potential energy because it has the ability to do work
Explanation:
A rock resting high in a cliff is an example of potential energy because it has the ability to do work. This form of energy is called potential energy.
- Energy is defined as the ability to do work. To do work, force must applied using energy to move a body through a particular distance.
- A body at rest is not doing any work. This is the case with potential energy of the body on a high cliff.
- At the state of rest, it is not doing any work.
- The potential energy of this body expresses the ability of such body to do work.

Answer:
0.0483m or 48.3 mm
Explanation:
Let g = 10m/s2
At 8m, the pile has a potential energy of
P = mgh = 3000*10*8 = 240000 J
This energy is converted to kinetic energy once the pile drops down to the bottom:
Taking gravity into consideration, the net force acting on the pile once it hits the ground is
Therefore the net deceleration is:
We can find out how far it's driven into the ground with the following equation of motion:
where v = 0 is the final velocity, which is 0 because it stops, is the initial velocity when it hits the ground, a is the deceleration, and s is the distance it travels into the ground
or 48.3 mm
The subduction zone is the zone in the crust of the Earth where tectonic plates meet.
Magma is a hot fluid formed in the crust. This fluid is the one from which lava is formed.
Most magma that is formed in this region never reaches the surface. However, if it does, belts of volcanoes will be formed.
Answer:
Maximum magnetic field will be 0.288 T
Explanation:
We he given number of turns in solenoid N = 23800
Length of the solenoid l = 1 m
So number of turns per unit length in the solenoid
Maximum current in solenoid i = 100 A
Magnetic field due to solenoid is equal to
As the current is maximum so magnetic field will be also maximum
So maximum magnetic field will be 0.288 T
