Please look at these, i'm confused, i need the questions answered, and i need a graph or just need to know how to make the graph (idk how).

Answers

Set up a graph that shows voltage on the x axis and the number of paper clips picked up on the y axis.

When you graph anything your points are made up of an x value and a y value (x,y).

You’re going to use the voltage as your x value and the average number of paper clips picked up at that given voltage as your y value.

I’ll do the first one for you! For the 25-turn electromagnet at a voltage of 1.5V the average number of paper clips picked up was 6. Giving us the point (1.5,6) that’s what you should be graphing. Do the same for all of the others.

The motion of ball B will increase.
The motion of ball B will decrease.
The motion of ball B will stay the same.
The motion of ball B will become the same as ball A.

Answers

Answer:

The motion of ball B will increase

Explanation:

Because if you hit ball A with less force than ball B then that means that ball B will go faster because you had hit ball A will less force witch will not be as faster as ball B.

What is the difference between a homogeneous and heterogeneous mixture?

Answers

A homogeneous mixture is made up of multiple different substances. (You can see different parts)
Ex: Cereal in milk or ice in soda

A heterogeneous mixture is a mixture that is mixed well. ( you can’t see the different parts)
Ex: Rain or air
You wake up in the morning and make yourself a cup of coffee. You pour the coffee in your cup, add milk, add sugar, and stir everything together. The result is a uniform cup of caffeinated goodness. Each sip should taste and look the same.

This is an example of a homogeneous mixture. In this type of mixture, the components are evenly distributed throughout and the mixture has a uniform appearance. You shouldn't be able to pick out the individual components. Additionally, you can describe a homogeneous mixture as having only one phase. A phase is any part of the mixture that has the same chemical properties and uniform distribution of the components.


Heterogeneous

When you're eating a bowl of cereal, you are consuming a heterogeneous mixture. You can easily see the different things that make up this mixture: the milk and the cereal. Each spoonful will have different distributions of the components.

A heterogeneous mixture has components that are not evenly distributed. This means that you can easily distinguish between the different components. A heterogeneous mixture has two or more phases. This doesn't necessarily mean phases of matter, like liquid or solid. For example, a mixture of water and oil has two liquid phases. Each phase has its own distinct chemical properties.

Compare and contrast the alkaline battery and a Zinc carbon battery. put in some other facts about them too. write somewhere around 2 paragraphs.



I'll mark brainlyest to whoever has the best answer and give them 50 points for helping me.

Answers

The alkaline batteries, have a higher energy density and the time a battery can remain in storage without losing any of its capacity. Also, there is a specially designed coating inside the batteries that reduces contact resistance for greater reliability. Lastly, the alkaline cells have an extra power formula to maintain power for a longer period of time in high drain devices. Alkaline batteries provide more energy than zinc carbon batteries.

The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.

The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

5. surface tension

what do you mean by cohesion ?

cohesion is an attractive force of measure where molecules are stick to each other and it is caused by cohesive force between like molecules.

It is an intrinsic property of a molecule, derived by its shape, structure, and electric charge distribution.

When cohesive molecules are become closer to each other, the electrical attraction between these molecule holds them together.

This forces are responsible for surface tension. For example mercury is a cohesive substance, strongly attracted to each other, bead together, sticks to itself when it flows.

When cohesion and adhesion combinedly work, it will lead to capillary action.

Hence, when water climbs up the interior of a thin glass tube or the stem of a plant, Cohesion holds the water together and adhesion helps the water molecules stick to glass.

How do matter and energy move through an ecosystem?
My scientific explanation is:

Your answer should include at least 6 complete sentences to explain the claim, evidence and reasoning.
Be sure to check your grammar and spelling.

Answers

Food chains allow energy to move through an ecosystem. For example, energy is transferred from organism to organism such as the sun gives energy to grass, grass gives energy to grasshoppers when they eat grass, mice eat grasshoppers, and snakes eat mice, eagles or bigger birds of prey eat snakes. A technique discovered by Charles Elton named energy pyramids display how energy is dispersed on a pyramid starting from producers to tertiary consumers. An example of a producer would be grass, primary consumer would be a grasshopper (herbivores), a secondary consumer would be a mouse/mice (eat herbivores), and a tertiary consumer (eat secondary consumers) would be an owl. Starting from the bottom of the energy pyramid (producers) to the top (tertiary consumers) it 10% of energy is available to travel up the pyramid. That is your scientific explanation!

I have 11 protons, which element am I?
A. Silicon
B. Fluorine
C. Argon
D. Sodium

Answers

D. sodium is the correct answer

Answer:

D. Sodium

Explanation:

We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?

Answers

Answer:

the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Answer:

[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).

In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.
