Answer the following question given this paragraph: Specifically for the strong nuclear force, Yukawa proposed that a previously unknown particle, now called a pion, is exchanged between nucleons, transmitting the force between them. Figure 33.3 illustrates how a pion would carry a force between a proton and a neutron. The pion has mass and can only be created by violating the conservation of mass-energy. This is allowed by the Heisenberg uncertainty principle if it occurs for a sufficiently short period of time. As discussed in Probability: The Heisenberg Uncertainty Principle the Heisenberg uncertainty principle relates the uncertainties E in energy and t in time by. Q: The pion can only be created by violating the conservation of what? A:
****
A: mass-energy

Answer: female reproductive system

Question: Answer the following question given this paragraph: A monoprotic acid is an acid that contains only one ionizable hydrogen. Hydrochloric acid and acetic acid are monoprotic acids. A polyprotic acid is an acid that contains multiple ionizable hydrogens. Most common polyprotic acids are either diprotic (such as H 2 SO 4 ) or triprotic (such as H 3 PO 4 ). Q: Which acid contains only one ionizable hydrogen? A:
OPTIONS:
- citric acid
- lactic acid
- amino acid
- monoprotic acid
Answer: monoprotic acid

input: OPTIONS:
- gravity
- temperature
- energy
- time Now, answer this question: Answer the following question given this paragraph: The galaxies at the edge of the Universe are a great distance away. But they are something else that is distant. Because it takes so long for light from so far away to reach us, they are also very far back in time ( Figure below ). Q: Due to the time it takes for light to reach us, galaxies at the edge of the universe are distant in terms of space and what else? A:
A:
output:
time
