Triply charged uranium-235 and uranium-238 ions are being separated in a mass spectrometer. (the much rarer uranium-235 is used as reactor fuel) the masses of the ions are 3.90*10^-25 kg 3.95*10^-25 kg, respectively and they travel at 3.1*10^5 m/s in a 0.29 t field. what is the separation between their paths in meters when they hit a target after traversing a semicircle?

What are similarities and differences of reflection, refraction, diffraction and absorption?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
