Module 5- Real-World Physics Discussion

Consider that the tropical ocean is exposed to direct sunlight for many hours every day. If the top 1cm of an area of water 10,000,000 cm by 10,000,000 cm warms from 25 to 27 degrees, how much heat energy, in Joules, has the water absorbed? (Every cm' of water has one gram of mass.) Remember the specific heat of water is 4.18 J/g°C

Chat I Review I Constants The Dyson sphere is an hypothetical spherical structure centered around a star. Inspired by a science fiction story, physicist Freeman Dyson described such a structure for the first time in a scientific paper in 1959. His basic idea consisted of an artificial spherical structure of matter built around a star at a distance comparable to a planetary orbit, with the purpose of capturing the energy radiated by the star and reusing it for industrial purposes Assume the mass of the sun to be 2.00x1030 kg Part A Consider a solid, rigid spherical shell with a thickness of 100 m and a density of 3900 kg/m. The sphere is centered around the sun so that its inner surface is at a distance of 1.50x1011 m from the center of the sun. What is the net force that the sun would exert on such a…

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

I want to briefly summarize what he is talking about and what you conclude. pls very urgent

Help!!! Please answer it correctly

3. This problem will help you understand why the wind blowing makes you feel colder, especially in the winter. You are outside on a cold day. The air temperature overall is around 5° C; assume your skin temperature is 16° C a) If you stay outside for a while and there is no wind, the air around you will eventually increase in temperature past 5° C. Explain why the air heats up, using the idea of conduction. b) What is the highest temperature the air around you can reach? Explain. c) As the air around you warms up, explain why you start cooling down more slowly. d) If the wind blows, convection happens: the warm air around your body is blown away, replaced by more 5° C cold air. In this case, will you cool down more quickly or more slowly? Explain. e) Explain why the "wind chill" temperature (ie, the temperature it feels like when the wind is blowing) is colder than the actual temperature of the air.

4. For each of the situations in trie lapie welow, state the process by which heat is transferred. Getting burnt by touching a hot stove Hot air rising, cooling and falling Heat from a campfire when you are seated beside it Ice cooling down your hand Heat from the Sun warming your face Boiling water by thrusting a red-hot piece of iron into it A slice of bread placed undera red-hot electric grill to make toast Heating a tin can of water using a Bunsen burner

⦁ A hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be? Remember to pay close attention to the units of temperature before beginning your calculations.

A Review I Constants You decide to visit Santa Claus at the north pole to put in a good word about your splendid behavior throughout the year. While there, you notice that the elf Sneezy, when hanging from a rope, produces a tension of 415 N in the rope. Part A If Sneezy hangs from a similar rope while delivering presents at the earth's equator, what will the tension in it be? (Recall that the earth is rotating about an axis through its north and south poles.) Express your answer with the appropriate units. ?

Summarize how at least two reference materials relate to the basic scientific principles of flying a paper plane. Each reference material must come from a different source. Be sure to describe how the references provide a foundational background for the experiment.
