<span>The hypothesis must be testable and falsifiable. The first stipulation is that the hypothesis must be able to be tested and be phrased as such. In addition, the second stipulation holds that the statement must be able to be falsified; that is, the statement can be showed to not be the case.</span>
Answer:
Their experimental design lacks control group
Explanation:
Based on what I read, the scientists don't have a control group as one of the main groups thus they cannot, in scientific sense, say that the medicine is better or worse. You always need a control group receiving no intervention because then we can compare groups and assess the effectiveness of that intervention (in our case if we had control group vs people who received the medicine, we could see if the people who received the medicine had improved condition etc when compared to participants who did not receive anything)
It must be either speeding up, or slowing down, or turning. There are no other possibilities.

Answer:
temperature and mass
Explanation:
- The higher the temperature of a given quantity of a substance, more is its thermal energy.
- If a substance contains more mass, this also implies that the object has more particles in it . hence, it has high thermal energy.

- Temperature is a measure of the average kinetic energy of the particles of a substance.
- The thermal energy of an object depends on three factors:
- number of molecules in the object
- temperature of the object.
- thermal energy it has.
