2) The gear system of a car: The gear system of a car can only take whole number integer values. It is not continuous and only one level of gear can be attained at a given time.
The two analogies that I used to describe quantized change are;
- Notes on a Piano
- Digital Clock
Quantized change is simply means that the change is definite under certain restrictions such as the gears in our cars. This means that change comes in discreet amounts.
The 2 analogies that I can use to describe it are as follows;
1) Notes on a Piano; When we are turn on a piano, the notes on the piano are fixed and as such we can only play the notes that the keys can hit.
2) Digital clock; The representation of time in digital clocks is in terms of numbers which can be said to be discrete variables.

Base your answers to questions on the food web below and on your knowledge of science. Answer each part below. A. Which organism labeled in this food web provides energy, either directly or indirectly, to all of the other organisms? Explain why this is your answer. B. Explain why the amount of food available to the slug population might increase if the aphid population decreased.
Answer A:
The organism which provides energy directly and/or indirectly to all of the other organisms is the garden plants.
Explanation:
Plants are generally found at the lowest part of the pyramid/food chain. They are also called Autorotrophs because they are the primary producers of energy from which the entire pyramid feeds off.
The other animals/organisms on the pyramid are called Heterotrophs because they depend directly or indirectly on the primary energy producers.
Answer B:
The Slug and the Aphid feed are herbivorous. So they are in competition for the garden plants. If one of them, for some reason, decreased in population, the other will have more food to eat.

Using dimensional analysis How many mg are there in 8.75 X 107 kilograms?
Conversion factors:
[1000 g = 1 Kg]
[1000 mg = 1 g]
Can you please show the work
Answer:
8.75×10¹³ mg
Explanation:
From the question given above, we obtained:
Mass (in Kg) = 8.75×10⁷ Kg
Mass (in mg) =?
Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:
1 Kg = 1000 g
Therefore,
8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg
8.75×10⁷ Kg = 8.75×10¹⁰ g
Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.
Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:
1 g = 1000 mg
Therefore,
8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g
8.75×10¹⁰ g = 8.75×10¹³ mg
Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.
The difference between a mixture and a solution is that mixtures cannot be easily separated. True O False.
Answer:
False
Explanation:
Mixtures are a solute and solvent that are not chemically combined, therefore easily separated. Solutions are a solute and solvent combined together.
Can somebody please explain the heat formula to me? q=mcΔt
Thank you!!
Answer:
Explanation:
It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius. ... The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.
Answer:
The formula q=mcΔt explained below
Explanation:
so q represents the amount of heat energy. M is the mass of the object and c is the temperature of the object. Δt also known as delta is the change in temperature. It would be the final temperature minus the original temperature.

The ________ the handle of a wrench, the _________ the mechanical advantage.
longer, greater
shorter, greater
shorter, less
shorter, less
Answer:
longer, greater;
Explanation:
This is more of a physics question. Refer to any notes you might have on simple machines. In short though, a wrench with a longer handle requires less force to be used than a wrench with a short handle. As a result it has more mechanical advantage.
The answer "shorter, less " could also be correct but it's listed twice so I wouldn't pick it.
Answer:
long,great
Explanation:
An ion has an overall charge of -2. Its the nucleus is made up of 29 protons and 35 neutrons. How many electrons does the atom have?
Answer:
31 electrons.
Explanation:
Atoms initially have a neutral charge. So if this atom were neutral, it would have 29 electrons to balance out with the 29 protons. Protons are never added or removed. Since this atom has a -2 charge, that means it is an anion with 2 additional electrons. 29e- + 2e- = 31e-
Calculate the average atomic mass of a
sample of lead that is 24.1% lead-206
(205.974 amu), 22.1% lead-207 (206.976 amu)
and 53.8% lead 208 (207.977 amu).
Answer: 207.217 amu
Work:
203.973 amu *(0.014) = 2.855 amu
205.974 amu *(0.241) = 49.639 amu
206.976 amu *(0.221) = 45.741 amu
207.977 amu *(0.524) = 108.979 amu
2.855 + 49.639 + 45.741 + 108.979 = 207.217amu
Explanation:
The average atomic mass has been defined to be the total mass given by the relative abundances and masses of the isotopes. The average atomic mass of lead is 204.359 amu.
What is average atomic mass?The average atomic mass has been given by the masses and relative proportions and abundances of the isotopes of the elements that differ from the mass of the element in the periodic table. It is the average mass given by the sum of the masses and the abundances.
Given,
Abundance of lead-206 = 24.1%
The abundance of lead-207 = 22.1%
The abundance of lead-208 = 53.8%
Mass of lead-206 = 205.974 amu
Mass of lead-207 = 206.976 amu
Mass of lead-208 = 207.977 amu
The average atomic mass is given as:
= (205.974 × 0.241) + (206.976 × 0.221) + (207.977 × 0.524)
= 49.639 amu + 45.741 amu + 108.979 amu
= 204.359 amu
Therefore, 204.359 amu is the average atomic mass.

Extended networks of pi bonds can cause a delocalization of electrons. Explain how this occurs.
Electrons in pi bonds can spread over a group of atoms. This is what is meant by delocalization of a pi bonded network.
There are two kinds of bonds in chemistry, these are;
Sigma bondsPi bondsSigma bonds are formed by end to end overlap of atomic orbitals while pi bonds are formed by side by side overlap of atomic orbitals.
Sometimes, pi orbitals are well oriented in such a way that electrons are spread over the pi orbitals of several atoms. For instance, in benzene, there are six pi electrons that are spread over the six carbon atoms in benzene. This is what is meant by delocalization.
Delocalization can only occur when there is are conjugated double bond. This is why delocalization is common in many aromatic compounds. Some inorganic ions such as CO3^2- also have delocalized pi electrons.
