Q3: Amplitude and period in SHM A block attached to a spring oscillates in simple harmonic motion along the 3 axis. The limits of its motion are x = 10 cm and r = 50 cm and it goes from one of these extremes to the other in 0.25 s. Its amplitude and frequency are: A. 40 cm, 2 HZ B 20 cm, 4 HZ C. 40 cm, 2 Hz D. 25 cm. 4 Hz E 20 cm, 2 Hz ОА B Ос D E

you have to draw the persons position over there

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

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.
