How much work must be done to increase the speed of an electron (a) from 0.18c to 0.19c and (b) from 0.98c to 0.99c? Note that the speed increase is 0.01c in both cases.
write the slope-intercept form of the line that passes through (-4-3) and in parrallel to the line t=-1/3x +3
Isn't the molar mass 92.09 g/mol? This is what i got with /\T=Kf*m formula. If that's the case then C3H8O3 is the empirical formula and the molecular formula. Correct?
A plant hangs from a 1.9 cm diameter suction cup affixed to a smooth horizontal surface (there's a figure but it's pretty simple, a plant in a plant pot hanging from a couple wires, but what seems to matter is the suction cup part). (a) What is the maximum weight that ...
A spy satellite orbiting at 160 km above Earth's surface has a lens with a focal length of 3.6 m and can resolve objects on the ground as small as 30 cm. For example, it can easily measure the size of an aircraft's air intake port. What is the effective diameter of the...
5. A bomber is flying at a height of 9 km at 800 km/h. How far in front of the target should he drop his bombs? show formulas*
Visible light is incident perpendicularly on a diffraction grating of 200 rulings/mm. What are the (a) longest, (b) second longest, and (c) third longest wavelengths that can be associated with an intensity maximum at theta=30 degrees?
D. The 3+ on Fe3+ tells you how the charge differs from its natural state. Because an electron is a negatively charged particle when one electron leaves, the charge is +1 because the ion still has the same amount of protons with one less electron.
True. The flouride anion is an ion of fluorine. Fluorine has only one oxidation state, of -1. WHY: Fluorine is the most electronegative element on the periodic table meaning that having an extra electron is very energetically favorable. (It "wants" one electron) In t...
