I believe the correct answer from the choices listed above is the second option It is during sublimation that molecules directly move from state to state involving a vibration of particles in a fixed position to a state involving random movement of high speed particles. It <span> is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. </span>
Answer:
Both have the same amount. C.
Explanation:
Answer:
i. The pressure of due to the water, <em>P</em>, is given according to the following equation;
P = ρ·g·h
Where;
ρ = The density of the water (a constant) = 997 kg/m³
g = The acceleration due to gravity = 9.81 m/s²
h = The height of the water (minimum h = h₁, maximum h = h₂)
The pressure is directly proportional to the water height, and we have;
The pressure, <em>P</em>, will be maximum when the water height, <em>h</em>, is maximum or h = h₂, which is the level DC
ii. The thrust = The force acting on the body = Pressure × Area
The maximum areas exposed to the water are on side AB and DC
However, the pressure at level DC, which is the location of the maximum pressure, is larger than the pressure at level AB, therefore, the maximum thrust will be at the level DC
