A ground wire provides a conducting path to the earth which is separate and independent from the path of an electrical appliance. Also, a ground wire is an additional pathway for an electric current to safely return to the ground without imposing danger to anyone in the event that a short circuit might occur. This is particularly important for shock hazard since it forces the breaker to trip by supplying a path to the ground if ever a hot wire comes in contact with a metal case of the appliance.

A fuses and circuit breakers limit the current which can possibly flow in a circuit. The metal filament present in the fuse will melt and break the connection. On the other hand, the circuit breaker with its bimetallic strip's heating effect causes a bending and tripping of a spring-loaded switch.

A cyclist is traveling 10 m/s with an acceleration of 6 m/s2. How fast is the cyclist traveling at the end of 20 seconds
krok68 [10]

Answer:

<em>The cyclist is traveling at 130 m/s</em>

Explanation:

<u>Constant Acceleration Motion </u>

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

v_f=v_o+at

The cyclist initially travels at 10 /s and it's accelerating at a=6m/s^2. We need to know the new speed when t= 20 seconds have passed.

Apply the above equation:

v_f=10+6\cdot 20

v_f=10+120

v_f=130\ m/s

The cyclist is traveling at 130 m/s
