Answer:
100.008 km/h
Explanation:
multiply the speed value by 3.6
The minimum size copper equipment grounding conductor that is required is ; #4 copper
<h3>Equipment grounding conductor </h3>
An Equipment grounding conductor is a conductive part of ground fault current path which connects the non-conducting metallic parts of the euipment together and also connects the system grounded conductor.
For a copper euipment grounding conductor required to serve a control center connected to a 300 amp over current device the minimum size of copper is #4 copper
Hence we can conclude that The minimum size copper equipment grounding conductor that is required is ; #4 copper.

Answer:
Explanation:
Heat energy reaches other planets and satellites of the solar system through the process called radiation.
In this process , the heat energy travels in the form of electromagnetic waves which do not require any material medium . It is so because it is a non mechanical wave . Hence heat energy reaches earth or moon even when there is no material medium between sun and the moon . Other mode of transfer of heat requires medium like solid or liquid or gas to travel from one point to another .
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
Answer:
<em>1. If the switch is closed, the total resistance of the circuit remains the same</em>
<em>2. The brightness of the bulb A when the switch is closed remains the same.</em>
<em></em>
Explanation:
An ideal battery has no internal resistance, and hence, maintains a constant value of voltage without diminishing. The total resistance of the circuit will remain constant since this is an inherent unchanging property of a conducting circuit provided there is no change to its configurations. The brightness of the bulb A will remain unchanged since we are considering an ideal battery. In practice, ideal batteries don't exist, reason why battery powered light bulbs gradually dim with time as the internal resistance increases, till it eventually dies.
