Answer:
KE = PE at half the table Height:
Explanation
AT ANY POINT IN THE BOOK'S FALL,
TOTAL E = PE +KE
THE TOTAL E IS CONSTANT
Before the book is pushed off, the total energy is potential
TOT E=PE =MGH
BEFORE THE BOOK HITS THE GROUND, THE TOTAL E IS KINETIC
TOT=KE = MVXV/2
WHEN KE = PE
KE+PE =<u> MGH (STARTING ENERGY SINCE E IS CONSERVED)</u>
<u>OR PE+ PE = MGH</u>
<u>OR MGH' + MGH' =MGH</u>
<u>OR 2H' =</u>H
H' (NEW HEIGHT) =H/2
Answer:
im pretty sure its groundwater just read this and see the answer
Explanation:
The ocean holds about 97 percent of the Earth's water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.
have a nice day buddy but I can't help you
The mathematical expression is given as:
(1)
where, 
= depression in freezing point
= molal freezing point.
Now, first calculate the 
Substitute the values in equation (1), we get
= 
or 
Now,
In 0.1 moles of water = 1 kg of butanol
So, 11.9 g of butanol = 
Convert gram into kilogram, (1 kg =1000 g)
= 
= 
Mass of water present in sample = 
= 
Hence, grams of water present in the sample =
