14.1.6 Quiz: Conservation of Momentum
2 Points
Two skaters, at rest and facing each other, push off each other. Their initial
velocities and momenta are zero, but their final momenta are not. How can
the total initial momentum (which is zero) equal the total final momentum,
since both skaters are now moving? (Remember that momentum is a vector.)
A. One skater must be much larger than the other.
B. Momentum is not conserved in this case.
C. This is not an isolated system, so the conservation law does not
apply.
D. The skaters are moving in opposite directions. One momentum is
positive and the other negative, so their values add up to zero.

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?

Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?
