no
its kinematics
the acceleration due to gravity and the initial vertical velocity are the only thing that affects vertical distance
No, the distance which it falls vertically does not affect by its horizontal velocity.
Downward acceleration of a projectile is same as downward acceleration of a free falling body due to constant gravity. Horizontal velocity ([tex]V_h[/tex]) does not affect vertical velocity ([tex]V_v[/tex]). Gravity affects vertical velocity ([tex]V_v[/tex]).The horizontal velocity of a projectile is constant. There is a vertical acceleration caused by gravity; its value is 9.8 m/s², down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.Learn more:

If the reaction occurs between Fe2S3(s) and H+ (aq) and the equation is properly balanced with the smallest
whole-number coefficients, what is the sum of the coefficients for all reactants and products?
Fe2S3(s) + H+ (aq)
The sum of the coefficients for all reactants and products is: 12.
Here, we first need to balance the equation of the reaction between Fe2S3(s) and H+.
The chemical equation yields H2S and Fe3+ as follows;Fe2S3(s) + H+ (aq) ------> H2S + Fe3+(aq)Balancing the equation consequently yields;Fe2S3(s) + 6H+ (aq) ------> 3H2S + 2Fe3+(aq)The sum of the coefficients for all reactants and products is therefore;
Sum = 1 + 6 + 3 + 2.
Sum of coefficients = 12

how many millilters of a 6.00 M sulfuric acid solution are reqired if you need 0.750 moles of H2SO4 for a reaction
125 milliliters of a 6.00 M sulfuric acid solution are required if 0.750 moles of H2SO4 are needed for a reaction.
HOW TO CALCULATE VOLUME:
The volume of a solution can be calculated by dividing the number of moles of that solution by its molar concentration. That is:Volume = no. of moles ÷ molarityAccording to this question, the molarity is given as 6.00 M sulfuric acid solution and the no. of moles is 0.75 moles. The volume is calculated thus:Volume = 0.75mol ÷ 6MVolume = 0.125LVolume of sulfuric acid in milliliters = 0.125 × 1000 = 125mLTherefore, 125 milliliters of a 6.00 M sulfuric acid solution are required if 0.750 moles of H2SO4 are needed for a reaction.Learn more at: https://brainly.com/question/2817451?referrer=searchResults

David drops a golf ball and a bowling ball at the same time. He then drops a tennis ball and a volleyball. He notices that each pair hit the ground at the same time. Then David picks up a marble and a baseball. If he drops them both at the same time, what can David predict will happen
Answer:
if he drops them some where there is no air they will both land at the same time as they have no air resistance and gravity pulls every item equally but if they just do it of a building in the middle of the street then the baseball would hit first as it has a larger mass

In this experiment, between 1.900-2.100 g of a mixture containing the reactants zinc sulfate and sodium phosphate was added to acidified water to undergo a double displacement (precipitation) reaction. This mixture had an unknown percent composition of reactants. To make matters more complicated, the unknown mixture did NOT contain stoichiometric quantities of the reactants.
1. (1 point) Write a molecular equation for the reaction of aqueous zinc sulfate and aqueous sodium phosphate.
An excess of sodium carbonate, Na, CO3, in solution is added to a solution containing 17.87 g CaCl2. After performing the
experiment, 13.19 g of calcium carbonate, CaCO3, is produced. Calculate the percent yield of this reaction.
Answer:
Approximately [tex]81.84\%[/tex].
Explanation:
Balanced equation for this reaction:
[tex]{\rm Na_{2}CO_{3}}\, (aq) + {\rm CaCl_{2}} \, (aq) \to 2\; {\rm NaCl}\, (aq) + {\rm CaCO_{3}}\, (s)[/tex].
Look up the relative atomic mass of elements in the limiting reactant, [tex]\rm CaCl_{2}[/tex], as well as those in the product of interest, [tex]\rm CaCO_{3}[/tex]:
[tex]\rm Ca[/tex]: [tex]40.078[/tex].[tex]\rm Cl[/tex]: [tex]35.45[/tex].[tex]\rm C[/tex]: [tex]12.011[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].Calculate the formula mass for both the limiting reactant and the product of interest:
[tex]\begin{aligned}& M({\rm CaCl_{2}}) \\ &= (40.078 + 2 \times 35.45)\; {\rm g \cdot mol^{-1}} \\ &= 110.978\; \rm g \cdot mol^{-1}\end{aligned}[/tex].
[tex]\begin{aligned}& M({\rm CaCO_{3}}) \\ &= (40.078 + 12.011 + 3 \times 15.999)\; {\rm g \cdot mol^{-1}} \\ &= 100.086\; \rm g \cdot mol^{-1}\end{aligned}[/tex].
Calculate the quantity of the limiting reactant ([tex]\rm CaCl_{2}[/tex]) available to this reaction:
[tex]\begin{aligned}n({\rm CaCl_{2}) &= \frac{m({\rm {CaCl_{2}})}}{M({\rm CaCl_{2}})} \\ &= \frac{17.87\; \rm g}{110.978\; \rm g \cdot mol^{-1}} \\ &\approx 0.161023\; \rm mol \end{aligned}[/tex].
Refer to the balanced equation for this reaction. The coefficients of the limiting reactant ([tex]\rm CaCl_{2}[/tex]) and the product ([tex]{\rm CaCO_{3}}[/tex]) are both [tex]1[/tex]. Thus:
[tex]\displaystyle \frac{n({\rm CaCO_{3}})}{n({\rm CaCl_{2}})} = 1[/tex].
In other words, for every [tex]1\; \rm mol[/tex] of [tex]\rm CaCl_{2}[/tex] formula units that are consumed, [tex]1\; \rm mol\![/tex] of [tex]\rm CaCO_{3}[/tex] formula units would (in theory) be produced. Thus, calculate the theoretical yield of [tex]\rm CaCO_{3}\![/tex] in this experiment:
[tex]\begin{aligned} & n(\text{${\rm CaCO_{3}}$, theoretical}) \\ =\; & n({\rm CaCl_{2}}) \cdot \frac{n({\rm CaCO_{3}})}{n({\rm CaCl_{2}})} \\ \approx \; & 0.161023\; {\rm mol} \times 1 \\ =\; & 0.161023\; \rm mol\end{aligned}[/tex].
Calculate the theoretical yield of this experiment in terms of the mass of [tex]\rm CaCO_{3}[/tex] expected to be produced:
[tex]\begin{aligned} & m(\text{${\rm CaCO_{3}}$, theoretical}) \\ = \; & n(\text{${\rm CaCO_{3}}$, theoretical}) \cdot M(({\rm CaCO_{3}}) \\ \approx \; & 0.161023\; {\rm mol} \times 100.086\; {\rm g \cdot mol^{-1}} \\ \approx \; & 16.1161\; \rm g \end{aligned}[/tex].
Given that the actual yield in this question (in terms of the mass of [tex]\rm CaCO_{3}[/tex]) is [tex]13.19\; \rm g[/tex], calculate the percentage yield of this experiment:
[tex]\begin{aligned} & \text{percentage yield} \\ =\; & \frac{\text{actual yield}}{\text{theoretical yield}} \times 100\% \\ \approx \; & \frac{13.19\; {\rm g}}{16.1161\; {\rm g}} \times 100\% \\ \approx \; & 81.84\%\end{aligned}[/tex].
