Answer:
Total time = 20 hours
Explanation:
Half life is the amount of time it takes for a substance to decay tohalf of it's original amount.
Half life = 5 hours.
We have to obtain the number of half lives to get the time required.
1st half life = 1/2
2nd half life = 1/4
3rd half life = 1/8
4th half life = 1/16
So ffour half lives.
Total time = number of half lives * Time of half life
Total time = 4 * 5
Total time = 20 hours
Boyle's law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 4l , the pressure is 720 kpa (kilopascals). What is the pressure when the volume is 10l ?
<span>Using a calculator, we find that Usain Bolt's average speed over the 100 meter race was about 23.2 miles per hour. Note that some of the numbers in this calculation, namely 100, 3600, and 5280 are exact while 3.28 and 9.63 are only approximate. Since the approximate numbers only have 3 significant digits we only report three digits in the final answer.
