What happens to potential energy when you move against the magnetic force?

Answers

Answer:  The field produces a repulsive force pushing them apart. They repel each other. In this case, the closer they are, the higher their potential energy will be. If allowed to move, they may move as far apart as possible or one will swing around to change its orientation.

EASYYYYYYYYYYY A batter hits two balls during practice. Ball A travels 10 meters, while ball B travels 12 meters. The batter decides to hit ball A with less force. How will this change the motion of ball B?

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.

PREDICT: Which do you think would be the most adhesive and least adhesive to wax paper and why do you think this?
A) oil

B) Isopropyl alcohol

C) tap water

D) soapy water

Answers

The answer is B!!!!!

Answer:

Tap water would be the least adhesive to wax paper.

Oil would be the most adhesive

Explanation:

If you get wax paper and water right now, it will repel the water. Putting wax on anything makes it water repellent. I don't know how but this is just my prediction.  

I feel like oil would be the most adhesive because oil repels water, so does wax paper. So I'd predict oil would hold onto wax paper the most.

Hope this helps!

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.

When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and water; a salt, water and carbon dioxide are produced. In two or more complete sentences, describe how your knowledge of balancing chemical equations can help you to determine the missing compound.


NaHCO3 + HC2H3O2 ⟶ ________ + H2O + CO2

Answers

Answer:

1) Carbon dioxide is the name of the gas.

2) The missing compound is  

Step-by-step explanation:

1)When ever an acid reacts with baking soda brisk effervescence of carbon dioxide gas are released.

So, when citric acid reacts with baking soda it gives salt of sodium citrate , water and carbon dioxide gas.

2)

According to law of conservation of mass:

Number of atoms on reactant sides are equal to the number of atoms on product side.

Number of atoms of an element on left hand side is equal to the number of atoms of that same element on the right hand side.

Number of hydrogen atom on reactant side = 5

Number of hydrogen atom on product side = 2+ x

5 = 2+x

x = 3

Number of carbon atom on reactant side = 3

Number of carbon atom on product side = 1 + y

3 = 1 + y

y = 2

Number of oxygen atom on reactant side = 5

Number of oxygen atom on product side = z + 3

5 = z + 3

x = 2

Number of sodium atom on reactant side = 1

Number of oxygen atom on product side = a

1 = a

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.
