Answer:
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected
In order to get the magnitude of the electric field at the location of the test charge, you have to use the formula: E=Fe/q.
Given E as electric field strength; Fe as electric force = 0.751 N and q as charge = 5*10-5 C. Therefore,
E= 0.751 N / 5 * 10-5 CE=15020 N C-1 or V m-1 Electric field at the location.

Answer: Blackbody
Explanation:
what is black body radiation ?
An ideal body which can emit and absorb radiation of all frequencies is called a black body. The radiation emitted by such bodies is called black body radiation.
How is blackbody radiation produced?
Electromagnetic radiation is produced from all objects according to their temperature. An idealised object that consumes the electromagnetic energy that it comes into contact with is a black body. In a continuous continuum, which then emits thermal radiation according to its temperature.
