Physics 7B FNTs due DL.8 camera flash is an example of a RC circuit. When the camera is turned on, the battery charges up a capacitor. When the capacitor can then press the shutter button, quickly discharging the capacitor through the flash. By pressing the shutter button, the photographer disconnects the capacitor from the voltage source. This also connects the charged capacitor to the camera flash resistor. is fully charged, usually indicated by a light on the camera, you a) Draw a RC circuit representing how the camera flash system works. Draw two voltage versus time graphs for this system, one showing the voltage across the capacitor when the it is charging and one for when it is discharging. Describe how the two plots are related. b) Based on your knowledge of exponential growth and decay, come up with the equation for charging and discharging the capacitor in the camera, given the battery, resistors, and capacitor. c) Given that flash resistor value is R= 3Q, and the capacitor has capacitance C-150μF, find the time constant t. d) e) Given the battery is ε=5V, find the time it takes for the fully charged capacitor to discharge by 1/3.

the answer is to check all of them! they all apply well at least i think so!

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

find the sum of the two horizontal vectors and the sum of the two vertical vectors

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
