To 5.00 m/s. How long does it take the car to decelerate if the force on the car is 8410 N to the east?

What are similarities and differences of reflection, refraction, diffraction and absorption?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

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
