William Heathcote Solutions for Chapter: Interaction, Exercise 9: Summative assessment

A student wants to investigate the link between thunder and lightning. They design an experiment with a Van de Graaff generator. They plan to measure the loudness of the sound of the spark and compare it with the distance that the spark travels.

Write a method for this experiment including any measurements that should be taken.

The table below shows data for an experiment with a Van de Graaff generator. The Van de Graaff generator was charged and a spark crossed from its dome across to another smaller dome which was earthed. The student changed the distance between the two domes and measured the number of sparks that occurred in a minute.

Identify one limitation of this experiment and suggest how it might be improved.

The taller a building is, the greater the risk of a lightning strike. What solutions to this problem are there$?$

Carrying an umbrella in a thunderstorm is dangerous, particularly on flat open spaces. Write a paragraph to explain the dangers of this using scientific language in a way that a non-scientific could understand.

The following text comes from a paper by Kuldip Acharya and Dibyendu Goshal entitled $"$Flower inspired thunder protecting umbrella$"$. It was published on page $136$ of the journal $"$Proceedings of the International Conference on Simulation and Modelling Methodologies, Technologies and applications$"$ on $1$ January $2016$. 

The person study has dealt with an innovative idea regarding thunder protecting umbrella. The proposed umbrella can be folded and unfolded smoothly, and an animation algorithm is made to mimic the blooming of flower petals. The proposed umbrella is capable of protecting the user from any thunderstorm or lightning of any magnitude by providing a shielded conducting chord from the apex of the umbrella to the conducting spikes fitted at the bottom most layer of the shoe. The use of such an umbrella may be expected to provide a sound protection of the user to move within frequent thunder fall and lightning. The function of the proposed umbrella has been shown through computer animation. The movement of the user is easy in the presence of long flexible thin cable with appropriate connector jacks. The proposed design if manufactured at an industrial level may find some commercial utility also.

Give a reference for this paper that would be suitable for a bibliography.

The text states that the function of the umbrella $"$has been shown through computer animation$"$ explain why it might be that the umbrella has not been tested in real life, comment on the ethics of testing this umbrella with people.
