Your team is provided with two test materials, C and D. You test the two materials using the air hockey table to collide Object A with Objects C and D. The test material objects are the same size and shape and are very similar in mass. The results are shown in the diagram. The sizes of the arrows are proportional to the acceleration.
Apply Newton’s laws to determine which of these materials is more suitable as a liner for a safety
helmet. Explain your answer.
Answer:
the annswer is b
Explanation:
just look at the questin and then see wicth one you can cross off
The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact. The materials is more suitable as a liner for a safety helmet exists B.
What is meant by Newtons law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact. The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion. First Law of Motion of Newton Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace.
According to the first law, unless a force acts on an object, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction forces upon one another.
The materials is more suitable as a liner for a safety helmet exists B.

Firmly hold with one hand the end of a ruler (or similar object) over the edge of a table. Pull the other end down gently and listen to the sound. Then give the ruler (or similar object) a harder downward pull, and see if there is a difference in sound. Describe what you hear and explain the difference using the terms “energy,” “amplitude,” “intensity,” and “decibel.”
2. Take some time to listen to sounds in your environment. Make a list of ten sounds, ranking them from the highest pitch to the lowest. Write a couple of sentences describing whether this was easy or difficult and why. (Some of the sounds can come from tapping objects that vibrate or playing musical notes on an instrument.)

Answer:
#1. the organs of the nervous system: This system is made up of the brain, spinal cord
#2. the organ that sensory nerves reach the brain: Sensory neurons assemble to form sensory nerves that reach the brain through the spinal cord. The brain processes the sensory impulses and sends information to the corresponding effector organs through motor nerves
The small finger like projections are: axon terminals, The connection between a neuron and a muscle cell is called a neuromuscular junction. The finger-like projections of the axon are the axon terminals. An action potential moves down to the axon terminals where it causes a chemical message called a neurotransmitter to be released into the synaptic cleft.

Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.

On the average, how much energy is lost from each trophic level? explain why
Answer:
I think it's 10% because some of it turns into heat energy
Explanation:
On average, about 90% of the energy is lost from each tropic level. The remaining 10% is available for the next trophic level.
The tropic level of the organisms is the position of organisms occupied in the food web. When an organism consumes other organisms as its food, the energy stored in the form of chemical energy in the organic molecules is converted into the energy used for cellular respiration.
This conversion is not efficient and the energy is lost in the form of heat. Some of the energy is used for growth and maintenance. While other energy is excreted.
Thus, when an organism consumed organic matter, 90% of the energy is lost and 10% of the energy is involved in the building of body tissues. This 10% of energy is passed to the next level.

Sammie is using radiocarbon dating to determine the age of a sample of objects. Which best explains why radiocarbon dating can be used to determine the accurate age of these items?
A. They contain radioactive isotopes that decay at a constant rate.
B. They are made primarily of radioactive carbon that is easy to detect.
C. They give off radioactive isotopes when an electrical charge is applied.
D. They have been exposed to large amounts of radioactivity in the atmosphere.
Answer: I think the correct answer is A or B.
Explanation: But i highly suggest B
Radiocarbon dating is a feasibe method because the isotopes involved decay at a constant rate.
What is radiocarbon dating?The term radiocarbon dating refers to the use of carbon in the establishment of the age of a sample. This is usually done by the use of carbon -14 isotope.
The reason why radiocarbon dating can be used to determine the accurate age of these items is that they contain radioactive isotopes that decay at a constant rate.

2. What is the value of the WAVELENGTH for WAVE A?
Answer:
Sorry I really just needed the points ;(
Explanation:
Answer:
1) Amplitude of wave A: 0.5 meters
2) You would have to find the wavelength with the equation λ = [tex]\frac{v}{f}[/tex]
Explanation:
1) Amplitude of a wave is the height of the wave from the horizontal line drawn on "0" to the highest point on the wave.
2) λ is lambda, sign for the wavelength. V is the velocity of the wave, and F is the frequency of the wave.

If a fossil contains 50% of the amount of carbon that a living animal contains, how many half lives have passed while it decayed? How old is the fossil? (half lives x 5730)
The currently accepted value for the half-life of 14C is 5,730 years. This means that after 5,730 years, only half of the initial 14C will remain; a quarter will remain after 11,460 years; an eighth after 17,190 years; and so on.

Limiting factors are divided into two categories. What are they? Give an example of each.Limiting factors are divided into two categories. What are they? Give an example of each.
Answer:
Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. These names mean just what they say: Density-independent factors have an impact on the population, whether the population is large or small, growing or shrinking.
the density-dependent factor example is:
Density-dependent factor, also called regulating factor, in ecology, any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area).
the independent factors example is:
Pollution. Like other density independent factors, pollution is a good example of a density independence.
