Hmmm maybe salt I think I don’t even know
Answer:
2943 Pa
Explanation:
= Density of water =
g = Acceleration due to gravity =
V = Volume
A = Area
Mass of the blanket
Force on the ground applied due to its own weight
Pressure is given by
The pressure exerted by the water on the floor is 2943 Pa
Answer:
9000 J
Explanation:
Potential energy at the top = 10,000 J
Final potential energy = 1000 J
use the conservation of mechanical energy
Potential energy at top + kinetic energy at top = potential energy at a point + kinetic energy at that point.
10000 + 0 = 1000 + kinetic energy
kinetic energy = 10000 - 1000
kinetic energy = 9000 J
Thus, the kinetic energy is 9000 J.
Answer:
Resistivity Method
Explanation:
A disadvantage of some geophysical techniques based on magnetism is that their use in urban areas may be subject to distortion resulting from power lines and metals in the immediate vicinity. One method that can be used in such areas relies on soil moisture and the ground's resistance to electricity and is known as Resistivity.
It is usually carried out by injecting a small electrical current through the earth and measured a subtle sub-surface change in resistance over a given area.
The answer to this is +5m/s
