Hey everyone!
I will be passing out of high school in three months' time and I will most probably be taking up a course with honours in physics. I will be doing my undergraduate studies in my home country (India). I want to know whether its worth going to the U.S./U.K. for a master's degree or...
haruspex has put it in a good way...just have a closer look at the quote
Strictly speaking from the questions perspective perhaps the force acting to accelerate the printer could be increased, the actual head could be made lighter so it accelerates faster...etc (gosh am I breaking any guidelines!?)
I don't think there are any calculations involved...the numerical answer you computed only works in ideal situations (like zero friction, drag, etc). The answer to the last part must be qualitative not quantitative because they haven't given you any data to compute losses in speed due to the so...
Well, they've given you the mass, the forces and the distance the head needs to cover. You've got to know that everytime the printer gets ready to print a character, it's velocity is zero. But, force acts on it AFTER printing the character, so then you've got to calculate the velocity it attains...
I don't understand the condition of saturation in an npn transistor (common emitter config). My textbook says that the collector-emitter voltage reduces to near zero upon increasing input voltage. Also, Wikipedia says that both BE and CE junctions 'become' forward biased. Can anyone please...
