The magnitude of the acceleration of the ball while coming to rest is 477.43 m/s²
The direction of the acceleration of the ball is downwards
The given parameters
initial velocity of the ball, u = 0
height above the ground, h = 2.2 m
time of motion of the ball, t = 96 ms = 0.096 s
The magnitude of the acceleration of the ball while coming to rest is calculated as;
let the downwards direction of the acceleration be positive
The direction of the acceleration of the ball is downwards

Answer:
C. Inhibit the flow of electrons
Explanation:
The metals that have free electrons are called conductors. The electrons are responsible for conducting currents in conductors since they are free to move around.
The motion of electrons is such that the former electron will occupy the hole produced by the latter electron where the latter moves forward in the conductor in one direction. It is similar to the snooker ball hits a ball and occupies its position where the other moves forward hitting the other and occupying its position.
The neutrons are fixed with the atom and they cannot move in the metallic conductors.
Insulators are materials that do not have free electrons. So, it does not account for such motion of electrons.
So, the insulators inhibit the flow of electrons since there are no free electrons to share the energy.
Explanation:
Following are the steps taken
1. To turn off the wave in the wave pool press the emergency turn off button (E-stop).
2. Winding of river or shutting off flow of water in the slide.
3. Dispatch of riders at speed slide is stopped.
This would be called elevation
1 is the body cell and 2 is the gamete. he reason is because the 1st one consists of more chromosomes than the second. a gamete will only consist of 23 while a body cell will consist of 46
