They provided the intensity in decibels for the problem, but they are unsure by what factor to increase it (I) to make the sound loud enough for the elderly person to hear.
Neglect f entirely.
The following equation must be used to convert decibels (dB) to I:
I=(10^(dB/10))*10^-12
Divide the elder person's dB by the younger person's dB after doing this for each dB.
After putting values and solving
we get,
1.8372093023.
So, the final answer is 1.8372093023.

Answer:
The final energy of the system is 168 J
Explanation:
Heat energy released to the surroundings, 
Work done, W = 222 J
The initial internal energy, 
The change in internal energy is given by the formula, 
The final energy of the system is 168 J
Answer:
yes
Explanation:
It's because as total energy remains constant, kinetic energy decreases potential energy increases. as an object moves the potential energy gradually gets decreased while kinetic energy increases so as to maintain energy constant.
