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

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
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
The missing compound is
Explanation:
Answer:
1) Carbon dioxide is the name of the gas.
2) The missing compound is H3C2O2Na

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
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!
ALSO PLEASE KEEP IN MIND THIS IS JUST MY PREDICTION
Identify the force used on your arm when you walk a dog on a leash and it tries to chase something.
Friction
Gravity
Strong pull
Weak push
Answer: The force used on your arm when you walk a dog on a leash and it tries to chase something is known as Strong pull.Strong pull is defined a physical force which is usually aggressive orcoercive and it involves the movement in a particular direction due to different factors or reasons. The Dog in the example has a leash on and applies a force in the direction ofthe thing it wants to chase which is a perfect example of a strong pull.

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.
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.
Answer:
The first one

How are the volvox, euglena, paramecium, and amoeba similar and different in how they move, and eat?
Answer:
Both can hunt for their food (heterotrophs), but euglena can also make their own food (autotroph) with its chloroplasts. Amoeba have pseudopods to move/eat, but euglena have flagella to move. How are euglena and paramecium similar and different? ... Both also use flagella to move, but volvox move together in colonies.
