Which statement would most likely explain why the results of one new experiment did not support an accepted hypothesis?

a. there was a flaw in the experiment’s design or errors when it was conducted.
b. two different theories about the subject are both true at the same time.
c. the hypothesis was false, and scientists should replace it with a new one.
d. the question that originally inspired the hypothesis was not fit for scientific inquiry.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
