Answer:
number (12 is c) (13 is 5) (14 is 5)
Explanation:
Answer:
12:B 13: 5 m/s 14: 5 m/s
Explanation:
12: this is a position vs time graph, and that worded description matches the graph because the slope of a p vs t graph is the velocity
13: again, the slope of a position vs time graph is the velocity. 10m/2s = 5 meters a second or m/s
14: same thing. the object travels 30 m in 6 s so 30/6=5 m/s

What is the funtion of the lungs in the respiratory system? (Use complete sentences.)
Answers
Answer:
The lungs' main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. Help is required from structures outside of the lungs in order to breath
Explanation:
Explanation: The lungs are the most important part of the respiratory system. They give air to serve the whole entire body. Lungs are one of the most vital organs of the body, since they help us breathe, and if we did not breathe, we would die.

To investigate how mechanical energy affects the number of times a ball will bounce back, Maria dropped a ball from three different heights. Which of the following would be a reasonable conclusion from this experiment?
The height from which a ball is dropped does not affect the number of times it bounces.
Increasing the height will give the ball more energy and will increase the number of times it bounces.
Increasing the height will give the ball less energy and will decrease the number of times it bounces.
Decreasing the height will give the ball more energy and will increase the number of times it bounces.
Answers
Answer:
C. Increasing the height will give the ball more energy and will increase the number of times it bounces.

The amount of matter in a given space or volume
Answers
In the given question, the amount of matter in a given space or volume is called density.
Matter is defined as any substance or anything that has mass, and which occupies space.
Density is a physical property of matter and can be defined as the mass of an object divided by its volume. Density has unit typically in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
It is an important property of matter because it helps to identify and distinguish different materials based on their mass and volume.
Therefore, density is the amount of matter in a particular region or volume.

1. What is collision theory?
2. How does collision theory relate to factors that affect reaction rate?
3. Define reaction rate.
4. List factors that influence the rate of a chemical reaction.
5. Choose one of the factors you listed in your answer to question 2, and explain how it affects reaction rate.
Answers
Answer:
This is where google becomes your best friend but I got you
Explanation:
1. A theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
2. Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.
3. The speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
4. There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
Answer:
1. a theory that says a chemical reaction takes place when particles of the reactants collide with sufficient energy to initiate the reaction
2. Increasing the concentration of the reactants, the faster the particles will collide so the reaction rate will be faster
3. a measure of how fast a reaction takes place
4. Temperature, presence of a catalyst, reactant concentration, surface area

⚠️An irregular piece of iron has a mass of 78.7 grams. When placed in a graduated cylinder with 30 mL of water, the water rises to the 35 mL ⚠️
Answers
Answer:
The density of the iron is: 15.74g/cm3
Explanation:
-To determine the density of something, you have to divide the mass and the vol.
-mass/volume = density or, m/v = d
-The mass of the iron is: 78.7 grams
-The volume of the iron is 5mL
In order to find the density, you have to divide:
m/v = d
78.7g ÷ 5mL = 15.74
