Answer: law of motion
Explanation:
Newton’s first two laws of motion explain how the motion of a single object changes. If the forces acting on the object are bal- anced, the object will remain at rest or stay in motion with con- stant velocity. If the forces are unbalanced, the object will accelerate in the direction of the net force. Newton’s second law tells how to calculate the acceleration, or change in motion, of an object if the net force acting on it is known.
Newton’s third law describes something else that happens when one object exerts a force on another object. Suppose you push on a wall. It may surprise you to learn that if you push on a wall, the wall also pushes on you. According to Newton’s third law of motion,

Answers
Answer:
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.

Give reasons :
a) Nylon clothes should not be worn in the kitchen.
b) Cotton fibre is used to make bath towels.
c) Umbrellas and raincoats are made from synthetic fibres
Answers
Answer:
a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.
b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.
c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.

After conducting the experiment and reviewing the data, a marine biologist states that sea
turtles nest from May to October and determines that August is the most critical month. This is
an example of which step in the Scientific Method?
A. analyze the results
B. conduct the experiment
C. form a conclusion
D. form a hypothesis
Answers
The scientific method includes the problem statement, previous knowledge, hypothesis and goals, methodology, results, and discusion/conclusion. The correct option is C. form a conclusion.
----------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on reproducibility and refutability.
When conducting an experiment, you need to consider,
Definition and problem statement. The question for which there is not an answer yet. A question the investigator wants to answer.
Theoretical framework. Antecedents from other investigations. Previous knowledge about the study object is always required for a better understanding.
The main goal of the study is basically what the investigator wants to find out.
Hypothesis formulation. The researcher makes a hypothesis to predict or make a conjecture -not verified and which requires corroboration- about what is going on or expected to happen.
Identification of the study groups, involved variables -independent, dependent, and control-.
Methodology description. Steps needed to get data.
Results. It includes data statistical analysis. This step involves testing the observations.
Discussion and Conclusion, through which the hypothesis might be rejected or accepted.
In the exposed example, the researcher has already collected field data, and made analysis.
Probably, the marine biologist noticed, while analyzing the results, that turtles lay eggs from May to October. But there might have been a biotic or abiotic factor threatening the survival of the eggs during august.
According to the analysis the researcher concluded that the nest season involves monthes between may and october, and august turns to be the most critical month for nesting.
The correct option is C.
