Answer:
The energy of a wave is transferred to the material it encounters. Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Explanation:
Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.
What does it mean for a wave to be absorbed ?When a wave is absorbed, matter absorbs energy from the wave, lowering its amplitude. When a sound wave strikes foam padding, for example, the energy passes through the material and is sometimes converted into heat or other forms of energy.
The energy of a wave is transferred to the particles in the surface when it is absorbed by a surface. This usually causes the particles' internal energy to increase.
Some wavelengths or colors of light are absorbed when white light shines on an opaque object.
Thus, Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.

Carbon atoms in diamond are arranged in connecting cubes. Carbon atoms in charcoal are arranged more randomly. Using the names of the structures a solid can have, describe the differences between these forms of carbon.
Answer: Charcoal is the charred product from pyrolyzing wood. Charcoal is a porous material that can burn or adsorb pollutants, carbon atoms in diamond are arranged in the same way something in the solid state of matter would be arranged- like building blocks. if the carbon atoms in charcoal are arranged more randomly but still close
together, thats similar to the way a liquid would look!
Answer:
The carbon atoms in diamond are arranged like building blocks in the solid state of matter, whereas the carbon atoms in charcoal are arranged more randomly but still close together.

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.
Answer:
Increasing the height will give the ball more energy and will increase the number of times it bounces.

Answer:
A compound is a molecule made of atoms from different elements
Explanation:
All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.

An athlete runs at an average speed of 9.00 mph. If she wants to complete a distance of 42.19 km, she must jog for ____ x 10^2 min.
Fill in the blank.
The athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.
To find the time the athlete must jog, we'll first convert the distance from kilometers to miles, then use the formula:
Time (in hours) = Distance ÷ Speed
1 kilometer is approximately 0.621371 miles.
So, the distance in miles is:
42.19 km × 0.621371 miles/km ≈ 26.21875 miles
Now, we can find the time in hours:
Time (in hours) = 26.21875 miles ÷ 9.00 mph ≈ 2.9131944 hours
To convert hours to minutes, multiply by 60:
Time (in minutes) ≈ 2.9131944 hours × 60 min/hour ≈ 174.79167 minutes
Now, let's round this to two decimal places and express the result in scientific notation:
Time (in minutes) ≈ 174.79 minutes
To write it in the requested form (using scientific notation), we move the decimal point two places to the right:
Time (in minutes) ≈ 1.7479 × 10 minutes
So, the athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

Can anyone help me with these science questions?
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.
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

Cuticles are protective lining in the epidermal layer of plants. Cuticles helps to reduce water loss and protect the plants from environmental stresses.
What is cuticles?Cuticle is an organism's external layer or area that makes touch with the environment. The epidermis secretes the dead, noncellular cuticle in many invertebrate species. In humans, the cuticle is the epidermis, and this layer may include colours and chitin, similar to arthropods.
The cuticle is a protective coating that protects the epidermal cells of leaves and other organs while preventing water loss in some higher plants.
It is made up of cutin, a waxy, water-repellent compound related to suberin that is present in the corky tissue's cell walls. Hence, option c is correct.
