7. If the battery voltage is D V, and the resistances are R1=C/50 2, R2-B/5 22 and R3=D/2 22. www R₁ R₂ (a) What is the total resistance? (b) Find the current? (c) Calculate the voltage drop in each resistor? (d) Calculate the total power dissipated by the circuit?

Consider three vectors: What is the result of 2A. (B-3C)? What is the result of A A+B B + C. C? . A.A+B B+C . C = || A = (9.71) î+ (1.12) Ĵ B = (7.28) + (5.54); C = (-2.95) + (-14.7);

Vector v = <1,1,0> and vector w = <-1,-1,sqrt2>. What is the angle between v and w in degrees?

Need some assistance with this.  l = 1.95 mm.    w= 1.89 mm.    h= 5.82 m.  Coordinates for Point A is A(2,2,2)m Coordinates for Point D is D(2.25,2.5,0)m Force F acts along  EA, (Magnitude is 55N) Force P acTS along AD    4. What is BC as position vector rBC.  ( rBCx, rBCy, rBCz ) 5. What is BC as unit vector uBC. (uBCx, uBCy, uBCz ) 6. What is the moment that F creates around B ? (MB) 7. What is the magnitude of the moment that F creates around axis BC. ( |MBC|  )
