When does a scientist create the conclusion?

Physics
1 answer:
Gre4nikov [31]4 years ago
5 0


The best answer is d - while comparing the data with the hypothesis. The scientific method defines the correct steps as:

1. observation - use of the five senses to learn about something.

2. Question - where you raise questions based on your observation.

3. Hypothesis - a prediction or guess of what the answer to the question is.

4. Method - point where you test the hypothesis by carrying out an experiment.

5. Results / data - this is what happened after each step of the experiment.

6. Conclusion - where the results of the experiment are discussed and it  is summarized if the prediction was true or not, based on data from the results.

ladessa [460]

For this case we have, by definition, that:

Resistance is a component that is responsible for limiting the amount of current that can pass through a circuit, converting excess heat.

Consume energy.

Option A represents a swicth, option B represents a luminaire and option D represents a voltage source.

So, the correct option is C,

If a 15kg mass weighs 372 N on Jupiter, what is Jupiter's gravitational acceleration?
Dimas [21]

Answer:

Jupiter's gravitational acceleration is 24.8 m/s^2

Explanation:

Recall that the weight under the influence of a gravitational acceleration G is defined as:

Weight = m * G

Then, in our case we have

372 N = 15 kg * G

G = 372/15  m/s^2

G = 24.8 m/s^2

When a resistor is connected to a 12 volt source, it draws a 185 mA current. what's the resistance? (I said 65 ohms). the same r
lyudmila [28]

Resistance-1 = (voltage-1) / (current-1) =

                       (12 V)  /  (0.185 A)  =  64.9 ohms .

Resistance-2 = (voltage-2) / (current-2) =
 
                           (90 V )  /  (1.25 A)  =  72 ohms .

The resistance changed between situation-1 and situation-2 .
How did that happen ?

Power = (voltage) x (current)

Power-1 = (12)  x  (0.185)  =  2.22 watts

Power-2 = (90)  x  (1.25)  =  112.5 watts

The poor resistor dissipated 51 times as much power during
the second trial.  It got all heated up, and its resistance went
through the roof.

Carbon resistors behave nicely and reliably, until you try to
toast bread or light up your bedroom with them.
