2. a. No. Scientist do not vote about their knowledge.
They use evidence to support or disprove scientific
arguments
1. a. mechanics (laws of motion)
b. vibrations and waves (sound or acoustics)
c. optics
b. No. Speed of light is determined in nature. We can
only measure it.
d. thermodynamics
c. Yes, by sharing their scientific arguments. Science is
a body of knowledge about the universe. Scientists
around the world work together to make it grow.
e. electricity
