how far away is all 9 planets from the sun
The mass is 8.5 kg
I hope that's help !
Answer:
Before you make a hypothesis, you have to clearly identify the question you are interested in studying. A hypothesis is a statement, not a question. Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen
Explanation:
Before you make a hypothesis, you need to do preliminary research to understand the subject and define the problem. Collect and analyze relevant data and then based on your observations, you can create an educated guess or hypothesis to be tested.
Before you make a hypothesis, there are several important steps you should undertake. Firstly, you need to do some preliminary research. This research can involve reading books, scholarly articles, or trustworthy digital resources about the subject of interest. It is key to understand the subject well before developing a hypothesis. Secondly, you need to clearly define the problem or question you are interested in answering.
Next, make observations and gather data related to the problem. This is often called data collection and may involve conducting surveys, experiments, or fieldwork. After collecting and analyzing all the relevant data, you can formulate a hypothesis. A hypothesis is an educated guess about how things work or a tentative explanation that you will test in your experiment.

- Decreasing one of the masses to 1/2 of its original value
- Increasing the distance by a factor of
Explanation:
There are no options provided, however we can still answer the question.
In fact, the magnitude of the gravitational force between two objects is given by the equation:
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
We notice that:
Therefore, in order to reduce the gravitational attraction by one half, we can do one of the following changes:
- Decreasing one of the masses to 1/2 of its original value: for example, if , the gravitational force becomes
- Increasing the distance by a factor of : in fact, if , the gravitational force becomes

Answer:
Ep=0.66J
Explanation:
We have to use the formula for potential energy
where g is the gravity constant, h is the heigth an M is the mass. By replacing and taking into account the appropriate units (kg and m) we have
100g=0.1kg
68cm=0.68m
I hope this is useful for you
