The formula for the potential energy, EP is given by
EP = m × g × h
where:
m is the mass in kilograms
g is the gravity (9.8 m/s²)
h is the height in meters
EP = 6 × 9.8 × 2 = 117.6 kg-m²/s²
A) GPS monitoring of plate speeds and movements.
Explanation:
The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.
A GPS is a Global Positioning System made up of series of components.
- Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
- The recent advances uses a GPS system to monitor real-time movement of the plates.
- The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
- From the sensors, observatory stations can know and duly observe how plates are moving.

Answer:


Δd = 
Explanation:
As
, when the car is making full stop,
.
. Therefore,

Apply the same formula above, with
and
, and the car is starting from 0 speed, we have

As
. After
, the car would have traveled a distance of

Hence 
As
we can simplify 
After t time, the train would have traveled a distance of 
Therefore, Δd would be 
Answer:
I think it would be a chemical change.
Explanation:
Because a physical would be like crushing it or something along that line.
It is c which is four minutes per day
