A stationary block has a charge of +6.0Γ10β8 C. A 0.80-kg cart with a charge of +4.0Γ10β8 C is initially at rest and separated from the block by 0.4 m. The cart is released and moves along a frictionless surface to a distance of 1.0 m from the block. Consider the objects as point charges.
A) Determine the electric potential energy of the initial state.
B)Determine the electric potential energy of the final state.
C)Determine the change in electric potential energy.
D)Determine the final speed of the cart. Assume that the change in electric potential energy is fully transformed into kinetic energy of the cart.

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/(mβ
k), and the styrofoam has k= 0.010 w/(mβ
k). the interior surface temperature is 19.0 βc , and the exterior surface temperature is -15.0 βc . 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
