Answer:
Only circuit A will contain to lit bulbs
Answer:
Explanation:
Given
Mass of mother 
Mother is released with a speed of 
Assuming we need to find elastic Potential energy stored in Trampoline
Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring
I.e. Elastic Potential Energy=Kinetic Energy of mother

So 246.875 J of Energy is stored in the trampoline as he pull the ring
