Without counting wind resistance, They will both reach the ground at the same time. If we apply the concept of kinematics, such as the equation vf^2=vi^2 + 2ad. This equation doesn't count how big or how heavy the mass is, it only focuses on how fast where they in the start and how far are both of them from the ground. So if they both have the same distance and same initial veloctity, then they will reach the ground at the same time.
For example, Try dropping a pen and a paper(Vertically) at the same height, you'll see they'll reach the ground at the same time.
If you count wind resistance, the heavier ball will hit the ground faster, because the air molecules will resist the lighter ball compared to the heavier ball.
570 is the answer for your problem.
Well, if the bag is moving across the floor at a constant velocity. Then I would assume that the Fnet force is equal to 0, and thus the value of acceleration would also be equal to 0.
Answer:
True.
Explanation:
Adding a non - volatile solute to solvent, decreases the tendency for water molecules to evaporate into gas phase i.e these non - volatile solute particles obstruct or reduce the rate of evaporation. Few water molecules in the vapour.
Therefore, Adding a nonvolatile solute to a solution decreases the vapor pressure of the solution while
Vapor pressure is a measurement of the likelihood of the molecules of a pure solvent to change from the liquid to the vapor phase.
Using Raoult's Law:
Psol = Xsolv * P°solv
where:
Psol = the vapor pressure of the solvent above the solution,
Xsolv = the mole fraction of the solvent in the solution, and
P°solv = the vapor pressure of the pure solvent.
