Hypocenter (under the ground where earthquake actually begins), or epicenter(above hypocenter on the ground, useful to locate on the map)
friction and the density of the air.
Answer:
1. 80,000 Pa
2. 11.3 m/s
3. 12.5 m/s
Explanation:
<u>Question 1</u>
Pressure, 
Where h is the height that water is to reach, g is gravitational constant and
is the density, in this case, we assume
of pure water as 
Assuming 
P=8*10*1000=80000 Pa
<u>Question 2</u>
Pressure can also be found by the formula
where v is the velocity
Equating the new formula of pressure to the formula used in question 1 above

Notice that
is common hence

Making V the subject of the formula


In this case, h=8-1.6=6.4m and taking g as 10 m/s^{2}

Rounding off to 1 decimal place
v=11.3 m/s
<u>Question 3</u>
As already illustrated

Taking g as 9.8 and h now is 8m

v=12.52198067
Rounding off to 1 decimal place
v=12.5 m/s
Answer:
People can capture geothermal energy through: Geothermal power plants, which use heat from deep inside the Earth to generate steam to make electricity. Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings
When the weather is cold, the water or refrigerant heats up as it travels through the part of the loop that's buried underground. Once it gets back above ground, the warmed water or refrigerant transfers heat into the building. The water or refrigerant cools down after its heat is transferred.
