A large drill is used to make a hole through rocks in the earths surface to excavate for oil
what's the equation that links change in gradational potential energy store , mass , gravitational field strength ,height

Explanation:

The gravitational potential energy of an object is the energy possessed by the object due to its location in the gravitational field.

This energy is always measured as a difference with respect a "zero level" - generally taken as the ground level.

Therefore, it generally makes more sense to measure the change in gravitational potential energy of an object when its height is changed; this is given by:

where:

m is the mass of the object

is the acceleration due to gravity

is the change in height of the object

if you answer my question i will answer yours

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
