Tia, from the blog "Talk to Tia," asked her readers, "If you had to do it over again, would you take more college prep courses in high school?" Of the 1,500 readers who responded, 65% said no. What does this show? (4 points) No meaningful conclusion is possible without knowing something more about the characteristics of her readers.
The survey would have been more meaningful if Tia had picked a random sample of the readers who responded.
The survey is meaningless because of voluntary response bias.
The survey would have been more meaningful if Tia had used a control group.
This was a legitimate sample, drawn randomly from her readers, and is of adequate size to allow the conclusion that most of Tia's readers who are college-bound high school students would not have taken more college prep courses.

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
