Answer:
Average velocity is 3.93 cm/s
Root mean square velocity is 4.79 cm/s
Velocity peak to peak is 6.28 cm/s
Explanation:
Speed of 2 particles = 5.3 cm/s
Speed of 4 particles = 1.4 cm/s
Speed of 6 particles = 7.14 cm/s
Speed of 8 particles = 1.52 cm/s
Speed of 2 particles = 7.68 cm/s
Average velocity is 3.93 cm/s
Root mean square velocity is 4.79 cm/s
Velocity peak to peak is 6.28 cm/s
Answer:
The population size decreases.
Explanation:

Answer: 0.5 m
Explanation:
Given
Mass of the person is 
Trampoline launches the person into the air up to height of 
Force experience by springs is 
Here, the work done on displacing the springs is equivalent to the Potential energy acquired by the person i.e.
![\Rightarrow F\cdot x=mgh\quad [\text{x=displacement of the trampoline}]\\\\\text{Insert the values}\\\\\Rightarrow x=\dfrac{50\times 9.8\times 2}{1960}\\\\\Rightarrow x=\dfrac{980}{1960}\\\\\Rightarrow x=0.5\ m](https://tex.z-dn.net/?f=%5CRightarrow%20F%5Ccdot%20x%3Dmgh%5Cquad%20%5B%5Ctext%7Bx%3Ddisplacement%20of%20the%20trampoline%7D%5D%5C%5C%5C%5C%5Ctext%7BInsert%20the%20values%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B50%5Ctimes%209.8%5Ctimes%202%7D%7B1960%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B980%7D%7B1960%7D%5C%5C%5C%5C%5CRightarrow%20x%3D0.5%5C%20m)
