Textbook Question
Chapter 13, Problem 51IF
Cruise Ship Energy. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about 100 million kilograms, and we want to accelerate the ship to a speed of 10% of the
- a. How much energy would be required? (Hint: You can find the answer simply by calculating the kinetic energy of the ship when it reaches its cruising speed; because 10% of the speed of light is still small compared to the speed of light, you can use the formula that tells us that kinetic energy =
- b. How does your answer compare to total world energy use at present, which is about 5 × 1020 joules per year?
- c. Suppose the cost of energy is 3¢ per 1 million joules. At this price, how much would it cost to generate the energy needed by this spaceship?

Using the GUFSA Template. Round off your final answer to the nearest hundredths. As we already know, rockets travel at very high speeds. How much time will it take a rocket (in seconds) to reach the moon if the moon is 238,900 miles away from the Earth, and the rocket is travelling 1,800,000 centimeters per minute? (express your answer in meters per second)

Hello from 2042!
(A letter from students’ future selves, narrating their lives 20 years after Senior High School Graduation and how the world looks like. There should be an in-depth discussion how the letter was able to reach their present selves by integrating concepts on the Postulates of Special Relativity and their consequences.

- What do we mean by mass-energy? Is it a form of kinetic, radiative, or potential energy? How is the idea of mass-energy related to E = mc2? Explain how E = mc2 is at work in our Sun to produce the light and the heat emitted by the star.arrow_forwardIn this chapter, we identify these characteristic properties of life: life extracts energy from its environment, and has a means of encoding and replicating information in order to make faithful copies of itself. Does this definition fully capture what we think of as “life”? How might our definition be biased by our terrestrial environment?arrow_forwardThe Drake equation In 1961 astronomer Frank Drakedeveloped an equation to try to estimate the number ofextraterrestrial civilizations in our galaxy that might be able to communicate with us via radio transmissions. Nowlargely accepted by the scientific community, the Drakeequation has helped spur efforts by radio astronomers tosearch for extraterrestrial intelligence. Here is the equation: NC = N # fp # ne # fl# fi# fc # fLOK, it looks a little messy, but here’s what it means:So, how many ETs are out there? That depends; valueschosen for the many factors in the equation depend onever-evolving scientific knowledge and one’s personalguesses. But now, some questions.a) What quantity is calculated by the first product, N # fp?b) What quantity is calculated by the product, N # fp # ne # fl?c) What probability is calculated by the product fl# fi?d) Which of the factors in the formula are conditionalprobabilities?

Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At least one of your scenarios should be at the molecular level. Would the implications be positive? Negative? Explain.arrow_forwardDescribe rest energy, and explain how it can be converted to other forms.arrow_forward
