Cylinder with frictionless piston contains steam at 2 mpa, 500c with a volume 5l, as shown in fig p5.64. external piston force is proportional to the cylinder diameter cubed. heat is transfered out of cylinder, reducing the volume and thus the force until the cylinder pressure has dropped to 500 kpa. find work and heat transfer in this process

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

What is the relationship between the direction of motion of the balloon and the wind currents

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
