ANSWER D ONLY 8a Show how Pip can complete the circuit by adding less than 120 cm oftrack.b Show how Pip can complete the circuit by adding more than 270 cmof track.e Explain why, no matter how the circuit is completed, Pip must placean even number of additional curved plates.d Explain why, no matter how the circuit is completed, Pip must placean odd number of additional straight plates. Intermediate Problems714 Slot CarsPip is building model car racing tracks using a large supply of the twoof square plate shown. Ignoring the tabs and slots where platestypesare snapped together, both types measure 20 cm x 20 cm. In the firsttype, the track is a straight line joining the middles of opposite sides. Inthe second, the track is a quarter circle joining the middles of adjacentsides. Plates can be snapped together in any orientation, as long as thetrack is continuous.20 cm20 cm20 cmPip wants to complete the track shown below but, because there is lim-ited space, additional plates can only be put in the 4 x 4 grid indicatedby dotted lines.

In order to complete the circuit, the curved plate on the topmost right side of the circuit must be…

Do not solve the full qn My question is why is the vector VAot = 1.5 and VAon =-2.6 as shown in the solution. I understand VAot is = -3cos30=-1.5 and VAon = -3sin30 =-2.6 Why is it postive 1.5 instead of negative 1.5 or for VAon why isit negative 2.6 and not positive 2.6? Are you able to show in a vector diagram
Do not solve the full qn My question is why is the vector VAot = 1.5 and VAon =-2.6 as shown in the solution. I understand VAot is = -3cos30=-1.5 and VAon = -3sin30 =-2.6 Why is it postive 1.5 instead of negative 1.5 or for VAon why isit negative 2.6 and not positive 2.6? Why is Vb1t = -0.866 and not 0.866 and Vb1n = -0.5 and not 0.5. I dont get it how to visualise the vector direction. Please use a vector diagram with the angles to illustrate it.
