Answer:
Both balls hit the ground simultaneously
Explanation:
Let´s call b₁ ( the ball dropped ) the equation for a free fall movement is, tacking as the origin of coordinates the level from which it was dropped
V = g*t ( since V₀ initial velocity is 0 )
In the case of projectile movement the equation for Vx and Vy (these speeds are independent)
are:
Vx = V₀x (constant) and Vy = Voy + g*t
Vy = V₀ * sin 0⁰ + g*t Vy = 0 + g*t
As we can see V is the same in both cases then the balls hit the ground simultaneously
Answer:
No, its not possible for water to dissolve almost anything in the universe.
Explanation:
Solubility of a solute defines the ability of that solute to dissolve in a given solvent. It is defined as the maximum amount of solute dissolved in a solvent at equilibrium. The solution which results from dissolving this maximum amount is called a saturated solution, and one it has been reached, no more solute can be dissolved in it.
Different substances in the universe have diffferent solubilities in water, some very high (soluble) (eg. sugar and salt) and some very low (insoluble) (eg plastics). The substances that are able to form bonds with water (Hydrogen or Ionic) are more soluble than those who are not able to do so.
I think it’s air pressure
