Assume a three-phase, unity power actor load of 100 MVA with VLL of 69 kV is connected to a source through the below network. Convert the two impedances to per unit. Use a per unit three-phase 100 MVA base, a line-to-line 138 kV voltage base on the left side of the transformer and a line-to-line 69 kV voltage base on the right side.

probably not if net force is zero

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

not too sure thinking all accelerations are pointed down
