Iknow this is in mathematics but nobody answers in chemistry so i need ! mike chose to do a science project on the way that gravity and electricity can both create an attracting force. he set up a model of the earth-moon system for part of his project, and then he made an electromagnet with copper wire and an iron core. in his demonstration, he picked up paperclips by waving the electromagnet several inches over the clips on the table. he also explained how the earth and the moon each exert a force on the other, causing the tides. a good title for mike's science project would be a. the solar system and tidesb. electromagnetsc. noncontact forcesd. contact forces

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy
