A. 11.%
B. 22.2%
C. 10%
D. 20%
Correct Answer:
Option C = 10%
Explanation
Mass of Solution = Mass of Solute + Mass of Solvent → 20g + 180g
: Mass of Solution = 200g
Mass Percent = Mass of Solute /Mass of Solution X 100
Mass percent = 20/200 X 100
Mass percent = 10%
![A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s. [g = 10ms-2]. Determine the potential energy of the body at the maximum height of its motion. A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s. [g = 10ms-2].
