1000 g of feathers is the least dense
Religion and science are fundamentally incompatible. They disagree profoundly on how we obtain knowledge of the world. Science is based observation and reasoning from observation. Religion assumes that human beings can access a deeper level of information that is not available by either observation or reason.
Answer:
A
Explanation:
Hot air is less dense therefore it rises. Cold air is more closely packed therefore it is more dense. Less dense things rise while more dense things sink.
Hydrazine is a mixed chemical...look up what is in Hydrazine. Then find the chemicals in it. 13.00g of hydrazine can react to anything....water, gas, etc. but it might not be visible.
1. Make an observation
: My toaster doesn't toast my bread
2. Ask a question
: Why doesn't my toaster work?
3. Form a hypothesis
: My coffeemaker works when plugged into the outlet
4. Make a prediction
: If something is wrong with the outlet, then my coffeemaker also won't work when plugged into it
5. Conduct an experiment
: I plug my coffeemaker into the outlet
6. Analyze the results
: There is something wrong with the electrical outlet
Explanation:
The solution to the problem is as shown above.
- A scientific method follow a methodical way of critically carrying out an inquiry into an observation.
- Firstly, an observation is usually made with our senses. Here the researcher observes that the toaster does not toast his bread probably after a long wait.
- He then proceeds to ask why the toaster does not work.
- To investigate this, the forms a hypothesis. A hypothesis is a scientific guess. It is a tentative proposition about an investigation.
- The researcher then makes a prediction about the outlet that might be faulty.
- With this background, he goes on to carry out an experiment to substantiate his findings. This is seen when he plugs the coffeemaker into the outlet.
- From the analysis of result, he sees that that something is wrong with the outlet.
