Instructor: Physics Introduction This paper seeks to answer a number of questions relating to physics. The areas covered include amount of wasted heat, average temperature of exhaust gas, design, amount of energy generated, and finally and estimation of the installation and maintenance costs, size, and weight of your design…
The heat that is produced will be calculated from the amount of carbon dioxide that is produced. For a mile, the heat that is produced seems to be high in the first mile than in the next miles. The reason behind is that, in the first mile, there are additional heat changes that are produced as the automobile begins to accelerate (Stapleton, 200). Due to the fuel economy that has been used as a technique of manufacturing many automobiles, the amount of heat that is produced is limited since the automobiles are more automated. A modern car will produce less heat in a short period since the amount of petrol and diesel that is burned is less. When the amount of fuel that is burned in a short period is less, the heat that will be produced will be less. The size and density of the automobiles engine will also contribute to the amount of heat that will be produced. A big-sized engine is likely to produce more heat when compared to a small engine-sized automobile. In calculating the amount of heat that is produced in a mile, we will have to calculate Gallons per mile to get the real heat produced (Stapleton, 125). 2. What is the average temperature of the exhaust gas? The exhaust gas is estimated to have the same temperature to that of the engine at that particular time. It is usually tricky get the temperature since the exhaust gas since after it comes outside the engine other external factors immediately affect. Another factor that is likely to affect the real value of the temperature is the fact that the measurements will be calculated away from the place where combustion takes. The exhaust system as a whole will affect the right temperature of the exhaust gas (Stapleton, 112). In a case where gasoline and air are mixed in a proportion that will lead to complete combustion, the temperature of the exhaust gas is estimated to be 1500 F ranges. This temperature is estimated to be very high to cause catastrophe in the engine. Therefore, it is said that in most cases complete combustion does not occur (Stapleton, 205). Manufactures at most times will manufacture vehicles with a limited space for combustion so that complete combustion does not take place. At most, a case, the temperature that is estimated by manufactures is 1200 F to 1300 F range. This temperature can withstand the harsh conditions in the engine. When the temperatures range at these temperatures, the functioning of the engine will be proper. At proper temperatures, the combustion that will take place will be favorable functioning of the engine. At high temperatures, the pressure will be minimal thus proper working of the engine (Stapleton, 99). 3. Design a method to reclaim the thermal energy from the exhaust? It can be either electrical or mechanical energies The energy that is produced in the exhaust is in the most cases wasted into the atmosphere. This energy can be reclaimed through various methods. Some of them have been tried out but they have not showed any positive results. The methods to claim the energy can be electrical or mechanical. In my case, I am going to design an electrical method of reclaiming the energy (Stapleton, 211). In my model, the apparatus will be electrical wires that can be identified as positive and negative, cathode, and anode. In the model, the connections will bring from the combustion chamber where the exhaust gas will be directed ...

2. When jumping from a tree to the ground, the person moves at constant acceleration hence constant force. On hitting the ground, the person experiences an opposing force from the ground causing the body to lose momentum within a short time interval, hence need for more force leading to pain.
These questions have been responded to in a certain chronological order as follow. Frequencies encoding gradients, as well as phase encoding gradients areboth essential part of the spatially encoded data. It is, thus, true that using the induced differences in the frequency and the phase of precession, makes the data amenable for analysis by the Fourier transform.
But it gained an independent identity in 19th century. New discoveries constantly open new outlook for learning about nature. It is a way of looking at nature from the ground up, and has inspired the philosophies of the twentieth century. Today, the scope of physics is expanding through inter-relationship between various concepts like mechanics, heat, sound, light, electricity and magnetism leading to new fields including microbiology, nano- technologies and financial markets
the potential at a point on the surface due to the charge is Q/R. since potential inside a conductor is the same everywhere, this expression itself gives the potential of any point in the interior of the sphere. But the potential of a conductor is Q/C where C is the capacitance.
No single theory or model can provide complete explanation of the universe and its dynamics on an individual basis. The complete picture of the universe can be given only by such models that are capable of accounting for all the forces of nature-the three common forces and the gravitational force as well and this is exactly what the theorists and physicists have been searching for long (Hooft Gerard't, 2005).
Now the car changes direction, in the time interval of t3 – t4, and is accelerating in the opposite direction to the previous one, with the rate of 15 m /s2 up to a velocity of 15 m /s in the opposite direction.

The second principal is the Newton’s laws of motion that have been used to calculate the displacement, velocity and acceleration of objects under the influence of gravity either in free fall or in inclined motion.
