Answer: <em>Newton's first law</em>
Explanation: <em>The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>

I’m not 100%sure but I think it would be indirect
Answer:
190 mL of water
Explanation:
5% solution means that 5 g of substance in 100 g of solution.
So, if we have 5 g of substance, and it has to be 100 g solution, than we need 100-5 = 95 g water.
100 g solution --- 5 g soda--- 95 g water
200g solution --- 10 g soda ---190 g water
For 200 g of 5% solution, we will need 10 g of soda and 200-10= 190 g of water.
Density of water = 1 g/mL
190 g * 1ml/g = 190 ml water
