Answer: What's your answer?
Explanation:
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.
Answer:
Option B , Binding Energy
Explanation:
The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.
When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.
Hence, Option B is correct.
The correct answer to this open question is the following.
Although you forgot to attach the options for this question we can say the following.
A cruise ship makes its way from one island to another. the ship is in motion compared with which reference point?
The correct answer is "a lighthouse on a nearby island."
In this case, that is the function of the lighthouse. To be the point of reference or the guiding element that the captain of the ship is going to use to keep the ship's trajectory correct.
Although there are uncontrollable external elements such as heavy storms, fog, or bad weather, the captain of the ship is going to be guided by the lighthouse.
