For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
Answer:
The straight line
Explanation:
All the other stuff is sound waves
The last one. Opposites attract while similar ones repulse each other so all forces are pushing them apart
You said 0.5 · m · v² = m · g · h
Divide each side by 'm' : 0.5 · v² = g · h
Multiply each side by 2 : v² = 2 · g · h
Square root each side : v = √(2 · g · h)
You said that g = 9.8 m/s² and h = 875 units
So v = √(9.8 m/s² · 875 units)
v = √(8,575 m·unit/s²)
v = 92.6 / s² · √(m · unit)
A hydraulic arrangement consists of a water- filled U-tube that is wider on one end than on the other. Pistons are fitted in both ends.
