Answer:
E.) Circuit Breaker is the correct answer.
Explanation:
Circuit Breaker is an automated electrical device that is designed to control and stop the excessive current flowing if the crosses a particular level and it protects the electrical circuit from the damage that can be caused due to overload of current that is the reason Circuit Breaker is called protective device.
There are different types of circuit breakers such as oil circuit breaker, vacuum circuit breaker, outdoor circuit breaker, Spring operated circuit breaker, Hydraulic circuit breaker and Medium-voltage circuit breaker, etc.
The acceleration of the box is 6 m/s²; option A.
<h3>What is the acceleration of the box?</h3>
The acceleration of the box is determined as follows:
Frictional force = 660 * 0.15 = 99 N
Net force = 500 - 99 = 401 N
- Force = mass * acceleration
Mass of the box = 660/9.8 = 67.3 kg
Acceleration = net force/mass
Acceleration = 401/67.3
Acceleration = 6 m/s²
In conclusion, the acceleration of the box is determined from the net force and the mass of the box.
