The table lists information about four devices. A 4 column table with 4 rows. The first column is labeled device with entries W, X, Y, Z. The second column is labeled wire loops with entries 60, 40, 30, 20. The third column is labeled current in milliamps with entries 0. 0, 0. 2, 0. 1, 0. 1. The last column is labeled metal core with entries yes, yes, no, no. Which lists the devices in order from greatest magnetic field strength to weakest? W, X, Y, Z W, Z, Y, X X, Z, Y, W X, Y, Z, W.

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

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
