Thunderstorms that form east of the rocky mountains obtain their moisture primarily from evaporated water from the gulf of mexico. that water vapor, when condensed within a thunderstorm, creates the thunderstorm’s clouds and vast amounts of energy are released into the atmosphere in the form of latent heat. let’s calculate how much water and energy is in a large thunderstorm complex. determine the total number of gallons of water in this storm and also the total energy released in the storm expressed in megatons and joules. you must show your work to get credit. assumptions: each cubic centimeter (cm3) contains 7.5*10-7 grams of water (7.5*10-7 g/cm3) the storm’s dimensions are 60 km wide, 400 km long and 12 km tall. 1 gallon of water = 3785 grams of water each gram of water in the cloud releases 2260 joules of energy as it condenses (2260 j/g) a 1-megaton nuclear bomb releases 4.18 x 1015 joules of energy

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
