4) Aos poucos, as pessoas estão aderindo às lâmpadas de LED que são mais eficientes, pois proporcionam a mesma energia luminosa de outras lâmpadas com menor consumo de
energia elétrica, ou seja, são mais econômicas. Sabendo disso, considere uma residência que
apresenta 8 lâmpadas fluorescentes compactas de 11 W que ficam acesas 5 horas por dia.
a) Qual o consumo de energia elétrica, em kWh, apresentado por essas lâmpadas em 1
mês (30 dias)?
b) Se cada uma das lâmpadas for trocada por uma lâmpada de LED de 7 W que
proporciona a mesma iluminação, qual será o novo consumo de energia elétrica, em
kWh, apresentado por essas lâmpadas em 1 mês (30 dias)?
c) Qual a quantidade de energia economizada em 1 mês (30 dias) com a troca das
lâmpadas?
d) Em um local onde o kWh custa R$ 0,50, qual o valor economizado anualmente na conta
de energia elétrica?

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
