Ecosystem is an example of system.
Explanation
The best example of a system is the ecosystem.
The energy flow in the ecosystem starts from the sun which is the primary source of producing energy.
The sun provides energy to the plants and which will transfer energy to the animals or humans consuming them.
The energy is further transferred between the organisms by consumption of other organisms.
Even the decayed organisms are converted to fuel energy and the waste or unused energy is released as heat in the atmosphere.
Thus in the ecosystem, the law of conservation of energy is maintained as the energy transferred by the Sun to other organisms can be again converted to fossil energy once they have decayed.
The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.
<h3>What is electric file strength?</h3>
The electric field strength is defined as the ratio of electric force and charge.
The electric field strength is found as;

Hence, the electric field strength will be 0.6252 V/m.

Explanation:
Below is an attachment containing the solution.
I believe the answer would be , it may change from one element to another. I’m saying this because during nuclear transmutation is when a subatomic particle fired at the nucleus of an atom changes into a heavier element , to break the nucleus apart into two nuclei and energy.
