a. Out of the sphere into the balloon
b. Into the sphere from the balloon
c. From the left side of the sphere to the right side
d. From the right side of the sphere to the left side
e. Out of the sphere into the surrounding air
f. Into the sphere from the surrounding air
g. Nonsense! There is no movement of electrons

answer; the correct answer is technician a; ///100%good luck

b.

explanation:

10.0

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
