You betcha !
-- Work is done whenever a force acts through a distance.
-- The skydiver has weight. That's the force acting on him.
-- As time goes on, I'm assuming that he falls from one height
to a lower height. That's the distance the force acts through.
-- The work done on him is (force) times (distance)
(his weight) x (distance he falls).
So where is the machine that does all this work ?
-- It's GRAVITY that does the work on him as he falls.
So how did he get all this energy in the first place ?
Where did it come from ?
-- From the airplane that lifted him up to height from which he jumped !
It's being planned to launch in the 2020's
Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Current<span> is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. ... Physicists consider </span>current<span> to flow from relatively positive points to relatively negative points; this is called conventional </span>current<span> or Franklin </span>current. Electrons, the most common charge carriers, are negatively charged.
Voltage<span> is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from electric potential energy by noting that the "potential" is a "per-unit-charge" quantity.</span>
The electrical resistance<span> of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: If the </span>resistance<span> is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.b
