Ques: Answer the following question given this paragraph: Figure 28.18 Momentum is an important concept for these football players from the University of California at Berkeley and the University of California at Davis. Players with more mass often have a larger impact because their momentum is larger. For objects moving at relativistic speeds, the effect is even greater. (credit: John Martinez Pavliga). Q: Why do players with more mass often have a larger impact in football? Choices: - potential energy is lower - kinetic energy is lower - Velocity is larger - momentum is larger A:
Ans: momentum is larger

Ques: Answer the following question given this paragraph: Fertilization of an egg by a sperm in a fallopian tube produces a zygote. The zygote develops into a blastocyst, which implants in the uterus. The offspring then goes through the embryonic and fetal stages. The placenta supports the needs of the developing embryo and fetus. Birth generally occurs at about 38 months after fertilization. Q: What is produced when an egg is fertilized by a sperm in a fallopian tube? Choices: - uterus - fetus - ovaries - zygote A:
Ans: zygote

Ques: Answer the following question given this paragraph: Mass is independent of location, while weight depends on location. Q: What is a factor in determining weight but not mass? Choices: - function - material - gravity - location A:
Ans: location

Ques: Answer the following question given this paragraph: Q: "crossing over" occurs during what phase of mitosis? Choices: - Prophase ii - prophase VI - prophase iii - prophase i A:
Ans:
prophase i
