Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Chapter 29 – Electromagnetic Induction

Faraday’s Law of Induction: - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop. dt ε= − dΦB - Increasing flux ε< 0 ; Decreasing flux ε> 0 - Direction: curl fingers of right hand around A, if ε> 0 is in same direction of fingers (counter-clockwise), if ε< 0

Chapter 6 – Force and Motion II

A centripetal force accelerates a body by changing the direction of the body’s velocity without changing its speed. v, a = ctes, but direction changes during motion.-Centripetal force: a, F are directed toward the center of curvature of the particle’s path. 3 III. Non-Uniform circular motion

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

Most abundant isotope of Ar is at mass 40 which dramatically interferes with the most abundant isotope Of Ca at mass 40. Combination of argon and oxygen in an aqueous sample generates the 40Ar16O+ interference, which has a significant impact on the major isotope of Fe at mass 56.

Gas Chromatography-Mass Spectroscopy

The fragments are charged ions with a certain mass. The mass of the fragment divided by the charge is called the mass to charge ratio (m/z). Since fragments produced by EI have a charge of +1, the m/z represents the molecular weight of the fragment. Ions created in the EI source are focused into the ion trap. The trap consists of two hyperbolic ...

Moles Lab Activities

The answer to question #19 is C-12, the reference isotope for atomic masses. Moles Lab Activity 2: Elements Time: Students will need about 5–10 minutes at each lab station to do initial calculations and measurements. They will need a total of 15–20 minutes to complete all questions, some of which could be completed at home.
