Which scenario best describes motion?
A. a toy train in position 4 on a number line
B. a race track that is 100 meters long
C. a ball rolling from point A to point B
D.a student living 150 miles from Chicago
Answers
The scenario which best describes motion is a ball rolling from point A to point B as it is moving.
What is motion?Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.
Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.
Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic mechanics is based on modern kinematics.

Do you have quantitative data (numerical results or calculations)? Do you have qualitative data (written observations and descriptions)? How can you organize this date for your report?
Lab-Motion
Answers
Answer:
this is what I put, I should also mention I got 100% so I doubt its wrong
Explanation:
Newton's second law is a quantitative description of the changes that a force can produce in the motion of a body. "It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it". The momentum of a body is equal to the product of its mass and its velocity. I can include this information in the report or a more detailed version that can make up about 60% of Newton's second law explanation.

A The action of his foot striking the ball and the reaction of the ball against his foot.
B The mass of the ball being accelerated from rest by the kicker.
C Air friction slowing the ball as it is flying through the goal posts.
D All of these.
Answers
Answer:
The moment the ball leaves the foot, it stops accelerating, and from this point forward only two forces are exerted upon it: the friction with the air, which slows the ball's motion, and gravity, which pulls it down. As the ball moves, it slows and falls down.

Use complete sentences to differentiate between acids and bases on the basis of touch. Give an example of each type.
Answers
Answer:
There are several theories to explain the difference between an acid and a base. One of the most complete theories is Lewis's theory, because it encompasses several compounds that other theories do not include. According to Lewis's theory, an acid is a substance capable of accepting a pair of electrons. And Lewis bases are substances that have the ability to donate a pair of electrons.
An example of an Lewis acid-base reaction is ammonia and boron trifluoride:
BF3 (is the acid) + NH3 (is the base) → H3N - BF3
Some differences of acids and bases to the touch are:
• Acids are sour in taste while Bases are bitter in taste. This is due to the pH that indicates acidity or basicity, and is defined as the hydrogen potential of a solution. The pH indicates the concentration of hydrogen ions in a substance. Substances with pH less than 7 are considered acidic, while substances with a pH greater than 7 are considered as bases (alkaline).
• Acids are highly corrosive, and can cause chemical burns to the skin, or respiratory damage when inhaling their gases. An example is sulfuric acid (H2SO4), which can corrode steel. The bases instead have a feeling of soap or slippery to the touch.
• Acids react with metals to produce compound and hydrogen gas while bases do not react with metals. For example, copper is attacked by nitric acid by reaction:
Cu(s) + 4HNO3(aq) ⇒ Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
• Acids turn blue litmus paper into red whereas in case of Bases they turn red litmus paper into blue.
• The bases are irritating to the skin, as they dissolve the skin fat, and can destroy organic matter by its caustic effect. An example is Sodium Hydroxide (NaOH)
• Acid and bases are good conductors of electricity in aqueous solutions.
Explanation:
HOPE THIS HELPS
Answer:
Acids can burn your skin when touched because acids are highly corrosive, whereas bases are slimy and have a slippery feel. An example of an acid is citric acid, which can be used as a disinfectant or in foods and candies as a flavor enhancer. Bleach is an example of a base and is used for cleaning and has whitening properties.

What important role do sand dunes play?
Answers
Answer:
Keeps tides on the shore and away from the city
Explanation
Sand dunes are essential in coastal areas due to their significant roles. They act as natural barriers, protecting coastlines from erosion and storm surges. These dunes offer unique habitats for specialized plants and animals adapted to sandy environments.
Moreover, they contribute to groundwater recharge by collecting and storing rainwater. Their presence reduces wind erosion and serves as windbreaks, creating more stable conditions. Touristically, sand dunes attract visitors for activities like hiking and sandboarding, benefiting local economies.
The root systems of dune plants stabilize the soil, preventing further erosion. Overall, sand dunes are vital for coastal ecosystem maintenance, biodiversity support, and the well-being of both nature and human communities.

Which statement most likely describes the relationship between ethylene and polyethylene?
Answers
Answer:
Ethylene use falls into two main categories: 1) as a monomer, from which longer carbon chains are constructed, and 2) as a starting material for other two-carbon compounds. The first of these is the single largest use of ethylene, consuming about one-half of the annual output. Polymerization (the repetitive joining of many small molecules into larger ones) of ethylene gives polyethylene, a polymer having many uses, particularly in the production of packaging films, wire coatings, and squeeze bottles. When polymerization is carried out at high pressures and temperatures, the product is called low-density polyethylene and has properties different from the high-density polyethylene formed by polymerization under Ziegler-Natta catalytic conditions (see industrial polymers).

Write an explanation to a 5-year-old child how rain is formed referring to the water cycle. Use terminology appropriate for this age group.
Answers
Answer:
The water from the ground rises to the sky and makes clouds. When the clouds become dark then rain or snow fall to the ground.
Water droplets make up clouds. These water droplets fall to Earth as rain when they get too heavy to remain suspended in the cloud.
Why does Earth produce rain?Droplets of water make up clouds. Water droplets become larger when they condense onto one another within a cloud. Raindrops descend to Earth when these water droplets become too heavy to remain suspended in the cloud.
Why is rain significant to Earth?The water cycle on Earth, which is essential to all life, includes both rain and snow as important components. The principal method that water from the heavens falls to Earth is through rainfall, which also replenishes underground aquifers and hydrates plants and animals as well as fills our lakes and rivers.

If heat or energy is absorbed during a chemical reaction, then the reaction is considered:

Answers
If heat or energy is absorbed during a chemical reaction, then the reaction is considered as an endothermic reaction. The enthalpy change of an endothermic reaction is positive.
What is an endothermic reaction ?The reaction in which heat energy is absorbed by the reactants is called an endothermic reaction. The enthalpy change in an endothermic reaction is positive.
The reaction in which heat is evolved from the system to the surroundings is called an exothermic reaction in which the enthalpy change is negative.
By absorbing heat energy, reactants becomes energetic enough to overcome the barrier potential of the reaction. Therefore, the potential energy diagram of an endothermic reaction will show less energy for reactants than that of products.
