Module 5- Real-World Physics Discussion

During lab, Table Group 9 accidentally launches their spring from the tabletop onto the light fixture shown in the diagram. The spring has a mass of 12 grams. The instructor gave clear instructions not to stretch the spring by more than 70 cm to protect it from damage. If this spring's stiffness is k= 15 N/m, did the group follow instructions or did they stretch the spring too far? 3.0 m 1.2 m

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

The crux of the problem asks you to compute the elastic modulus of a pancake--for this we give you numbers that we got from our own measurements of the pancakes. The last question asks you to hypothesize about which ingredients are playing the role of flour in the gluten free recipes. If you find this topic interesting, you may want to consider exploring something like this for your final project, and design an experiment to understand the difference between the normal and gluten free recipe and try to manipulate the gluten free recipe to better resemble the normal pancakes.If you choose to make the two recipes and compare them in your own kitchen, make sure you use exactly the same protocol for each recipe: In our trials, we made the batter, and then cooked on a skillet, using 1/4 cup of batter per pancake, and flipped when the edges were firm and golden, about 4-5 minutes on each side.Consider a stack of six pancakes. Each pancake is made of 1/4 cup (approximately 60 mL) of batter,…

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).

You are building additional storage space in your garage. You decide to suspend a 10.0 kg sheet of plywood of dimensions 0.600 m wide by 2.25 m long from the ceiling. The plywood will be held in a horizontal orientation by four light vertical chains attached to the plywood at its corners and mounted to the ceiling. After you complete the job of suspending the plywood from the ceiling, you choose three cubic boxes to place on the shelf. Each box is 0.750 m on a side. Box 1 has a mass of 50.0 kg, Box 2 has a mass of 100 kg, and Box 3 has mass of 125 kg. The mass of each box is uniformly distributed within the box and each box is centered on the front-to-back width of the shelf. Unbeknownst to you, one of the chains on the right-hand end of your shelf is defective and will break if subjected to a force of more than 700 N. There are six possible arrangements of the three boxes on the shelf, for example, from left to right, Box 1, Box 2, Box 3, and Box 1, Box 3, Box 2, and four more. Which…

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.

What trigonometric identity may be used to summarize an equation for calculating tension force (the long equation you'll use before replacing the values)? What do you think the role of mass is in determining the net acceleration of an item rolling down an incline? Friction is a significant factor. Why is the normal force no longer equal to the weight of all things on an incline?

Thermodynamics - Dr. Suhaib Shbailat 1-101 Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as F, = Pains Voallonr will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 85 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is p = 1.16 kg/m², and neglect the weight of the ropes and the cage. Answer: 22.4 m/s? Helium D= 12 m PHe =7 Pair Hello, please solve the quesțion without explanation with mentioning my name in ((morteza Ali Qasim))))paper and a beautiful font. Thank you doctor. Don't forget my name, please, God bléss you m= 170 kg FIGURE P1-101

An increasing number of Americans are moving to a warmer climate when they retire. To take advantage of this trend, Sunny Skies Unlimited is undertaking a major real-estate development project. The project is to develop a completely new retirement community (to be called Pilgrim Haven) that will cover several square miles. One of the decisions to be made is where to locate the two paramedic stations that have been allocated to the community to respond to medical emergencies. For planning purposes, Pilgrim Haven has been divided into five tracts, with no more than one paramedic station to be located in any given tract. Each station is to respond to all the medical emergencies that occur in the tract in which it is located as well as in the other tracts that are assigned to this station. Thus, the decisions to be made consist of (1) the tracts to receive a paramedic station and (2) the assignment of each of the other tracts to one of the paramedic stations. The objective is to minimize…

2 Your friend is planning to ride his bike up a ramp and land on the roof of a building as shown below. The building is 6.00 m high and 8.00 m away from the ramp. The ramp is 3.00 m wide and 4.00 m tall. 4.00 m 1 ← 3.00 m 6.00 m 8.00 m A. What is the minimum speed with which your friend needs to leave the ramp in order to land on the building? B. Another friend is going to use his motorized scooter for the same stunt. The maximum speed of the scooter is 15.0 m/s. How close to the building should you move the ramp so that your friend lands on the roof right at the front edge of the building?

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. ?
