<span>The rate of infusion is 2.1L/19h or 2100mL/19h (as 1L = 100 mL).
To convert 19 hours to minutes we multiply as follows:
19 hours = (19 hours) x (60 minutes/1 hour) = 1140 minutes
So the rate of infusion becomes:
2100mL /1140 min
In order to converted mL to drops (gtt) we multiply the rate of infusion with the drop factor to get the drip rate:
(2100mL/1140min) x (20 gtt/mL) = 36.8 gtt/min</span>
Y=15 x=60
•1/3 •1/3
y=5 x=45
Half-life is basically how long it takes for a radioactive molecule to get to 1/2 of its original mass.
so if sodium 24 mass was 5g and it's half life was 24years then:
after every 24years 1/2 of 5g would have decayed. so in 48years there will only be 2.5g left.
Answer:
Refer to explanation
Explanation:
Weather is the main cause behind most short term environmental changes
For example, a period of heavy rain may lead to a pond overflowing, and flooding the nearby shrubbery
Animals in the area would adapt to this by trying to keep away from the flooded area until it dries out, once the rain ends

That is what it would be balanced, hope this helped</span>
