Question: Suppose a pillar (density exactly 2567 kg/m3) is in the shape of a cylinder 5.06m ± 0.08m high and radius 2.42m± 0.17m.
Part A: Find the mass of the pillar and its uncertainty.
I need help to solve the above question. HINT: Find the uncertainty in r2 first, and then find the uncertainty in the entire expression.

question a 575 ohms resistor and a 260mh inductor are connected in series with an ac generator with an rms voltage of
A long, thin rod (length = 5.0 m) lies along the x axis, with its midpoint at the origin. In a vacuum, a +7.0C point charge is fixed to one end of the rod, and a -7.0C point charge is fixed to the other end. Everywhere in the x, y plane there is a co..
How much work must be completed to accelerate a baton from rest to an angular speed of 7.79 rad/s about its center? Consider the baton to be a uniform rod of length 0.596m and mass 0.495kg.
