Answer: Capacitor
Explanation: A capacitor stores energy as charge in an electrical field between two conducting plates called electrodes which allows the flow of electrons between them.
The initial speed of the object was 6.26 m/s.
Acceleration of the sled, a = -g*μk
= -9.8*0.2
= -1.96 m/s^2
Let u is the initial speed and v is the final speed.
Applying, v^2 - u^2 = 2*a*d
0^2 - u^2 = 2*(-1.96)*10
u = sqrt(2*1.96*10)
= 6.26 m/s
The kinetic friction coefficient μok is the ratio of the friction force to the normal pressure experienced by a body moving on a dry, non-easy floor. The determination of μok may be achieved quite appropriately through an alternative creative mechanism described with the aid of Timoshenko
The coefficient of friction (fr) is quite a number that is the ratio of the resistive force of friction (Fr) divided with the aid of the everyday or perpendicular force (N) pushing the items collectively. it is represented by the equation: fr = Fr/N.

Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. Hope this helps!!!
Explanation:
according to my understanding, the value of gravitational acceleration changes because;different planets have different gravitational pull.
for example you may ask yourself why is it that the gravitational acceleration is not the same on earth and the moon.
this is because the gravitational force acting on an object on earth is greater than the gravitational force acting on an object and the Moon .
You know the moon is located in the space and one can fly, stand,dance etc.
all because the gravitational acceleration is low.
as for me when the distance from the centre of the Earth increases,
the gravitational acceleration decreases.
A good example is given by the moon.
The moon is miles away from the Earth and its gravitational acceleration is quite low .hope you got me.
