1. When a comet makes a close encounter with Jupiter, the shape of the comet's orbit around the sun changes. Comets are objects made up of ice and dust that are found in the solar system. Like planets, comets travel through the solar system in an orbit. The orbit of a comet often cuts across the orbits of planets.

Select two factors you would include in a model to best explain the change in the shape of the comet's orbit around the sun when the comet travels close to Jupiter.

A. the comet's inertia
B. the sun's magnetic field
C. the sun's gravitational pull
D. the comet's magnetic field
E. Jupiter's magnetic field
F. Jupiter's electrical force
G. Jupiter's gravitational pull

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

An object weigh 40n in air ,weigh 20n when submerged in water, and 30n when submerged in a liquid of unknown liquid density. what is the density of unknown of liquid?
