Wich has more energy rolling down a hill - a bowling ball or soccer ball? Explain your answer
Answer:
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 process of erosion or landscape is an example of positive feedback. Can you describe a Feedback group that explains this process in more detail, starting with a feedback between plant, humus, and at least one more node in the network? hint: you will need to add more than one negative feedback
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:
Negative PositiveThe 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.
Throughout the present situation, erosion seems to be a constructive response throughout the landform transition scenario. This additional elevation is neutralized either by the extrusion process because as landmass becomes lifted by another process. Currently, due to the extreme interplay of several other variables, this shift in landscape height can start happening. The increased height including its landform may be caused by structural elongation of both the rock body. Another mechanism that will act to improve height becomes isostatic equilibrium.So, throughout the context of landform transition, there are several forms of negative comments. The quantity of surface accessible at this site also improves as even the landmass becomes increased. As a consequence, this additional area will be filled by new occupants. Plants as well as other species may be in certain habitats. Whenever these organisms inhabit the location, the organic chemistry created by them often induces biological weathering including its rock. This again serves as a force for the shift in the landform. This excessive precipitation induces some significant erosion at either site. Finally, this reduces the elevation including its landmass and preserves the landform's primary stabilization thereby concludes the circle.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.
True or false. Singing sounds better in large rooms.
A) False
B) True
Answer:
it's true
Explanation:
Many of the factors affecting sound quality involve how sound waves bounce around the room. The more walls, the greater chance of longer reverberation. ... Ceiling height, room width, and the number of walls all contribute to determining reverberation time. Usually the larger the room, the longer the reverb time

A container holds 500 mL of Co, at 742 torr. What will be the volume of the Co, if the
pressure is increased to 795 torr?
GIVEN
WORK
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

How many moles of ammonium nitrate are in 335 mL of 0.425 M NH4NO3?
Answer:
0.142
Explanation:
Answer:
0.142 moles.
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

A 0.770 M solution of potassium nitrate (KNO3) contains 1.75 mol of solute. Calculate the volume of the solution.
Stoichiometry can be used to determine the molality, molarity and volume of substances in a reaction.
What is concentration?
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

The molar mass of nitrogen (n2) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n2? 0.164 grams 6.09 grams 23.4 grams 129 grams
The mass in grams of 4.60 mol of nitrogen is 129g.
How we calculate mass from moles?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.
