There are multiple reasons for this. First of all, water is available in almost every place on the Earth. It doesn't pollute the air, doesn't cause health use and is easily handle.
Other factor is the fact that water has a really high specific heat. This means that water, and more specifically steam, can aborb and transport more energy. A lower heat capacity would imply the need to boil more of the liquid to obtain the same amount of energy. This combine with the fact that water expands at a large rate when boiling, combine with everything mentioned previously, and you get a liquid with all the characteristics that a efficient turbine requires to work.
Answer:
Neglecting gravity, air resistance, etc
a)10m/s.
b)The stone is 5m above ground level after 0.50s.
Acceleration due to gravity on the surface of the moon=
Velocity/Time
distance/time/1.4
1.6/1.4^2
Approx 0.82m/s^2
Density = Mass / Volume
Density of stone = 100 / 10 = 10 g/mL
If the density is higher than water, then the object will sink. If the density of the object is lower than water, then the object will float.
Since the density of the rock is 10g/mL and the density of the water is 1g/mL, the stone will sink.
Explanation:
If Team A is on the left, B is on the right
if the force is constant, it means that the effort applied is equal.
So Team B is pulling 5000N to the right.
Answer:
Let d be the density of the water (1000 kg / m^3 eq to 1 gm / cm^3)
P = d g h for the pressure due to a column at the bottom of the column.
P = 1000 kg / m^3 * 10 m/s^2 * 10 m = 10^5 kg / m * s^2 = 10^5 N/m
