Aparticle with a charge of 33 μc moves with a speed of 74 m/s in the positive x direction. the magnetic field in this region of space has a component of 0.41 t in the positive y direction, and a component of 0.86 t in the positive z direction. part a what is the magnitude of the magnetic force on the particle? express your answer using two significant figures.

More solar radiation is absorbed by earth’s surface than by

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
