On earth, froghoppers can jump upward with a takeoff speed of 2.8 m/s. suppose you took some of the insects to an asteroid. if it is small enough they can jump free of it and escape into space. (a) what is the diameter (in km) of the largest spherical asteroid from which they could jump free? assume typical asteroid denisty of 2.0 g/cm^3. (b) suppose that one of the froghoppers jumped horizontally from a small hill on an asteroid. what would the diameter (in km) of the ateroid need to be so that the insect could go into a circular orbit just above the surace?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
