I think the correct answer from the choices listed above is option B. The formation of frost on a cold windowpane is an example of condensation. This process involves the phase change from the vapor phase to the liquid phase.
X=240 g NaCl salt dissolves in solution.
Example: If we add 68 g sugar and 272 g water to 160 g solution having concentration 20 %, find final concentration of this solution.
Solution:
Mass of solution is 160 g before addition sugar and water.
100 g solution includes 20 g sugar
160 g solution includes X g sugar
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
X=32 g sugar
Mass of solute after addition=32 + 68=100 g sugar
Mass of solution after addition=272 +68 + 160=500 g
500 g solution includes 100 g sugar
100 g solution includes X g sugar
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
X= 20 % is concentration of final solution.
Multiply velocity and time and you get 0.644 km, but remember that displacement has a direction and so does velocity, so because velocity is positive in the direction that the falcon is going you have a positive displacement.
