The conducting path between the right hand and the left hand can be modeled as a 8.0-\rm cm-diameter, 180-\rm cm-long cylinder. the average resistivity of the interior of the human body is 5.1\omega\; m . dry skin has a much higher resistivity, but skin resistance can be made negligible by soaking the hands in salt water.
if skin resistance is neglected, what potential difference between the hands is needed for a lethal shock of 100 \rm ma across the chest? your result shows that even small potential differences can produce dangerous currents when the skin is wet.
express your answer to two significant figures and include the appropriate units.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
