Ascanning tunneling microscope is used to measure small changes in height of a surface by detecting changes in the tunneling current between the tip and the surface. the current is proportional to the tunneling coefficient (ie. i = const * t) which follows the general equation for tunneling through a square well , with c dependent on the molecule and l is the distance. the transmission coefficient at one point is t = 0.01, what is the relative current if the distance is increased from l to 5l? we are interested in i(5l)/i(l). (note: there may be more information provided than you need to solve the problem.)

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way

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
