Acceleration due to Gravity:
- The speed of the water ejected from the hole does not depend on the acceleration due to gravity because it only affects the downward force acting on the liquid within the tank.
- The force causing the water to be ejected from the hole is the pressure difference between the surface of the liquid in the tank and the hole.

Area of the Hole:
- The speed of the water ejected from the hole does not depend on the area of the hole.
- This is because the speed of the water is determined by the pressure difference between the surface of the liquid in the tank and the hole, not the size of the hole itself.

Density of the Liquid:
- The speed of the water ejected from the hole does not depend on the density of the liquid.
- The pressure difference that causes the water to be ejected is determined by the height of the liquid above the hole, not the density of the liquid.

Height of the Liquid from the Hole:
- The speed of the water ejected from the hole does depend on the height of the liquid above the hole.
- The greater the height of the liquid above the hole, the greater the pressure at the hole, resulting in a higher speed of the water being ejected.
