Question Solved1 Answer https://phet.colorado.edu/en/simulation/the-ramp A file cabinet is traveling down a frictionless ramp tilted at 10 degrees. with horizontal. The final cabinet has a mass of 100kg and is at a height of 10m A.) 10. Calculate the speed of the filing cabinet at the bottom of the ramp: b.)Use the distance it traveled down the ramp, along with the initial speed down the ramp, and the time down the ramp (in the top right corner) to also calculate final speed. Is this value close to the value you found above?

As a laudably skeptical physics student, you want to test Coulomb's law. For this purpose, you set up a measurement in which a proton and an electron are situated 893 nm from each other and you study the forces that the particles exert on each other. As expected, the predictions of Coulomb's law are well confirmed. You find that the forces are attractive As a laudably skeptical physics student, you want to test Coulomb's law.

JAVA language Given a sorted list of integers, output the middle integer. A negative number indicates the end of the input (the negative number is not a part of the sorted list). Assume the number of integers is always odd. Ex: If the input is: 2 3 4 8 11 - 1 the output is: Middle item: 4

8.50. An alpha particle of mass 4 u moving with a velocity 2000 m/s collides with a carbon atom of mass 12 u at rest. The alpha particle is scattered through an angle of 30°. Considering the collision to be perfectly elastic, calculate the velocities of both particles after collision and the scattering angle of the recoiling carbon. Describe this collision in the CMCS.

Show that if A and B are matrices which don’t commute, then eA+B = eAeB, but if they do commute then the relation holds. Hint: Write out several terms of the infinite series for eA, eB, and eA+B and do the multiplications carefully assuming that A and B don’t commute. Then see what happens if they do commute.
