• ray creates an energy transfer diagram for a hair dryer. however, the diagram contains an error that could be corrected in several different ways.an illustration of a very wide arrow with a hair dryer at the tail labeled electrical energy 750 j. the arrow breaks into a 3 arrows a medium arrow going straight labeled kinetic energy 125 j and a much larger arrow curling away labeled thermal energy 550 j and the smallest curling away labeled sound energy 150 j.which of these changes would make the diagram error-free? check all that apply.reducing the amount of thermal energy to 475 jincreasing the amount of electrical energy to 825 jincreasing the amount of sound energy to 225 jreducing the amount of kinetic energy to 50 jreducing the amount of electrical energy to 675 j
  
• read the excerpt from thoughts and sentiments. it is therefore manifest, that something else ought yet to be done; and what is required, is evidently the incumbent duty of all men of enlightened understanding, and of every man that has any claim or affinity to the name of christian, that the base treatment which the african slaves undergo, ought to be abolished; and it is moreover evident, that the whole, or any part of that iniquitous traffic of slavery, can no where, or in any degree, be admitted, but among those who must eventually resign their own claim to any degree of sensibility and humanity, for that of barbarians. how does cugoano approach the topic of slavery in this excerpt? by praising the many good christians who are slaveholders by claiming that enslaved people will be freed when they become christians by describing people who need to be enlightened by accusing supporters of slavery of being ignorant and immoral
