Absolute pressure at the bottom of the lake = pressure due to water height + Air pressure = Density of water*gravitational acceleration* height + 101.3 kPa
Therefore,
Absolute pressure = 1/1000(1*10^3*9.81*29.1) + 101.3 = 285.471+101.3 = 386.771 kPa
Answer:
Average speed = 26.67 km/h
Explanation:
It is given that,
The first half of the journey by a body is traveled with a speed of 40 km/h and the next half is covered with a speed of 20 km/h
We need to find the average speed of the whole journey. When two speeds are given, the average speed is given by :
So, the average speed of the body of the whole journey is 26.67 km/h.
Weathering is the breaking down of rocks............
Answer:
Nuclear fission of heavy elements produces exploitable energy because the specific binding energy (binding energy per mass) of intermediate-mass nuclei with atomic numbers and atomic masses.
Explanation:
have a great day!! :)
Density=mass÷volume
density=40.5÷15=2.7
