(k = 8.988 x 109 N-m 2/C 2) correct answers where k is Coulomb's constant (e = 1.6 X 10~19 C) correct answers The smallest possible unit of charge is one electron unit An electric field is defined as the electrostatic force per unit charge. The symbol for any electric field is E and is vector and have units of N /C or V/m correct answers what is E E=kq/r^2 correct answers For a point charge, the electric field is found by dividing Coulomb's law by q, giving: F=qE correct answer...

What does the term force describe? correct answers an outside influence on an object. What is a frame of reference? correct answers means that if the placement of one object is known, it is easier to locate another object with respect to the position of the original object. What is speed a measurement of? correct answers an objects movement or change in position (x), over a change in time (t). What is the measurement of speed with direction called? correct answers velocity What is th...

PASSAGE: Wavelength: 266 and 325 Power (mW): 1.5 and 2.2 Pulse duration (ms): 5 and 2 Which laser is suitable for the MALDI technique after its frequency is doubled? A. Laser A: wavelength 826 nm, power 1.2 mW B. Laser B: wavelength 714 nm, power 1.2 mW C. Laser C: wavelength 650 nm, power 1.5 mW D. Laser D: wavelength 532 nm, power 1.5 mW correct answers The answer to this question is D because the wavelength must be either 266 nm or 325 nm, and by doubling the frequency of the laser...

Cytochrome c oxidase correct answers An enzyme responsible for electron transfer in the ETC, so inhibiting it would slow or stop the ETC. Dosing of Blast Phase Chronic Myeloid Leukemia (BP-CML) cells with cyanide would result in: correct answers Reduced intercellular ATP and apoptosis or necrosis. Cyanide binds to cytochrome c oxidase and prevents electron transfer. Inhibiting cytochrome C oxidase would decrease ATP production. thus, large dose would also cause cell death (apoptosis or ne...
