Pick three different trials that have a different mass ratio. Determine the ratio of mred/mblue and vred/vblue for the post explosion data. What is the rule that describes how to predict the relative velocities of the two carts after the explosion

Modify the equation fδt=δ (mv) to find the force of friction.

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
