Homework Statement Design a “smart” branch with resistors and a diode pair such that the branch resistance drops if the voltage applied on the two ends of the branch is too high, and vice versa, (i.e., the branch resistance increases if the voltage applied on the two ends of the branch is...

ok i get it now thanks.

ummm i still don't get it ... i just don't think c was possible, alkyl hailde to alkyne? how ? the only one that's possible of doing this was condensation reaction, i think.

umm well i got two equations, the first one would be D=1/2at^2, (downward ball after it has reached the highest point then free fall.), the second would be D=v/mst-1/2at^2, upward motion slows down by gravity. then?

hello, ok i will get straight to the point i don't get the following questions: Indicate the following type of reation that is taking place, and also give an example. a) Alkyl halide to alcohol b) Alkyl halide to alkene c) alkyl halide to alkyne d) alkene to an alcohol i tried a), i got...

Question 1: A ball is dropped from the top of a building and it strikes the ground with a speed of v m/s. From ground level, a second ball is thrown straight upward with the same initial speed of v m/s at the same instant that the first ball is dropped. Ignoring air resistance, determine at what...

Hello, the question i have here is: Fifty millilitres of a 0.05M solution of Sodium Carbonate is added to 80mL of a 5% by mass solution containing Siliver Nitrate. The product of the reaction are solid Siliver Carbonate and a solution is evapourated to dryness, leaving a mixture of salts. How...

wait, we just factor them out? wow, that's cool thanks. But why did you mutiply the two vectors? Because they are perpendicular? For the last question i know that their sum has to be zero, but where would you place them? why are the angles fixed? it doesn't have to fixed, it could have a degree...

ah i see, sorry, we were suppose to give out hints.

umm i solved it: Convention is that up the slope is positive, down the slope is negative. Force parallel to the slope: Fx = mg sin @ = (40)(9.8)(sin18.5) = 124.38N since this force is down the slope it's considered negative. (You are pulling it up the slope, that force can be considered...

hello, i have a few theories questions to ask. (i don't know where to start for question such as these...) Question: By considering the angles between the vectors, show that vector A + vector B and vector A - vector B are perpendicular when |A| = |B|. Question: Prove for any vectors A and B...

Hello, please help me out on this: Two equall masses lie on each side of a rough wedge, connected by a string, the wedge makes anlges 53, and 47, to the horizontal, find the coefficient of friction for the masses to move at a constant speed. MY THINKING: since masses are equal: mgsin(53) =...

yea i tried that, but a strange number came out... i will try again, maybe it's a algebra error.

i see i see, thank you, the way you did that seems simple. Yet complicated, with all the variables, but i did understood that,thanks.

i drew a digram for the forces and i found out the equations for accerleration... then I'm stuck... Question: Determine the tension in the strings, the acceleration, and how far the masses will go in 2.0s. (See attachement) Well i drew a FBD, ,and i got three eqations for accerleration...
