Answer:
4800
Explanation:
You have to multiply the 1200 kg and the 2 m/s2. Then multiply the other 2 by the 2400 because it was the answer to the first part now after you multiply your answer is 4800.

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:
The manner in which the Earth's movement affect how the Sun is seen is;
The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky
Explanation:
The Earth's movement affect the way the Sun is seen
The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky
However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise rotation of the Earth about its axis
Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West
