Create a spanning tree using the breadth-first search algorithm. Start at A (ie 0). What is the maximum number of edges needed to connect any other vertex to vertex 'A'? A) 1

B) 2

C) 3

D) 4

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
