- The energy released from condensation in thunderstorms can be very large. Calculate the energy (in J) released into the atmosphere for a small storm of radius 2.6 km, assuming that 2.5 cm of rain is precipitated uniformly over this area. (Assume that the rain is precipitated over a circular area and that the density of water is 1000 kg/m3.) _________JFor most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case.A sample of gas is compressed to one-third of its initial volume at a constant pressure of 1.25 × 105 Pa. During the compression 100J of work is done on the gas. What is the final volume of the gas?
- Q20: Dr. Fahrrad has been riding his bike to his job and is curious how many ATP his body is breaking apart in order to do the work required to get to his job. Dr. Fahrrad rides 8.6 kilometers to his job, has a mass of 68.4 kilograms and has an average acceleration of 2.4 kilometers per second squared. The molecule ATP is able to do work, measured in kilojoules per mole of ATP broken into ADP. The SI unit for work is a joule. Using the information given we can calculate work and then convert to moles of ATP. The first step is to take stock of what we are given in the word problem and what we are trying to find. We have mass, distance, and average acceleration. We are trying to find how many ATP are required to power the bike ride to work. The equation for work, is force times distance and will tell us how many joules Dr. Farrhad is using on his bike ride. It also incorporates one of our given variables, distance. However, the distance was reported in kilometers and the SI unit of…A 53−kg person drinks5.4×102g of milk, which has a caloric value of approximately 3.0 kJ/g.If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation. Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration(9.8 m/s2), and h is the height (in meters).Please help me
- An air-filled cylinder with a movable piston has a heat reservoir in contact with it. The heat reservoir transfers 850 J of energy into the cylinder. Due to the energy transfer, the piston does 437 J of work on the environment. What is the change in internal energy of the system?Answers (~1.9kJ, ~1.1kJ, ~4kJ) The figure to the right shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft with a cross- sectional area of 1.0 cm² is attached to the top of the piston. The total mass of the piston and shaft is 35 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.25 kJ, the potential energy of the piston-shaft combination increases by 0.5 kJ, and a force of 1300 N is exerted on the shaft as shown in the figure. The piston and cylinder are both good insulators and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s². Determine: 21 F-1300N (c) the heat transfer to the gas (kJ) (d) Provide a detailed accounting of where all of the heat energy has gone. C 19 4 A-14cm (a) the work done by the shaft (kJ) (b) the work done in displacing the atmosphere (kJ) (atmosphere does not act on shaft aka a donut area) D²10.0Gas in a cylinder similar to the one shown in the figure moves a piston with area 0.207 m2 as energy is slowly added to the system. If 2.27 103 J of work is done on the environment and the pressure of the gas in the cylinder remains constant at 1.01 105 Pa, find the displacement of the piston.
