I do not know of the following in your class, but the wall is still and non-moving, while the hockey player is pushing off of it, as stated. So, this is not inertia, for a fact, because the wall is not moving towards the hockey player.
The essay will highlight the fact that for every simple machine, there is always friction involved. As per the law of conservation of energy, the energy input to a system is equivalent to the energy output. Some of this output is in the form of friction, which is not useful. As the moving parts in a machine increase, it becomes more complex and more friction is generated between its parts. Therefore, a complex machine ends up being less efficient.
Answer:
Answer is = 12.3 x 10^6 N
Explanation:
We need to calculate force on the charge which is in Newtons:
Formula is = K q1q2/r^2
k is constant depeneds on the permitivity of the medium and its value is 9x10^9 Nm^2/C^2
q1 and q2 are charges and r is the distance between these two charges so just by putting values we get F= 9x10^9 x 1.1x10^-6/(8x10^-2)^2 (we get the above answer in newton)
it occur kinetic energy

vehicle.
