Answer:

The feedback mostly on the scenario mentioned is defined downwards.

Explanation:

There seem to be forces that regulate the whole mechanism as well as preserve equilibrium in every natural cycle. It is possible to divide these variables into two simple types:

The improvement throughout the natural state is attempted by negative factors as well as the positive reinforcement attempts to mitigate this improvement and approach the problem to something like the primary comfortable position.

Let's take a basic example including its process for suggestions. Users start whimpering if you get too cold. Your body continues to pump additional blood attributable to the whole shivering and indeed the temperature therefore raises. Throughout this circumstance, the temperature drop is a mechanism that serves to initiate the shivering, as well as the shivering attempts to recover the steady body’s temperature. Therefore the shivering case seems to be positive feedback that seeks to restore the primary balance.

Much the same for the landmass uplifting allows the emergence of more life above it. So, social advancement seems to be a system of negative criticism that disturbs the equilibrium. After that, the main elevation of the landform needs to regain the excess volume of degradation. So, this is indeed a tool for constructive feedback.

Answer: Gravity

Explanation: The answer is gravity: an invisible force that pulls objects toward each other. ... So, the closer objects are to each other, the stronger their gravitational pull is.

Bowling ball

Explanation:

They are traveling at the same speed, but the bowling ball has more mass.  The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.

Answer:

Explanation:

As a ball rolls downhill, its potential energy from its height is converted into kinetic energy of its motion. Potential energy is given by mass x gravity x height. So for the same height, a ball with higher mass will have more energy. A bowling ball is heavier than a soccer ball and will have more energy.

The Theory of Continental Drift says that the continents were once joined together and are drifting apart, Alfred Wegener is given credit for coming up with this theory.

Continental drift is a kind of illusion in which it looks like that continents changes their places over the surface of the earth. The Theory of Continental Drift was given by Alfred Wegener, it is a hypothesis and according to this theory the continents will move with respect to the geological time relative to each other. And due to their movement on the non planar or dynamic geographical base it looks like a drift.

Hence, option (2) is correct i.e. Alfred Wegener gave this theory.

Answer:

V2 = 0.465

Explanation:

To solve this question, we need to follow the equation below:

P1V1 = P2V2

We know that:

V1 = 500ml = 0.5L (must be convert to L)

P1 = 742 torr (must be convert to atm by divided by 760) = 0.976 atm

P2 = 795 torr = 1.05 atm

V2 = ?

P1V1 = P2V2

0.976 x 0.5 = 1.05 x V2

0.488 = 1.05 x V2

(Divided by side by 1.05 to get rid of it)

V2 = 0.465

Stoichiometry can be used to determine the molality, molarity and volume of substances in a reaction.

The term concentration refers to the amount of substance present in a solution.

1. Number of moles of NaCl = 142.8 g /52 gg/mol = 2.7 moles

Molarity =  2.7 moles/  2.3 L = 1.17 M

2. 67.5 % of magnesium chloride implies 67.5 g of MgCl2 in 100 g of solution.

Number of moles of MgCl2 = 67.5 g/95 g/mol = 0.7 moles

molality = 0.7 moles/32.5 * 10^-3 = 21.5 m

3. Number of moles of the sugar = 62.5 g/342 g/mol = 0.18 moles

Number of moles of water = 250 g/18 g/mol = 13.9 moles

Since 1 g of water = 1 cm^3 water

Molarity =  0.18 moles/250  * 10^-3 = 0.72M

Molality =  0.18 moles/250  * 10^-3 = 0.72m

Mole fraction of sugar = 0.18/(0.18 + 13.9 ) = 0.01

Mole fraction of water =  13.9 /(0.18 + 13.9 ) = 0.99

4. A 48% solution of HCl contains 48 g of HCl in 100 g of water.

Number of moles of HCl = 48 g/36.5 g/mol = 1.3 moles

Number of moles of water = 52g/18 g/mol = 2.9 moles

Mole fraction of HCl = 1.3/(1.3 + 2.9) = 0.31

Mole fraction of water = 2.9/(1.3 + 2.9) =0.69

5. 1.75 mol  =  0.770 M  * V

V =  1.75 mol/0.770 M

V = 2.27 L

The mass in grams of 4.60 mol of nitrogen is 129g.

Mass of any substance will be calculated by using their moles as:

n = W/M, where

W = required mass

M = molar mass

Given molar mass of nitrogen (N₂) = 28.02 g/mol

Given moles of nitrogen (N₂) = 4.60 mole

On putting these values on the above equation and calculated for W, we get

W = (4.60 mol)(28.02 g/mol)

W = 128.89g = 129g

Hence the required mass is 129g.

You would have to convert the algorithm to a broken down version of the compound.

NH4NO3(aq] → NH+4(aq] + NO−3(aq]

The ammonium is removed for this case, concentration gets broken down to zero.

So here, if 1 liter is equal to 10 x 10 x 10 milliliters...

use the formula of n and c to help you figure out the moles.

C is equal to N divided by V, so in that case...

N equals C times V.

C times V is 0.425, or 17 over 40 in simplest form.

From there, multiply 17 over 40 by the current moles, cross out the liters, and multiply by 335, then, 10 to the power of -3. You have to flip it to negative, because it will cancel out either way. Change the equation by the liters, and you have 0.125

Hence, your correct answer is 0.125
