An electron moves along the z-axis with vz=3.0×107m/s. As it passes the origin, what are the strength and direction of the magnetic field at the following (x, y, z) positions? a) (2, 0, 0)... Bx, By, Bz = ?
b) (0, 0, 1)... Bx, By, Bz = ?
c) (0, 2, 1)... Bx, By, Bz = ?

b.transmitters send radio waves, and receivers capture radio waves.

3.2x10^7

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
