Three dimensions. three point particles are fixed in place in an xyz coordinate system. particlea, at the origin, has massma. particleb, at xyz coordinates (2.00d, 1.00d,2.00d), has mass 2.00ma, and particle c, at coordinates (-1.00d, 2.00d, -3.00d), has mass 3.00mn. a fourth particled, with mass 4.00ma, is to be placed near the other particles. in terms of distance d, at what (a) x, (b) y, and (b) z coordinate should d be placed so that the net gravitational force on a from b, c, andd is zero?

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
