`|bara|=2, |barb|=3 and |2bara-barb|=5` then `|2bara+barb|` equals:

If absbara =3, absbarb = 4, and (bara-barb) = 5, " then " abs(bara+barb)=

If abs(bara+barb) = abs(bara-barb), " then " bara.barb =

Let bara and barb be vectors,satisfying |bara|=|barb|=5 and (bara,barb)=45^(@) . Find the area of the triangle having bara-2barb and 3bara+2barb as two of its sides.

If bara,barb,barc are three vectors such that absbara =1, absbarb = 2, absbarc =3 and bara+barb+barc = bar0 , then bara.barb+barb.barc+barc.bara =

If bara. barb = barb. barc = barc . bara = 0 then [bara barb barc] =

If absbara =2, absbarb =3, (bara,barb) = 120^(@), " then " bara.barb =

If bara, barb, barc are three vectors such that |bara|=|barc|=1, |barb|=4, |barb xx barc|=2 and 2barb=barc +lambda bara , then lambda=

Let bara be perpendicular to both barb,barc . If |bara|=2, |barb|=3, |barc|=4" and "(barb,barc)= (2pi)/(3) , compute |[bara barb barc]| .

If bare_(1) = (1,1,1), bare_(2) = (1,1,-1) and bara, barb " are two vectors such that " bare_(1)=2bara+barb and bare_(2)= bara+2barb, " then " (bara,barb) =
