Answer: True
Explanation:
The definition of minimum spanning tree(MST) says that the graph must be connected and undirected to be considered for MST. It has (V-1) edges where V is the number of vertices. The minimum spanning tree is implemented using Kruskal's algorithm whereby it starts by considering the minimum weighted edge and covers all the edges upto (V-1) edges. So for MST it has to be connected
Answer:
$2.40
Explanation:
the unit electricity bill is kilo watt hour.
The 60-watt light bulb has a 400 hour life expectency means it will consume
60×400/1000 = 24 KWh units of electricity. Let us suppose each unit of electricity costs is 10 cents.
Then 24×10 = 240 cents = $2.40
