I’m begging. answer these questions. ah my life needs . . (need in 2 hours)

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?

What os the equation of the line described below written in slope-intercept form? the line passing through point (0,0) and parallel to the line whose equation is 3x+2y-6=0
