Explanation:
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.

The cells in the human body are like little factories. In order to grow, repair, and live, the cells need supplies. Which body systems help these cells get the energy they need?
A) circulatory system and immune system
B) digestive system and excretory system
C) circulatory system and digestive system
D) respiratory system and excretory system
Answer: A) circulatory system and immune system
Circulatory system and digestive system are the body systems which will help these cells get the energy they need.
What is Digestive system?
These are parts of the body which are involved in the breakdown of food to form energy and other compounds.
Circulatory system on the other hand ensures the nutrients are transported to other parts of the body which is why option C was chosen.

Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

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

At room temperature, aluminum is a solid and water is a liquid. How do the particles of the solid aluminum compare to the particles of the liquid water?
A. The particles in the liquid water and the solid aluminum are the same. They both vibrate and move slowly.
B. The particles in the solid aluminum vibrate and are tightly packed, and the particles in liquid water slide past each other.
C. The particles in the liquid water vibrate and are tightly packed and particles in the solid aluminum slide past each other.
D.The particles in the solid aluminum are close together with no regular arrangement, and the particles in the liquid water are well separated with a regular arrangement.
Answer:
B
Explanation:
The particles in the solid aluminum vibrate and are tightly packed, and the particles in liquid water slide past each other. The particles in the liquid water vibrate and are tightly packed and particles in the solid aluminum slide past each other.

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
If you need an explanation, please ask. I hope this helps! :)
