Answer:
renewable resource
Explanation:
The sustainable yield of a resource is the highest rate at which we can use a renewable resource without reducing its available supply.
The amount of resources that can be harnessed without any effect on resource falls into this category. In exploiting renewable resources balance between the available resource and usage must be attained. This helps to conserve such limited resource.A common misconception people have is that sugar is energy and energy is sugar but you know better. Create a clear explanation that could be used to clear up this misconception.
A clear explanation of misconception of sugar is energy and energy is sugar is below.
What are sugars?Sugars are the disaccharide carbohydrate, it means they are formed by the combination of two monosaccharides.
One of the component of the sugar is glucose and we know that glucose is the source of energy in our body. So, sugars are naturally present in many food substance which in turn breaks down in the glucose and their composite constituent and releases energy. But we can never compare sugar as the main source of energy or equivalent to energy.
Hence, Energy means sugar is the misconception.

7. Calculate the amount of energy required heat 100.g to
H2O(s) changes to H2O(l) at 0°C
Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g
Unknown:
Amount of energy = ?
Solution:
This is a phase change process from solid to liquid. In this case, the latent heat of melting of ice is 3.33 x 10⁵ J/kg.
So;
H = mL
m is the mass
L is the latent heat of melting ice
Now, insert the parameters and solve;
H = mL
mass from gram to kilogram;
100g gives 0.1kg
H = 0.1 x 3.33 x 10⁵ = 33300J

Which of the following are found as the lithosphere moves a volcano away from a mantle plume?
a- sea mounts
b- lithospheric mountains
c- subduction zones
d- none of these
Answer:
c- subduction zones
Explanation:
A mental plum is generally found within the mantel and is a mechanism of convection, the plume is often invoked as the causes of volcanic hotspots. Such can be seen on Iceland and Hawaii islands. They represent a large volume of volcanism near the plate boundary. Mantle plumes are believed to be a source of molten magma from the earth.is density defined as the volume in a given mass orthe mass in a given volume?
Answer:
mass in a given volume
Explanation:
Density is the mass in a given volume or mass per unit volume of a substance.
Mass is defined by the amount of matter present in a substance.
Volume is the space occupied by a body.
Density is the mass divided by the volumeMathematically;
Density = [tex]\frac{mass}{volume}[/tex]

How could two objects have the same temperature but different thermal energies? One object could have more particles and greater total kinetic energy. One object could have more particles and lesser total kinetic energy. One object could have more calories. One object could have more heat.
Answer:
One object could have more particles and greater total kinetic energy
Explanation:
The higher the temperature the more the particles. So, when we have high temperature, there is more particles interacting.
Temperature can simply be defined or gotten by taking the average of of the kinetic energy of the particles in the object that is the keywords here are TAKING THE AVERAGE KINETIC ENERGY
Thermal energy is the energy that can be gotten from adding up all the total kinetic energy of the particles in the object. So, the keywords here are; ADDING UP THE TOTAL KINETIC ENERGIES.
So, when two particles of the same temperature have the different thermal energy it means that One object could have more particles and thus having greater total kinetic energy.
Newton’s second law can be written using two formulas, what are they?
Answer:
In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.

How many grams of H2SO4 do I need to use in order to produce 3.01 moles of water? consider the equation. _Ca(OH)2 + _H2SO4 = _CaSO4 + _H20
Answer:
148 g H₂SO₄
General Formulas and Concepts:
Chemistry - Stoichiometry
Reading a Periodic TableBalancing RxN'sUsing Dimensional AnalysisExplanation:
Step 1: Define
RxN: Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Given: 3.01 moles H₂O
Step 2: Balance RxN
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
Need the same amount of O's and H's on both sidesStep 3: Define conversions
Molar Mass of H - 1.01 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol
Step 4: Stoichiometry
[tex]3.01 \ mol \ H_2O(\frac{1 \ mol \ H_2SO_4}{2 \ mol \ H_2O} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )[/tex] = 147.625 g H₂SO₄
Step 5: Check
We are given 3 sig figs. Follow sig fig rules.
147.625 g H₂SO₄ ≈ 148 g H₂SO₄
In steel, what smaller atom fits into the empty spaces within the iron crystal lattice?
Answer:
The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix.whats the difference between spring tides and neap tides
Answer:
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides.
Explanation:
Answer:
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.

A scientist observes hot water erupting from a vent in the Earth.What most likely caused the water to rise and erupt from the vent? someone pls answer i if u answer u get 57 points
Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.

How does energy change form when friction causes the temperature of an object to increase?
Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy. This gives them a greater temperature, and they feel warmer.
What is friction ?The term friction is defined as the resistive force that occurs when two bodies in contact move relative to one another.
Adhesion between body surfaces, and the adhesion is the molecular force that occurs when two materials come into contact with each other are the causes of friction.
Friction is an everyday force that is generated by two surfaces when they are interacting. When these surfaces slide against each other, this interaction increases the thermal energy of the two surfaces.
Thus, Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy.
