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.

<h3>
Answer:</h3>
83.33 seconds.
<h3>
Explanation:</h3>
<u>We are given;</u>
- Take off velocity as 300 km/hr
- Acceleration as 1 m/s²
We are required to calculate the take off time of the airplane.
<h3>Step 1: Convert velocity from km/hr to m/s </h3>
We are going to use the conversion factor.
The conversion factor is 3.6 km/hr per m/s
Therefore;
Velocity = 300 km/hr ÷ 3.6 km/hr per m/s
= 83.33 m/s
<h3>Step 2: Calculate the take off time</h3>
We know that;
v = u + at
where, u is the initial velocity, v the final velocity, a the acceleration and t is time.
But, initial velocity is Zero
Therefore;
83.33 m/s = 1 m/s² × t
Thus;
time = 83.33 m/s ÷ 1 m/s²
= 83.33 seconds
Therefore, the take off time is 83.33 seconds.
<span>Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton also stated that all compounds were composed of combinations of these atoms in defined ratios. He postulated that chemical reactions resulted in the rearrangement of the reacting atom.
