Solve the Problem $\varepsilon$ Of a Particular Thermoplastic Can Be Modeled Approximately by the Can

Multiple Choice

Solve the problem.
-The elasticity $\varepsilon$ of a particular thermoplastic can be modeled approximately by the relation $\varepsilon = \frac { 2.5 \times 10 ^ { 5 } } { \mathrm {~T} ^ { 2.3 } }$ , where $\mathrm { T }$ is the Kelvin temperature. If the thermometer used to measure $\mathrm { T }$ is accurate to $1 \%$ , and if the measured temperature is $478 \mathrm {~K}$ , how should the elasticity be reported?

A) $\varepsilon = \pm 0.004$
B) $\varepsilon = 0.172 \pm 0.002$
C) $\varepsilon = 0.172 \pm 0.004$
D) $\varepsilon = 0.172$
