Answer the following question given this paragraph: 8.1 Linear Momentum and Force Linear Momentum The scientific definition of linear momentum is consistent with most people's intuitive understanding of momentum: a large, fastmoving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as. Q: The product of a system's mass multiplied by its velocity is called what? Choices: - variation momentum - magnetic momentum - horizontal momentum - linear momentum A:
linear momentum
Answer the following question given this paragraph: Amino acids can bond together through peptide bonds to form short chains called peptides or longer chains called polypeptides ( Figure below ). A peptide bond is a covalent bond formed from a condensation reaction between two molecules, causing the release of a molecule of water. This bond usually forms between two amino acids, hence forming a peptide or polypeptide. Peptide bonds between amino acids are formed during the process of translation. Q: When are peptide bonds between amino acids formed? Choices: - process of transcription - process of migration - process of production - process of translation A:
process of translation
Q: Answer the following question given this paragraph: The physical properties of gases are predictable using mathematical formulas known as gas laws. Q: The physical properties of gases are predictable using mathematical formulas known as what? Choices: - air laws - vapor laws - state laws - gas laws A:
A: gas laws
Question: Answer the following question given this paragraph: Velocity is defined as change in position over time. Can you see that would be the slope of this graph? (slope = rise over run and in this case the 'rise' is position and the 'run' is time). Find the instantaneous speed at sec. Q: What term refers to change in position over time? Choices: - Position Replacement - acceleration - Direction Replacement - velocity A:
Answer: velocity

Answer the following question given this paragraph: Primary Batteries Primary batteries are single-use batteries because they cannot be recharged. A common primary battery is the dry cell (Figure 17.10). The dry cell is a zinc-carbon battery. The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc: Zn(s) Zn 2+(aq) + 2e . Q: Primary batteries are single-use batteries because they cannot be what? Choices: - UP ticked. - refreshed - plugged - recharged A:
**Answer**
recharged
Answer the following question given this paragraph: Arteries are muscular blood vessels that carry blood away from the heart. They have thick walls that can withstand the pressure of blood pumped by the heart. Arteries generally carry oxygen-rich blood. The largest artery is the aorta, which receives blood directly from the heart. It branches to form smaller and smaller arteries throughout the body. The smallest arteries are called arterioles. Q: What is the name of muscular blood vessels that carry blood away from the heart? Choices: - tubes - Veins - Aorta - arteries A:
arteries
