Estimate the probability of finding an electron which is excited into the 2s orbital of the h atom, looking in a cubical box of volume 0.75 × 10236 m3 centered at the nucleus. then estimate the probability of finding the elec- tron if you move the volume searched to a distance of 105.8 pm from the nucleus in the positive z direction. (note that since these volumes are small, it does not mat- ter whether the volume searched is cubical or spherical.)

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
