Calculate the flux through the sheet of the previous problem if the plane of the sheet is at an angle of 60° to the field. find the flux for both directions of the unit normal to the sheet.

Which statement correctly describes the relationship between frequency and wavelength?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
