Sphere A carries a net positive charge, and sphere B isneutral. They are placed near each other on an insulated table. Sphere B is briefly touched with a wire that is grounded. Whichstatement is correct? (Points: 1)

A. Sphere B remains neutral.
B. Sphere B is now positivelycharged.
C. Sphere B is now negativelycharged.
D. The charge on sphere Bcannot be determined

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

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
