Answer:
Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to dissociate icons in salts and bonds to each other polar substances such as alcohols and acids thus dissolving them.
Answer:
The correct answer is - newspaper articles and farmers' harvest yield records.
Explanation:
Paleoclimatologists are the people that study the ancient climate before the availability of the instrumental records or the data and therefore depend on the coral reefs or the rocks and also compare the current climate how dramatically different climate states occur in few decades.
Dina should examine newspaper articles to find out what type of climate was before and now in her hometown and she should also check records of farmer's harvest yield to get what type of weather and climate was there.
Solve the
potential energy at point B
PE = mgh
Where m is
the mass
G is the
acceleration due to gravity 9.8 m/s2
H is the height
PE = ( 1.5
kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Solve the
velocity using the
KE = 0.5mv^2
Where ke is
the kinetic energy
M is the
mass
V is the
velocity
Since all
energy is converted to KE
So KE = PE
7.35 = 0.53(1.5)
v^2
V = 3.13 m/s
