During a stress-strain test, the unit deformation at a stress of 35 MPa was observed to 0.00000167 m/m and at a stress of 140 MPa it was 0.00000667 m/m. If the proportional limit was 200 MPa, what is the strain corresponding to 80 MPa?

iron would move it is magnetic there is a mag field around the current in the wire

radiation

explanation:

heat is transmitted by radiation

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.
