What term best describes a major influence on image resolution for most CT scanners: - Voxel Photon Energy Formula - E=hv=hc/wl E=hf=hc/wavelength(lambda) h=Planck constant = 6.6261x10^-34 JS Speed of light = 3e8 f=photon frequency lambda = photon wavelength Which instrument would be the most appropriate choice for monitoring radiation leakage from a Cobalt- 60 source (with the source in the off position)? - radiotherapy verification film The number of atoms in one gram for any materia...

Atomic Number - correct answer number of protons found in that atom; low number; (Z) Mass Number - correct answer Protons + Neutrons; high number; (A) Atomic Mass - correct answer relative mass of that atom compared to the mass of a carbon-12 atom (which is set at 12.00); measured in amu; 1 amu = - correct answer 1.66x10^-24 Atomic Weight - correct answer weight (g) of one mole (mol) of a given element (g/mol); the weighted average of all the masses (not the weights) of an element, w...

Quantum Mechanics-Chemistry Of these electromagnetic waves, which has the longest wave length, greatest energy, greatest frequency, lowest amplitude? ️1. Wavelength is the distance between identical points on successive waves. Wave B has the longest wavelength. 2. Frequency is the number of wavelengths that pass per unit time. Since all electromagnetic waves move at the same speed (the speed of light), equal distances represent equal amounts of time. In the same distance, wave A s...

Quantum Mechanics History Planck ️Energy is discontinuous, quantum Einstein ️Light is both a wave and particle(Photoelectric effect) Bohr ️Bohr Model of Atom, electrons move in fixed orbits around nucleus, energy levels are quantized DeBroglie ️Matter is both a particle and a wave Heisenberg ️Uncertainty Principle:Can't know both location and velocity of a particle. Schrodinger ️Wave functions, orbitals, and quantum mechanical model

The majority of older adults say that they feel irritated or angry much of the time. T or F? Ans False - Older adults are no more angry or irritated than younger adults. Individuals who are angry or irritated a good portion of the time while younger will probably be individuals who are angry or irritated a good portion of the time in old age. Over 12% of the population of the US is over the age of 65. T or F? Ans True - the percent of older adults in the US has been steadily increasing. I...

AAMC FL 1 Exam Questions and Answers 2024 If Reaction 2 (Figure 4) is repeated with HCl and the compound shown below, which of the following compounds is NOT a direct product (without rearrangement)? -Answer-Compound A requires a hydride shift to form- therefore not a direct product. NOT an SN2 reaction because of tertiary alcohol- it is SN1 What is the energy of the photons emitted by the LED at a frequency of 610 THz? (Note: h = 6.6 × 10-34 J·s) -Answer-The photon energy is the energy...
