10 points.) a stone weighing 0.7 kilograms rolls down the inclined plane from position b to position a. position a is located at sea level. the inclined plane is 0.25 meters high. the difference in the gravitational potential energy of the ball between positions a and b is joules. (use pe = m × g × h, where g = 9.8 n/kg.)

Answer : 1.715 J

Explanation :

It is given that :

Mass of stone, m = 0.7 kg

The ball rolls down the inclined position from B to A and position A is located at sea level.

Height of inclined plane, h = 0.25 m

Gravitational potential energy at point A = 0 ( since, at point A PE = 0 )

Gravitational potential energy at point B = m g h

where,

m is the mass of ball

g is acceleration due to gravity

h is the height

So, at B potential energy will be :

So, the difference in the gravitational potential energy of the ball between positions A and B is :

Hence, this is the required solution.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
