PLEASE HELP IM IN THE MIDDLE OF A TIMED TEST A force of 5.78x10^-16N acts on an unknown particle traveling at a 90° angle through a magnetic field. If the velocity of the particle is 5.65x10^4
m/s and the magnetic field is 3.20x10^-2T, find the charge of the unknown
particle in Coulombus

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
