Asimple wheel has the form of a solid cylinder of radius r with a mass m uniformly distributed throughout its volume. the wheel is pivoted on a stationary axle through the axis of the cylinder and rotates about the axle at a constant angular speed. the wheel rotates n full revolutions in a time interval t. what is the kinetic energy k of the rotating wheel? answer in terms of m, r, n, t, and pi.

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
