a. Find the center of mass for lamina defined by the interior of
the polar curve r=sin(3) with a density
that varies according to p(r,theta)=1/r
b. Find the volume of the cylinder inside the sphere
For part a I got a mass of 2 but not sure about the x bar and y
bar calculations.
For part b Im stuck on the z bounds for the integral when doing
the problem with the cylindrical coordinate method.
We were unable to...
Chapter 7, Section 7.3, Go Tutorial Problem 054 x Incorrect. A radioactive substance decays at a constant percentage rate per year. Find the half-life if it decays at a rate of (i) 14% per year Half-life = -4.951 U years. Round the answer to 3 decimal places. (ii) 27% per year Half-life = -2.567 U years.
