48 you are given two amplifiers, a and b, to connect in cascade between a 10-mv, 100-k source and a 100- load. the amplifiers have voltage gain, input resistance, and output resistance as follows: for a, 100 v/v, 100 k,10k, respectively; for b, 10 v/v, 10 k,1 k, respectively. your problem is to decide how the amplifiers should be connected. to proceed, evaluate the two possible connections between source s and load l, namely, sabl and sbal. find the voltage gain for each both as a ratio and in decibels. which amplifier arrangement is best?

Ithink it is c ,i hope i you

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
