For horizontally-launched projectiles, which of the following describes acceleration in both directions with a = 0 and a = -9.8m/s^2 1. Acceleration is constant in both directions
2. Acceleration is -9.8m/s^2 in both directions
3. Acceleration is zero in both directions
4. Acceleration is equal in both directions

4 is the best option for it as there are some stuff in grade to ye

We know that the formula to mix chemical solutions is: C1V1 = C2V2

where C represents the concentration of the solute, and V represents volume in milliliters or ml.

In this case, we have:

0.06V1 = 0.15×350

Solving for 'V1' we have:

V1 = (0.15×350)/0.06 = 52.5/0.06 = 875

Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
