazca plate forms the southeastern part of the Pacific plate. The Nazca and the Pacific plate share both divergent and transform type of plate boundary. The Pacific and the Nazca plate are separating at an increasing rate of about 122-142mm/year. These are the regions where the rate of tectonic activity is very high.

The Nazca Plate and the South American Plate are also converging at a rate of about 62mm/year, being the fastest subduction rate on earth.

The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise.The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries.

Emily wanted to see what battery lasted the longest. She put each battery into a clock and recorded the time that the clock stop

Andru [333]

Answer:

independent variable -- different batteries

dependent variable -- the time that clock stop

Explanation:

In an experiment or a research study, there are two type of variables that can affect the result of the experiment or the conclusion. They are independent variable and the dependent variable.

An independent variable may be defined as that variable in an experiment which can be changed or can be controlled in the scientific experiment in order to test the effect on the dependent variable. It cannot be changed by other variables.

On the other hand, dependent variable are those are those which can be altered or change that can affect the experiment.

In the context, Emily uses the different types of the batteries as an independent variable and the time where the clock stopped in the dependent variable in her research.

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).

Calculate the osmotic pressure associated with 50.0 g of an enzyme of molecular weight 98 g/mol dissolved in water to give 2600

andrew-mc [135]

Answer:

π = 4,882 atm

Explanation:

To calculate the osmotic pressure (π), the <em>Van´t Hoff equation</em> must be used, which is:

π x V = n x R x T

<em>Where: </em>

• π: Osmotic pressure, which is the difference between the levels of the solution and the pure solvent through a semipermeable membrane, which allows the passage of the solvent but not the solute

• V: Volume of the solution, in liters unit

• n: Number of moles of solute

• R: Constant of ideal gases, equal to 0.08206 L.atm / mol.K

• T: Absolute temperature, in Kelvin degrees

With the data you provide you can calculate the osmotic pressure by clearing it from the equation, we would be equal to:

π = (n x R x T) / V

However, all data must first be converted to the corresponding units in order to replace the values in the equation.

<em>Solution volume ⇒ go from mL to L: </em>

1000 mL of solution ____ 1 L

2600 mL of solution _____ X = 2.6 L

Calculation: 2600 mL x 1 L / 1000 mL = 2.6 L

<em>Temperature ⇒ Go from ° C to K </em>

T (K) = t (° C) + 273.15 = 30.0 ° C + 273.15 = 303.15 K

<em>Number of moles of solute ⇒</em> <em>It can be calculated since we have the mass of the enzyme and its molecular mass: </em>

98.0 g of enzyme ____ 1 mol

50.0 g of enzyme _____ X = 0.510 moles

Calculation: 50.0 g x 1 mol / 98.0 g = 0.510 moles

Now, you can replace the values in the Van´t Hoff equation and you will get the result:

π = (n x R x T) / V

π = (0.510 mol x 0.08206 L.atm / mol.K x 303.15 K) / 2.6 L = 4.882 atm

Therefore, <em>the osmotic pressure will be 4,882 atm</em>

_______ is the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Kelvin. A. A calorie B. En

Maksim231197 [3]

<h2>The required option d) "specific heat" is correct.</h2>

Explanation:

To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
Thus, the required "option d) specific heat" is correct.
