Question

The hypotheses relating to the discoveries of radium and Neptune may be classified as empirical hypotheses.

a) true
b) false

Answer 1

a) true

Explanation:

Empirical hypothesis is the type of hypothesis used to try and explain a phenomenon which leads to a theory been developed and put to the test, using observation and experiment.

Radium was discovered due to a discrepancy in pitchblende's radiation. It was noted by the Curies that Polonium alone could not suffice for that amount of radiation, leading to the theory that another element could be present. After further testing, Radium was discovered as the culprit element.

Also, the presence pf another planet, later discovered to be Neptune was theorized to explain the phenomenon that could cause the irregularities in the motion pattern of the planet Uranus. After much experimentation, observations and calculations, Neptune was discovered.
