I believe a hypothesis is determined before experimentation begins. A hypothesis is a scientific state of prediction. It describes in concrete terms what you expect will happen in ones study. However, not all studies have hypothesis. Often times a study may be designed to be explanatory. A study may have one or more hypothesis. Hypothesis is an educated prediction that can be tested.<span />

anyanavicka [17]

Answer:

The answer to your question is 5.4 cm

Explanation:

This problem refers to calculate the change in length in one dimension due to a change in temperature.

Data

α = 12 x 10⁻⁶

Lo = 150 meters

ΔT = 30 °C

Formula

                    ΔL/Lo = αΔT

solve for ΔL

                    ΔL = αLoΔT

Substitution

                    ΔL = (12 x 10⁻⁶)(150)(30)

Simplification

                    ΔL = 0054 m = 5.4 cm
