Jonah and Isaac have begun their experiment for science class (see source 2 in part 2). Write a procedure using their materials that they could follow to test their hypothesis. Scientific Question: How does the mass of an object and the force applied to it affect its acceleration?
Materials: a meter stick, a stopwatch, different types of balls with different masses
Hypothesis: If we apply a force to balls with less mass, then they will accelerate more than balls with more mass when acted upon with the same size force

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
