When storm clouds produce lightening and thunder, then, potential energy changes into kinectic energy.
The clouds become negatively charged,and the ground is positively charged during a storm. So there creates a potential difference between the charged clouds and the ground. And when this becomes huge so much that it over comes the electrical insulation cover of air, the electrons jump to the ground.i.e. the potential energy changes into kinetic energy.
HELLO THERE
THE ANSWER IS

HOPE THIS HELPS
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.
Answer:
Explanation:
We are given that
Current,I=
We have to find the maximum charge of the capacitor.
Charge on the capacitor,
....(1)
....(2)
Equation (2) divided by equation (1)
Hence, the maximum charge of the capacitor=
It would take 3.6 hours for a car to travel 200 km going 55 km/hr.
