Module 5- Real-World Physics Discussion

1. The development of thermodynamics since the 17th century, which was pioneered by the invention of the steam engine in England, and was followed by thermodynamic scientists such as Willian Rankine, Rudolph Clausius, and Lord Kelvin in the 19th century. explain what the findings or theories of the 3 inventors are! Please answer fast max 25-30.minutes thank u

Answer question 4 please. Make sure it’s correct and explain the steps please.

PLEASE SOLVE THE FOLLOWING THREE QUESTIONS Question G: Generally speaking, (no numbers required), at what point does Newton's Model of Cooling (T=A+Be^kx) (when regarding dead bodies' temperatures) no longer work? What in reality gives us an indication that we’ve taken it too far?   Question H: Assuming that the temperature of the person at the time of death (TOD) was 98.6 °F, set up a TOD equation using the values of ,A, ,B, and k you’ve calculated. Then, solve the equation using the same logarithm method you used to solve for .k. A: 68 Farehneits, B: 17.9 Fareinheit K: -0.002564 TOD: 98.6 Fareinheit  Plug the above info into Newton's law of cooling: (T=A+Be^kx) Write your answer as a time, not just as x minutes. Recall that when ,x=0, the time is 2:00 PM.   Question I: When forensic expert determines the time of death, they often have additional information besides body temperature. Suppose a coroner finds that the person who was murdered had an infection that probably raised the…

I need help with this before tomorrow’s exam if I can get all needed calculations please

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

The weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out of existence. Under such extreme conditions, protons and electrons are squeezed to form neutrons, giving birth to a neutron star. Neutron stars are massively heavy - a teaspoon of the substance of a neutron star would weigh 100 million metric tons on the Earth. a) Consider a neutron star whose mass is twice the mass of the Sun and whose radius is 13.3 km. (The mass of the Sun is 1.99-1030 kg.) If it rotates with a period of 2.57 s, what is the speed of a point on the Equator of this star? Submit Answer Tries 0/99 b) What is the value of g at the surface of this star? Submit Answer Tries 0/99 c) Compare the weight of a 1.30-kg mass on the Earth with its weight on the neutron star. How many…

please solve these question carefully , please make sure its correct , i just want final answer of all the three questions . i will rate if all are correct. Please answer all ( details not requried )

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

Simple Machines-Levers, Inclined Planes, and Pulleys Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your Engineering Design journal. Remember to show all work. A lever has an effort arm that is 5 meters long and a resistance (load) arm that is 3.5 meters long. How much effort is needed to lift a 100 Newton weight? 5K i). Draw the figure representing the problem ii). How much effort is needed to lift a 100 Newton weight? iii). What is the Actual Mechanical Advantage 1. 5m i) AOON 5-5m

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

please help me with this

Question #5 (Similar to Question #4, You solved, I have attached the question #4)Design a question to calculate the heating load for the building you selected indoor Environment Quality (IEQ) assessment. You will define the types of heat loss (at least two types) in that building (or the floor you are working on or you are familiar with). The indoor temperature is set as 75 F, and you can assume the outdoor temperature based on the location of your building in the winter and any other numbers needed to resolve this question. For all the details as well as the final answer that this question is asking for, clearly indicate the unit for each piece of information.

Please help answer the question regarding heat transfer. I tried solving it and came up with 152.56 oC but it says that it is incorrect. Please show how to get the correct answer. Thank you.

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

Please help with question 2 only.
