Suppose you wish to jump horizontally and in order for you to jump a distance of 4 feet horizontally, you must exert a force of 200 N. When you are standing on the ground, you have no trouble jumping 4 feet horizontally. If you are standing in a canoe, however, and you need to jump 4 feet to reach the pier, you will surely fall into the lake. Why is it that you cannot jump 4 feet out of a canoe when you can easily do this when on land?

How are heterogeneous mixtures and solutions the same?How are they different?
Answers
Hello soysans!
Heterogeneous mixtures and solutions are, well....mixtures.
Solutions are a type of homogeneous mixtures.
Now, what are homogeneous mixtures? Homogeneous mixtures are mixtures that are uniformly spread throughout. They have an even distribution of components. The particles are soluble & too fine to be seen be seen by the naked eye.
On the other hand, heterogeneous mixtures are mixtures that are non-uniformly spread throughout. They have an unequal composition & the particles are big enough to be seen by the naked eye.
Solutions (homogeneous mixtures) & heterogeneous mixtures have a lot of similarities & dissimilarities between them.
Similarities (How are heterogeneous mixtures and solutions the same?) :
Homogeneous mixtures & heterogeneous mixtures are mixtures, i.e, they are made up of 2 or more particles/components mixed together.Dissimilarities (How are they different?) :
Heterogeneous mixtures are non-uniformly scattered while homogeneous mixtures are uniformly scattered.Heterogeneous mixtures have huge particles while particles in homogeneous mixtures are very small.Heterogeneous mixtures can scatter light (tyndall effect) but homogeneous mixtures cannot.___________________

Electron transfer occurs at an electrode of a galvanic cell
A Galvanic cell converts chemical energy into electrical energy.
There are two electrodes in a galvanic cell which are anode and cathode. The electrodes is where electron transfer occurs.
The anode is the electrode at which the oxidation (loss of electron) occurs whereas the cathode is the electrode at which the reduction (gain of electrons) occurs.

Distinguish between efficiency and mechanical advantage.
Answers
Answer:
I think the answer is Mechanical advantage is a measure of how much your force is multipled efficiency is measure of how much of the work you do actually goes to moving the thing you are trying to move.
Adding more pulleys may increase the mechanical advantage but, it also increases the amount of extra stuff you are moving.

What is the importance of water?
Answers
IMPORTANCE:
Water is very important. Whether it's from washing your dishes to hydrating, to simply just watering your flowers, water is important.
Washing Dishes
When you eat, after you eat, you wanna clean your dish. You're not gonna keep it dirty, you're going to have to wash it. Soap and water are often used when washing dishes. It's the best way to get it cleaned.
Hydration
Drinking water can have many benefits. It can make you more productive, you can even lose weight, no migraines, and it can boost your metabolism.
Watering Flowers
It's helpful to water plants because watering them on a basis/routine can help them gain nutrients. No watering the plant can result the plant drooping down and for it to become droopy and dry.

Atoms will combine with each in order to become more chemically stable. Compounds are formed between two atoms that have
drag and drop answer here outer energy levels. The two types of compounds that can be formed between atoms are ionic and covalent.
Ionic compounds are formed between two drag and drop answer here charged atoms. Ionic compounds contain a drag and drop answer here ion and a
drag and drop answer here ion. Metals will lose electrons to form positive ions and nonmetals will gain electrons to form negative ions. These
oppositely charge ions are very attracted to each other and form very strong bonds as a result. Ionic compounds are characterized by crystalline
structure, drag and drop answer here melting and boiling points, and are drag and drop answer here at room temperature.
Two drag and drop answer here will combine to form covalent compounds. Covalent compounds are formed when two atoms drag and drop answer here
one or more pairs of electrons. The force of attraction between the nonmetals is relatively weak. Covalent compounds are characterized by
drag and drop answer here melting and boiling points and can be gases, liquids, or soft solids at room temperature.

calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?
Answers
Answer: 0.25 moles NH3
1.51x10^23 molecules NH3
Explanation:
5.6dm3 (cubic decimeters)
1 dm^3 = 1 liter
We have 5.6L of ammonia (NH3 gas) at STP. All gases at STP occupy 22.4 liters/mole. Use this information as a conversion factor:
(22.4 L NH3)/(mole NH3)
Therefore:
(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3
Use Avogadro's number to convert moles to particles/molecules
(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3
