Two 400-mm diameter disks and a 240-mm diameter disk are joined 125 mm with respect to the axis of the spool. If a force P of 500 N is apploed to the spool through a cord that is wrapped around the cylinder, determine the acceleration aG of the mass center of the spool and the angular acceleration of the spool

lol

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

i don't understand. explain it clearly
