Answer:
4.D.all of them are correct
5. B.Making observation
Answer:
A. Theory
Explanation:
The scientific method consists of following six steps:
1. Observation 4. Prediction
2. Experiment 5. Hypothesis
3. Law 6. Theory
1. Observation:
Observations are taken carefully and systematically. In this way all possible information is gathered
about physical phenomenon.
2. Hypothesis:
Keeping these observations in mind scientist makes some postulates to explain the phenomenon. These postulates are called hypothesis.
3. Theory:
Scientist design a theory on the basis of hypothesis and gives an elaborated explanation about the phenomenon.
4. Prediction:
Sometimes a scientist presents a theory on the basis rational reasoning and predicts some phenomenon to take place under certain conditions.
5. Experiment:
The theory or prediction is tested by experiments. If the theoretical and experimental results agree with each other, the theory is accepted otherwise it is discarded.
6. Law:
A theory which is tested again and again and found to fit the facts and from which valid predictions are maybe made are known as ‘Law’.
So it is clear from the given explanation that the term, which best describes the phrase ""a description of what happens in nature" is:
<u>A. Theory</u>
Answer:
i) Angle of Reflection = Angle of Incident
ii) Total Angle = 2x Angle of reflection/incidence
iii) The incident ray, reflected ray and the point of incidence lie in the same plane

Answer:
the acceleration is 9200m/s^2
Explanation:
We are going to use newton's law formulas, according to newton:
We have the mass, and the force applied, so we can obtain the acceleration rearranging the formula:
substituting what we have:
In infrared satellite images, land appears black and clouds appear white. C
<h3>What are infrared satellite images?</h3>
Infrared satellite images are images produced as a result of electromagnetic radiations reflected or emitted from a target surface in the infrared position of the electromagnetic spectrum.
On infrared images, the clouds emit very bright white color because of the low temperature and the land appears to be black because of the hot temperature.
Therefore, in infrared satellite images, land appears black and clouds appear white. C
