Final answer:
To calculate the amount of micrograms lost per second, we divide the number of micrograms lost by the number of seconds in a week.
Step-by-step explanation:
To calculate the amount of micrograms lost per second, we first need to convert the 1.6 kg to micrograms. There are 1,000,000 micrograms in 1 gram, and 1,000 grams in 1 kg. So, 1.6 kg is equal to 1,600,000 micrograms. Next, we need to determine the time in seconds. Since the person lost 1.6 kg in a week, which is equal to 7 days, there are 604,800 seconds in a week. Finally, we can divide the number of micrograms lost (1,600,000) by the number of seconds in a week (604,800) to find the amount lost per second. The calculation is: 1,600,000 micrograms / 604,800 seconds = 2.64 micrograms/second. Therefore, the answer is approximately 2.64 µg/s. None of the options provided match the calculated result, so none of the given options are correct.
