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.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
