Chapter 1, Problem 2P

Some scientists believe that the collision of one or more large asteroids with the Earth was responsible for the extinction of the dinosaurs. The unit of kiloton is used to describe the energy released during large explosions. It was originally defined as the explosive capability of 1000 tons of trinitrotoluene (TNT) high explosive. Because that expression can be imprecise depending on the explosive's exact chemical composition, the kiloton subsequently has been redefined as the equivalent of 4.186 x 1012 J. In the units of kiloton, calculate the kinetic energy of an asteroid that has the size (box-shaped, 13 x 13 x 25 km) and composition (density, 2.4 g/cm) of an asteroid. Kinetic energy is defined by U. = mv? where m is the object's mass and v is its speed. Objects passing through the inner solar system generally have speeds in the range of 20 km/s. (Express your answer using two significant figures.) Uk = x1011 kilotons

Express the specific weight, in U.S. Customary units(lb / in.3), of a specimen of material that has a density of4500 kg/ m3

A commonly used unit in everyday language to state weight is the pound (lb). There are actually several formal definitions of pound. One classification system defines a pound-mass (analogous to kg in SI units) and a pound-force (lbf) (analogous to a Newton); this is formally called English Engineering units but also commonly used in US Customary System units. The “pound” in the “pounds per square inch” of psi refers to pound-force. Hence, psi has units of force per area. Note that 1 lbf is defined as the gravitational force generated by 1 lb (mass) by multiplying it by the standard gravitational acceleration at the earth’s surface. Starting with just the two everyday conversion approximations every Canadian should know (1.00 kg ≈ 2.20 lb (mass) and 1.00 inch ≈ 2.54 cm), derive an approximation of 1.00 psi in Pa through unit conversions only (show each step).

please only c and d

Handwritten and the unit should be in metric system. Three kilograms of water at 35 degrees Celsius are placed in a piston under 4.335MPa (State 1). Heat is added to the water at constant pressure until the piston reaches a stop at a total volume of 0.55 m3 (State 2). Most heat is added at constant volume until the temperature of water reaches 425 degrees Celsius (State 3). Determine (a) the quality of fluid and the mass of the vapor at State 2, and (b) the pressure of the fluid at State 3.
