Four different types of light globes were tested for their efficiency. The results are in the table below. Globe numberHeat outputLight output
185%15%
290%10%
350%50%
430%70%

(a)Identify the energy source that was converted to produce light and heat from the globe?



(b)Define the term ‘efficiency’ in relation to this globe test.



(c)Which globe is the most energy efficient? Explain your answer using data from the table.





(d)Describe why is it desirable to have energy-efficient light globes?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Asubject in a clinical research trial experiences a serious, unanticipated adverse drug experience. how should the investigator proceed, with respect to the irb, after the discovery of the adverse event occurrence? a. do not report the adverse drug experience to the irb since it is a common adverse experience.b. report the adverse drug experience to the irb only if there are several other occurrences.c. report the adverse drug experience as part of the continuing review report.d. report the adverse drug experience in a timely manner, in keeping with the irb's policies and procedures, using the forms or the mechanism provided by the irb.
