The charge on one electron is 1.6 x 10^-19 Coulombs. The electron beam in an oscilloscope has 3.4 x 10^7 electrons flowing per second and the accelerating voltage is 15 kV. What is the effective resistance of the space the electrons flow through?

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

The  asthenosphere  is now thought to play a critical role in the movement of plates across the face of earth's surface. according to plate tectonic theory, the lithosphere consists of a relatively small number of very large slabs of rocky material.
