Answer:
x is positive y is negative
Explanation:
because the ones from x are moving away from it and the ones from are moving towards it
Atoms, molecules, electrons, photons, protons etc.
By Boyle's law:
P₁V₁ = P₂V₂
70*8 = P<span>₂*4
</span>P<span>₂*4 = 70*8
</span>
P<span>₂ = 70*8/4 = 140
</span>
P<span>₂ = 140 kiloPascals.</span>
distance(d) = speed(s) × time (t)
= 22.3 × 8.5
= 189.55m
