    Thermal resistances adding formula

    Homework Statement Prove a rule for adding of Thermal resistances for: A)R1 and R2 in Series B)R1 and R2 in Parallel Homework Equations The Attempt at a Solution According to the book the result should be : A) R = R1 + R2 B) 1/R = 1/R1 + 1/R2 So i thought we can get some ideas from the...

    Movement of 2 particles Described by vectors

    We have 2 particles A and B - velocity vectors: v(A)=(2; 0), v(B)=(0; 3). In time t=0 these particles were in r(A)=(-3; 0), r(B)=(0. -3) (both are also vectors) Determine a vector of the reciprocal position of A and B (means the position of one relative to the other). Compute time and length...
