A solid spherical mass M-58.6 kg and radius 13.2 cm is concentric with a thin spherical shell M -86.4 kg and radius 32.3 cm as shown. A point mass m - 245 grams is at a distance of 22.8 cm from the center of the solid sphere. Determine the magnitude of the gravitational force on m. a....
3. (a) Let f be an infinitely differentiable function on R and define F(x) = [-vf(u) dy. Find and prove a formula for F(n), the nth derivative of F. (b) Show that if f is a polynomial then there exists a constant C such that F(n)(x) = Cea for sufficiently large n. Find the least n for which it is true.

→ (1 point) Let Vf-6xe-r sin(5y) +1 5e* cos(Sy) j. Find the change inf between (0,0) and (1, n/2) in two ways. (a) First, find the change by computing the line integral c Vf di, where C is a curve connecting (0,0) and (1, π/2) The simplest curve is the line segment joining these points. Parameterize it: with 0 t 1, K) = dt Note that this isn't a very pleasant integral to evaluate by hand (though we could easily...
