Scientists earlier believed that the lowest measurable temperature is the freezing point of ice. however, modern scientists believe that temperatures below the freezing point of ice can also exist. what best accounts for these different opinions? scientists propose contradictory ideas to include all possibilities scientists come up with different hypotheses without enough evidence scientists propose different ideas to avoid repetition of scientific knowledge scientists having different interests may interpret the same data in different ways

The statement that best accounts for these different opinions is: scientists propose contradictory ideas to include all possibilities. This statement refers to the scientific method, that is a set of different techniques for investigating phenomena and gaining new knowledge that can improve or correct the previous one. As a result, analysis based on contradicting opinions leads to the progress in scientific sphere.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
