Which of the following materials is ferromagnetic? Iron Cobalt Nickel Aluminum

A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two isotopes is 16 to 18, the mass of oxygen-16 is 2.66-10-26 m S they are singly charged and travel at 5.106 in a 1.25 T magnetic field. What is the separation Ad=2r₂-2r₁ between their paths when they hit a target after traversing a semicircle? Ion source F=qE FE Ad= F = qvB FB Things to Prepare: 1. Make a list of information given to you. + m Bout V 12r₁ 212 m₂ 2. Identify the formula for the radius of the trajectory for particles in the magnetic field. 3. Set - up the formulae in step 2 for the two for the particles. 4. How can you manipulate the formulae in step 3 to solve for the answer? Bout kg, and

An accelerating voltage of 2.36 x 10³ V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 37.9 cm away. (a) What is the magnitude of the deflection on the screen caused by the Earth's gravitational field? (b) What is the direction of the deflection on the screen caused by the Earth's gravitational field? up down east west (c) What is the magnitude of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 μT down? east m (d) What is the direction of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down? north south west mm (e) Does an electron in this vertical magnetic field move as a projectile, with constant vector acceleration perpendicular to a constant northward component of velocity? Yes No O No (f) Is it a good approximation to assume it has this projectile motion? Yes…
