Answer:
If a body is electrically neutral it means it has no net charge.
Explanation:
Because it has the same number if protons as it does electron , which are opposite charges that offset eachother.

Answer:
0.026 meter
Explanation:
using distance time equation to determine the time for the puck to move 16.5 meters.
distance 'd' = velocity'v' x time't'
16.5 = 44 x t
t =0.375 second
Here momentum is conserved. Since both objects are initially at rest, the initial momentum is 0.
Next is to determine the puck’s momentum.
Momemtum 'p' = m x v => 0.15 x 44 = 6.6kg⋅m/s
The player momentum is -6.6kg⋅m/s .
In order to determine the player’s velocity, we'll use p=mv
-6.6 = 94v
v= -0.0702 m/s
The above negative sign represents that the player is moving in the opposite direction of the puck.
Lastly, how far does the player recoil in the time it takes the puck to reach the goal 16.5 m away?
d = v x t = 0.0702 x 0.375= 0.026 meter
