Physics

A student gave a formula for the coefficient of thermal conductivity $$K = \frac { d } { A \left( \theta _ { 1 } - \theta _ { 2 } \right) t }$$ where $$d$$ is the thickness, $$A$$ is the area, $$\theta _ { 1 }$$ and $$\theta _ { 2 }$$ are the temperatures and $$t$$ is the time. The dimensional formula of the missing term is

Q4 Single Correct Medium
The resistance of a metal is given by $$R = V/I$$, where $$V$$ is potential difference and $$I$$ is the current. In a circuit, the potential difference across resistance is $$V = (8 \pm 0.5)V$$ and current in resistance, $$I = (4 \pm 0.2)\mathring{A}$$. What is the value of resistance with its percentage error?
  • A. $$(2 \pm5.6\%)$$
  • B. $$(2 \pm0.7\%)$$
  • C. $$(2 \pm35\%)$$
  • D. $$(2 \pm11.25\%)$$
