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

Solve question 2 based on the answer of question 1.  You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU:  1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon   Natural Gas BTU= 80,698,000  Oil BTU                = 71,512,440    The home that used a natural gas furnace used more energy for heating. 2.- You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of the fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…

The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093

Answer question 2 based on the results of question 1. You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter.

Thermodynamics Please READ THE PROBLEM! I’m tired of posting the same problem over and over. please Read. This is what the asking for please: -1. sketch and label all your answers on the nozzle -2. Sketch and label all your answers on the process on a P-V diagram.... Thank you

Need help with this question asap waited over 2 hours.

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

Please explain and answer

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

What’s the correct answer 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…
