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.

answer

the arrows to the right of earth should point up.

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
