c) By work energy theorem
d) we calculate net work through the law of conservation
Answer:
The plane will be located directly above the bomb because they both have the same horizontal speed.
Answer:
Option B
Wire each room in parallel with the next.
Explanation:
By having parallel circuit, it creates more than one path for energy source. That means that even if one route has been closed by one neighbour, the energy source can get another path. One advantage of parallel connection is that even if one load goes out, the rest of the bulbs within the circuit are not affected. For parallel circuit, voltage remains constant every time a new load is added or removed since each load has its own path to the energy source and will receive full voltage. Therefore, the electrician should wire each room in parallel with the next.
