1. Consider a fire hose with a 9.25 cm diameter. What is the fluid speed in the fire hose in meters per second if it is carrying 78 L of water per second? What is the flow rate, in cubic meters per second?2. The human circulation system has approximately 1*10^9 capillary vessels. Each vessel has a diameter of about 8 um. Assuming the cardiac output is 5L/min, determine the average speed, in centimeters per second, of blood flow through each capillary vessel. 3. An expensive vacuum system can achieve a pressure as low as 1.15*10^-7 Pa at 20 degrees celsius. How many atoms are there in a cubic centimeter at this pressure and temperature?
Dry ice and soap mixed makes dry ice and soap no chemistry goes on at all. Just physics. The soap gets bubbles blown by the CO2 and freezes. No jelly like material, no vanishing when you touch it. Don't believe all the BS you see in the movies. They're not written by scientists but by scriptwriters who know diddly about a lot of the 'science' they portray. If this is a serious question and you're really a 3rd year biochem major you need to spend more effort on your studies and less on believing the movies.
I would conquer the world. Plain and simple.
Mark 3:29 However whoever blasphemes against the holy spirit has no forgiveness forever,but is guilty of everlasting sin. I know you don't believe but I would be very careful if I were you.
Well.I would probably creep into the school at night time with my phone (as long as my phone turned invisable too ^.^) and go to my lab teacher's classroom with my video recorder on to prove that he really does watch porn in between and after all classes! (like, seriously no joke) One time me and my friend, Abby, were walkin to class and we are usually the first ones in there because our locker is right next to the door and when i came in i heard sexual noises and i looked up to the smartboard and he was like going crazy x-ing out of stuff. True story, it actually happened, seriously swear, lol
