Ques: Answer the following question given this paragraph: p = F nett, we can see how the change in momentum equals the average net external force multiplied by the time this force acts. The quantity F net t is given the name impulse. Impulse is the same as the change in momentum. Impulse: Change in Momentum Change in momentum equals the average net external force multiplied by the time this force acts. Q: Change in what equals the average net external force multiplied by the time this force acts? Choices: - lag - height - rate - momentum A:
Ans: momentum

Ques: Answer the following question given this paragraph: Visible light is only a small part of the electromagnetic spectrum. There are parts of the electromagnetic spectrum that humans cannot see. This radiation exists all around you. You just can't see it! Every star, including our Sun, emits radiation of many wavelengths. Astronomers can learn a lot from studying the details of the spectrum of radiation from a star. Q: What does every star emit that humans cannot see? Choices: - sound - light - dust - radiation A:
Ans: radiation

Ques: Answer the following question given this paragraph: Beneath the crust is the mantle . The mantle is made of hot, solid rock. Through the process of conduction, heat flows from warmer objects to cooler objects ( Figure below ). The lower mantle is heated directly by conduction from the core. Q: What layer, made of hot, solid rock, is beneath the earth's crust? Choices: - marble - core - magma - mantle A:
Ans:
mantle
