The gaia satellite data release 2 measured the parallaxes of stars to an accuracy of better than 20 mas (a milliarcsecond, mas, is a thousandth of an arcsecond, which is on 3600th of a degree). to what distance, in parsecs, can we measure the largest parallax error stars with a distance error of better than 10%? you can use the general equation for error: σy=|dy/dx|σx, where σx is the measured error and σy is the error in the calculated value.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
