(a) State the principle of homogeneity of dimensions.
(b) A student writes the relation τ+W=0, where τ is torque and W is work done. Using dimensional arguments, explain whether this equality is physically meaningful.
(c) Give one more pair of physical quantities that appear similar in everyday language but cannot be algebraically added because of dimensional mismatch. Justify your answer.
