Tutorial of Modern Physics 1) A light of wavelength 445 nm falls on a piece of metal. The maximum energy of the electron doubles when light of wavelength 225 nm is used. Find the work function in eV. ​

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

that would be because of both gravity and friction. so     c
